PiFire v1.10.1 (Halloween 2025)

Fixed an issue where the SPI device number was not being properly configured for SPI displays. This caused issues when using SPI device 1 instead of the default SPI device 0. SPI Device needs to be selected in the display configuration during the configuration wizard process.

Full Changelog: v1.10.0...v1.10.1

PiFire v1.10.0 (2025-10)

Upgrade Note: If you are upgrading from a very old version or have been upgrading from versions older than v1.7.x, you may want to consider doing a full re-installation. While the upgrade may work, there may be some unexpected version differences in components that may cause issues. The upgrade script will do its best to get everything setup correctly, but in some instances, this may fail and you may need to recover or re-flash the system.

This release contains bug fixes and feature updates since the previous version.

Here are just some of the NEW features that were added in this update:

• Quality of Life: Added Python Module List to the admin page (Admin > Module List). This will show you the modules that are installed and their version numbers. This is useful to debug common package version issues.
• Installer Improvements: For fresh installations, Raspberry Pi OS 12 (Bookworm) (32/64-Bit) is recommended. This is the last stable release of Raspberry Pi OS and is highly recommended for new installations. If you are running an older version of Raspberry Pi OS, you can still upgrade. For Bookworm 64-Bit, this new installer will install UV and will log the installation process to a file in your home directory. Note: If you are using the DSI connected display, you will need to use only 32-Bit Raspberry Pi OS (Bullseye or Bookworm) due to the changes in display drivers in the 64-Bit version.
• Logging: Added rotating log files to the PiFire logging system. This will help keep the log files from growing too large and will allow you to easily view the logs in the log viewer page (Events > Logs). The log files will be rotated every 1 MB and will keep the last 3 log files.
• Safety: Added notification capability to the process monitor, so that it can notify the user if the control script crashes. Updated the default and basic dashboards to display an error message when a critical error is detected, such as the control process crashing.
• Settings Dashboard Select: Added a screenshot when selecting dashboard.
• System Information: Added system information functions to the Grill Platform modules. Overhauled the system information card in the Admin page to display relevant information.
• Hold After Start: Added a toggle option (Settings > Startup & Shutdown) to always ask what hold temperature to use after startup. This will only work in the web interface currently.
• iBBQ/xBBQ Support: Added support for the iBBQ and xBBQ Bluetooth thermometers. Changes submitted by Discord user @faz (many thanks!) when they found that the newer firmware for this device (xBBQ) wasn't working properly. With these changes, both the older version and the newer versions should be supported.
• PWM/DC-Fan: Added setting to select a custom duty cycle for the PWM/DC Fan during startup.
• Notifications: Support for WLED notifications via presets. Use a WLED device to show the current mode or certain notification events.
• Probes: Added support for the 6-probe Inkbird IBT-6XS Bluetooth thermometer. This is a popular Bluetooth thermometer that is widely available. Many thanks to Discord user @don Gray for contributing and testing this device.

Behind the scenes improvements including:

• Changed install script to utilize UV for creating a VENV and installing dependencies. This results in a much faster installation process, quicker upgrades and street cred. Only applicable to Raspberry Pi OS 12 (Bookworm) 64-Bit and later.
• Changed the behavior of the control script so that controller configuration can be modified while in Hold mode. This allows you to you to manually tune your PID, potentially, while running a test burn. In the future, this may be extended to allow auto-tuning capabilities.
• Moved to Flask 3.1.0 which will allow PiFire to take advantage of the new security and performance updates.
• Fresh installations will now pin all versions of the python package dependencies to improve reliability and stability.
• Updated the board-config utility to gather os information in os_info.json.
• Moved all Flask Web UI Routes to the Flask Blueprint system. This will allow for easier management of the web UI in the future and it considerably cleans up the app.py file.
• @weberbox updated the SocketIO code to support the latest version of the Android app. Moved SocketIO to use Flask-SocketIO Blueprints for better organization.
• Moved the events.log file back to the /logs folder instead of the /tmp folder. This is to ensure that the log file is not lost on reboot and can be easily accessed by the user.
• Added self-signed certificate generation to the installer script. This will allow for HTTPS support out of the box. Note that this is a self-signed certificate and will not be trusted by your browser. You can replace it with a trusted certificate if you wish.
• Updated the installation script and board-config utility for Raspberry Pi Trixie installation. Specifically check for OS Version ID and install appropriate packages.

Here are some bug fixes in this update:

• Fixed bug with fresh installations where Redis python 6.0.0 deprecated charset encoding parameter. Pinned to Redis Python 5.3.0 for now.
• Development Environment: Unable to complete wizard setup because it falsely detects real hardware. Root Caused to Python Exec when launching wizard.py
• With Socket IO changes from weberbox, unpack_thumb is broken in cookfile route. Root caused to added ID parameter in the cookfile module.
• Global control panel fix in base.html where control was being over written to a boolean.
• Cookfile: Uploading a new image/thumb after previously uploading an image or thumb would cause the page to crash.
• Celsius mode shows negative temperatures when no probe is connected with ADC devices. Changed to show 0C when no probe is connected or temperature is less than 0C.
• Fixed a bug where probe configuration was not being loaded by the Jinja template because it was not looking in the right blueprint path.
• Added rotation to the Raspberry Pi DSI Display, which was previously missing. This includes translation for the touch interface.
• Fixed a bug where the control script would crash when predicting the ETA for a probe set temperature. This was due to the Linear Regression model returning an infinite or NaN value.
• Fixed a bug introduced into the Configuration Wizard with PCB / Board selection. When moving to Flask Blueprints, missed the wizard configuration card location changes.
• Updated board-config utility to use pwm-2chan instead of pwm for dtoverlay settings on the Raspberry Pi. This is to ensure compatibility with the latest Raspberry Pi OS releases.
• Wizard would display probe profiles for devices that don't use a probe profile. Now it should simply say NA (Not Applicable) for devices that do not use profiles (i.e. non-ADC devices).
• Fixed various bugs/issues when installing on a Raspberry Pi 5. Note that for DSI display to function correctly, you must use the 32-Bit Lite version of Raspberry Pi OS (Bookworm) due to changes in the 64-Bit display drivers. Since the 32-Bit version of Raspberry Pi OS has a 64-Bit kernel, you must use the '-venv' option for the installer script.

Full Changelog: v1.9.0...v1.10.0

PiFire v1.9.0 (2025-04)

Upgrade Note: If you are upgrading from a very old version or have been upgrading from versions older than v1.7.x, you may want to consider doing a full re-installation. While the upgrade may work, there may be some unexpected version differences in components that may cause issues.

Here are just some of the NEW features that were added in this update:

• Minor overhaul of manual mode, moving the controls to the control panel so that you can control the grill outputs directly from the dashboard if you desire. Buttons and PWM slider is responsive without reloading the page. Improved manual mode instructions.
• Added the ability to manually override outputs (igniter, auger, fan) on the default dashboard and on the flex touch display. The user can enable this in the safety settings, and select the amount of seconds to override the controller during operation. Use with caution as this can potentially leave the igniter on for extended periods of time.
• Added high and low limit temperature notifications for each probe. This allows you to to set limits for the high and low temperatures and be notified when they exceed those limits during operation. These limits do not expire, but will only trigger once they are exceeded. They will reset when the temperature falls below/above the high/low limit. This feature also allows you to take some actions such as to reignite the grill if the temperature goes too low or to shutdown if it goes too high.
• Added iBBQ Bluetooth probe support. Tested with Inkbird BT-4XS. The device may take some time to be detected and setup before data is is streamed out to the dashboard.
• User @dogtreatfairy contributed two new controllers including an auto-center PID controller and a PID controller with Smith Predictor. Github user @markalston contributed a new clamping PID controller. Select these controllers in the settings page.
• Added ST7789V with Encoder support. This should still be considered experimental, as it uses an unsupported forked ST7789 library for display support. Note that if you select this display version, it will install this forked library and will cause the original ST7789 library not to function anymore.
• Added option to delete all debug log files. This can help with debugging issues, so that we have a clean log file to work with.
• Added support for Meater Bluetooth probes (Meater Pro is still under development). This is a work in progress and may not be fully functional. The probe must be configured in the Wizard before it can be used. The probe will automatically connect to the PiFire device when the device is powered on. The probe will also automatically disconnect when the PiFire device is powered off. The probe will also automatically reconnect if the PiFire device is rebooted.
• Added device status structure that can be retrieved from the /api/current route. This includes the current state of the device, the current configuration, and the current status of the probes. This allows the dashboard to display connection status and/or battery status for bluetooth probes.
• Added support for the ILI3941 display with the flex framework. This utilizes the same framework as is being used for the DSI Touch display, and will allow for the ILI9341 display to be customized, as well as allow for the use of different resolutions. (note 480x320 is not currently implemented)
• Added bluetooth scanning in the configuration wizard so that you can select the hardware ID of a bluetooth device that you want to use. It will flag hardware ids that are already in use, but it won't prevent you from setting them.
• Update the probe configuration wizard to hide/show profile selection based on the probe device. Only ADC devices should show profile selections. Also hides/shows the probe enabled selection based on the probe type (AUX is by default hidden).
• Updated the probe configuration in the settings page. The default dashboard also has probe configuration built in, using the cog in each of the probe cards.
• Removed hopper level from the different display types when no hopper level / distance sensor is enabled.
• Added a button & menu option to the flex supported displays (DSI Touch / ILI9341f / Prototype Flex). Added a button/status icon in the status card for the default dashboard. You can click on this icon during hold mode to toggle lid/door open.
• Added touch screen mode to the default dashboard configuration, which provides some visual and UI changes that will make using a touch screen device easier.
• Github user @markalston contributed the ST7789 240x240 display layout and support in a new module.
• Github user @wightmanjr contributed the ILI9488 320x480 display modules including encoder and button support.

Behind the scenes improvements including:

• Changed order of component installations when installing modules from the wizard. The wizard will now install apt packages before installing python modules to match dependencies for items like bluepy.
• Added Lid/Door toggle API call which allows you to manually toggle on/off the lid/door open pause for the controller in Hold mode.
• Added a nicer Nginx server error landing page that will attempt to load the root ('/') every 10 seconds, provides a link to the Supervisor, and other helpful links. This currently will only be available on new installations.

Here are some bug fixes in this update:

• Removed certain unsupported rotations from the ST7789 320x240 display configurations. (90/270 degrees are not supported by the ST7789 driver module)
• Fixed a missing voltage bounds check for ADC probes using Celsius units. This should prevent the probes from reporting invalid temperatures when probes are not connected.
• Github user @markalston contributed a fix for the PID controllers to prevent divide by zero errors from crashing the control process.

New Contributors

• @wightmanjr made their first contribution in #218

Full Changelog: v1.8.4...v1.9.0

PiFire v1.8.0 (2024-09)

Here are just some of the NEW features that were added in this update:

• Changed the Configuration Wizard to improve platform selection. Now you can select your PCB Board type (or Custom) and configure the available settings. The wizard will automatically assign the right GPIO pins as configured for that particular version of the board. This also removes any extraneous configuration options.
• Added transient probe configuration types so that probes can be marked as transient(not always available). This means that if probes/probe ports are not fixed (like in the case of the DS18B20 device), then the control script can return None type for the temperature. This allows the dashboard to do things like hide the card in the case where this probe isn't present.
• Default Dashboard gets the ability to set maximum temperature to display for the primary probe and food probes. This can be configured via the gear icon settings.
• Default and Basic dashboards will notify the user if connection to the server is lost (i.e. when the server is not responding to requests).
• Added ST7789V (Newer V-variant of the display) display which is currently experimental because of the use of an experimental library. This will likely change in a future release if the V variant gets added to the original library.

Behind the scenes improvements including:

• Moved all platform/board/system settings into 'platform' in the settings.json. This neatly group all of these settings in a single place so that they are not spread out across the settings configuration.
• Combined the pifire.py and pifire_pwm.py modules into a raspberry_pi_all.py module, which supports both AC and DC Fan configurations with most flavors of the Raspberry Pi single board computer.
• Created a board configuration utility that will make specific system configurations easier to perform on different single board computers. The installation, wizard and update utilities can use this tool to do board configuration as needed for enabling different features of the platform.
• Refined the auto-tuning tool to use the last sampled resistance at a given reference temperature to use for calculations. This should help to improve the accuracy of the tuning data, especially with slower probes.
• Changed the ETA function to use Linear Regression (SciKit) instead of the Interpolate module (SciPy). This will hopefully improve the reliability of the ETA function.
• Added ProtoFlex module for testing new display output system. This will be used to test the new display system and allow for additional screen sizes to be added for existing displays like ILI9341, etc. Also refactored the FlexObject and BaseFlex system to be more modular and hopefully more performant. Updated the configuration wizard so that configuration of displays is easier. Other minor bug fixes.
• Improved resilience of the control script, especially when loading probe devices. If a probe device fails to load, the probes that are associated with that device will be disabled.
• Added a critical error flag to the control script. This will be used to detect when a critical error is encountered, which may prevent further control of the system (i.e. changing modes, etc.)

Here are some bug fixes in this update:

• Fixed a bug where changing units from F to C would (during upgrade) would cause the control script to crash.
• Fixed a bug where the hopper level was not correctly displayed on startup for the flex displays. Reduced the hopper level check to once every 60 seconds during a work cycle.
• Fixed a bug on 240x320 and 64x128 displays where if pifire is not connected to the network, an IP QR Code will hang the display.

Full Changelog: v1.7.3...v1.8.0

PiFire v1.7.2 (2024-06)

Here are just some of the NEW features that were added in this update:

• Default Dashboard gets the ability to set maximum temperature to display for the primary probe and food probes. This can be configured via the gear icon settings. This is kind of a bug where the temperature stalling on the dashboard has tripped a lot of people up. This allows you to increase the maximum temperature that the gauges can display in case you want to higher temperatures.

Behind the scenes improvements including:

• Added general dashboard configuration capabilities based on metadata json files in the ./dashboard folder

Here are some bug fixes in this update:

• Fixed a bug where control.py would crash when changing units.
• Fixed bug with manual tuning where floats were entered for temperatures

User submitted changes in this update:

• Update notifications.py by @EricPalmquist in #194

Full Changelog: v1.7.1...v1.7.2

PiFire v1.7.1 (2024-05)

Yet another massive release with lots of bug fixes and feature updates since the previous version 6 months ago. I hope to make more frequent updates in the future so that we aren't seeing too many months go by without any juicy new features. So look out for v1.8.0 coming in the next couple of months (hopefully I can hold myself accountable for this).

Here are just some of the NEW features that were added in this update:

• Added experimental DSI based touch display, allowing for touch input from a DSI based display on the Raspberry Pi. As of now, this is an experimental addition and should be expected to have bugs. Performance is also a concern, as this module utilizes PyGame for displaying graphics and getting input from the touch display. This will be fairly laggy on a Pi Zero 2W (or Pi 3 A+).
• Exit Startup temperature (suggested by @EPGrillz), allows you to set a temperature/threshold where the grill will exit startup and go into the next mode. This can be configured in settings. If the grill starts hot and has already exceeded this temperature, then the grill will continue with startup for the normal amount of time.
• ILI9341 display menu and encoder improvements (submitted by @dogtreatfairy). Improves the display menu readability, adds back button and improves the encoder responsiveness.
• Added ETA feature for any probe with notification set. This ETA is calculated using an interpolation function (currently linear) which is still very much experimental. This feature will continue to be worked on and enhanced.
• Default and Basic dashboards now have the ability to show/hide cards including the hopper and status cards. Look for the gear icon in the corner of the window.
• Default, Basic dashboards and Control Panel now have the ability to take keyboard input for hold and notification values. Just click value and change it using the keyboard. The sliders will still work as normal if you prefer this.
• Added a warning to the Configuration Wizard, when the system is running/active so that you don't have to wait until the very end of the configuration to realize that you cannot submit changes. (feature suggested by Discord user @richie)
• Added support for v2.1.0 Android Application. Thank you to @weberbox for updating the app to work with the latest PiFire changes!
• Improved visibility of save buttons on the settings page. (Suggested by @chrisusernamechanged)
• Added support for DS18B20 1-Wire Thermometer, mainly to be used for calibration of other probes as it does not have adequate temperature ranges for actual grill usages. This probe is currently experimental.
• Complete overhaul of the tuning tools, including adding an auto-tuner. The tools are now more mobile friendly, meaning you can use your phone to go through the process of tuning your probes. In addition, the auto-tuner allows you to tune any of your resistance based probes against any other probe in the system (for example utilizing the new DS18B20 probe).
• New Elapsed Time card on the default dashboard which shows you the total elapsed time since startup. (suggested by Discord user @bassmanadam)
• Added safety feature to require a confirmation when pressing the startup button on the WebUI control panel. This will help to prevent false/accidental startup button presses. This can be disabled in settings if desired.
• New API capabilities including a much simplified API interface for setting and getting data. Details in the updated documentation.
• Added 'Always Prime on Startup' feature which allows the user to have a default prime amount on startup. Note that if the user selects startup again during priming that was initiated with this feature then priming will be cancelled and the grill will enter startup mode. (feature initially suggested by Discord user @tsj) This can be enabled in settings.
• Overhauled timer UI on the web interface to utilize the newly created API calls (Eventually may deprecate the /timer function) and improve the UX. Timers also will automatically detect if they have started from another source and display in the web interface.
• Attempted to address the issue on the mobile Web UI where a long Grill Name (on the NAV Bar) would push the navbar menu to the next line.
• Added wifi link quality to the admin page system information.
• Added throttling and undervoltage detection which is currently reported via the admin page system information.
• Added 'Send Test Notification' to the Notifications section of settings. Note that this will send notification to the services that have already been enabled and saved.
• New debug items added in the admin page. You can now download the 'settings.json' and 'control:general' database files directly from the debug card.
• When the dashboard is loaded it will check if the control process is alive and flag an error if the control process does not respond. This may be helpful in debugging issues as they arise.
• Behind the scenes improvements including:
• Replace 'is_raspberry_pi' with 'is_real_hardware' functions planning for future platform support.
• Add require_reboot flag to Wizard items (Added to PWM / DSI Touch Display devices) if a reboot is required when changing this configuration.
• Add general commands list to Wizard items (Added to PWM board so no manual edits are required).
• Added configuration for dashboards that allow extending/saving features for different dashboards.
• Updated the ChartJS version to v3.9.1.
• Added common deep dictionary update function that allows dictionaries to be updated in a recursive way simplifying the logic of updating dictionaries.
• Adding system level capabilities so that future functionality can be added (i.e. wifi signal strength, undervolt detection).
• Moved Push Bullet and Pushover notifications to utilize the Apprise module (no changes in how they are configured from the webUI).
• Moved most startup and shutdown settings to 'startup' and 'shutdown' respectively in the settings.json file for housekeeping purposes. Heads up to anyone working on any forks or applications that might rely on these settings.
• Added system functions/commands so that specific system commands can be customized per platform (i.e. in the future allow for other SBCs)

Here are some bug fixes in this update:

• Fixed bug with/getsize function deprecation in SSD1306 displays causing the display to crash.
• Fixed install issue with Eventlet (pinned to earlier version for Python 3.9) causing the web front end to fail with Python version 3.9 on Raspberry Pi Bullseye.
• Fixed settings upgrade logic issue.
• Fixed bug(s) with history charts streaming including a long standing bug where hidden datasets would go back to being shown when zooming/panning.
• Fixed bug (submitted by @EricPalmquist) where starting and stopping multiple times within a minute may cause a crash due to writing the same cookfile.
• Fixed a bug where probe mapping in History Page may carry extra probe information from the defaults.
• MQTT Bug Fixes contributed by @EricPalmquist
• List minute hotfix for fresh install on Raspberry Pi Bookworm

Full Changelog: v1.6.0...v1.7.0

PiFire v1.6.0 (2023-11)

In this month comes another huge update with lots of new features and bug fixes. Many thanks to the users from discord that have been testing along the way (as well as submitting some bugs), what a great community we have! Many of these features have been deployed on our development branch for some time, so they should be relatively stable. Please do file issues on GitHub if you find any new bugs with the formal release. With that, enjoy and happy grilling/smoking!

NOTE: Due to the addition of Vs (Voltage Source) and Rd (Resistor Divider) settings into the device settings of a specific device, it is important that users run the Configuration Wizard and setup these values in the ADS1115 device. The values stored in the probe profiles will not longer be used, such that the probe profiles can be used with any of the devices regardless of the Vs and Rd values. For example, in the probes device section of the configuration wizard, click on the edit icon for the ADS1115 device, edit the Vs and individual Rd settings. Once you are finished, continue with the configuration wizard and install the changes.

Here are just some of the NEW features that were added in this update:

• Added Pan/Zoom capabilities to the chart in the History/Status page
• Moved Vs and Rd settings (per-probe) to the Device settings in the Configuration Wizard so that these do not need to be configured via the profiles. WARNING: For this reason, it is required to go through the Configuration Wizard for this version to ensure that your Vs and Rd settings are correct in the device settings. So if you have an ADS1115 installed, please ensure that you are configuring it before you run the system.
• Added Auger Off Time control so that you can modify your P-Mode settings more precisely (Settings > Work Cycle)
• Added a boot-to-monitor mode (enabled in Admin > Boot Settings) so that you can go straight into monitor mode after boot. This can be helpful to debug your displays and ensure that PiFire is coming up properly.
• Added a status card to the default and classic dashboards. Shows the status of the fan, auger, igniter and P-mode (when in Smoke or Startup) with animated icons. Also displays a countdown for Prime, Startup, Re-Ignite and Shutdown modes.
• Added P-Mode selection to the default and classic dashboards. Allows you to select a new P-Mode directly from the dashboard when in Startup/Reignite/Smoke modes.
• Start Igniter in Prime Mode (Thanks to @calonmerc for the suggestion) (Settings > Pellets)
• Enhancements to PWM Fan to utilize the Hardware PWM on the Raspberry Pi. Many thanks to GitHub user @ghandye for submitting the code change.

NOTE: The user may need to make the following manual changes to enable hardware PWM support, adding this line to the end of /boot/config.txt, and rebooting:
dtoverlay=pwm,pin=13,func=4

• Add MCP9600 device support (note, this device requires a much slower I2C bus clock and may the user to manually change the bus clock frequency in /boot, however it should be noticed that it is still not stable) (Configuration Wizard)
• Add 'Logs' page to display all of the various logs that are generated for debug (can be found via Admin > Debug or on the Events page)
• Improved update feature to exclude previously installed packages, which will hopefully speed-up updates
• Added a pop-up dialog after update to show this message which is also available on the update page

Here are some bug fixes in this update:

• Add more of a description on how to use keep warm in Settings > Work Cycle
• Rate limit some error messages in the log to prevent the logs from being swamped
• Change the color of PMode on Default/Classic Dashboard for dark mode (Dashboard)
• Fix bug where the 240x320 display expects 2 food probes and crashes if there are less than two. (Thanks @ChrisUsernameChanged)
• Settings Restore Bug (apply settings and restart server) (Admin > Data Management)
• Default disable Smart Start feature. This was causing some confusion with those who are using P-Mode to control their cooks, where Smart Start was automatically adjusting P-Mode for the initial startup, based on ambient temperature instead of using the manually set P-Mode. (Settings > Startup & Shutdown)
• Fixed default cycle settings for what is recommended in the PID settings (Settings > Work Cycle)
• Fixed divide by zero error in probes/base.py
• Fixed an issue where log-levels were being overridden.
• Improved VL530L0X resilience, where sometimes long distance reads can cause the control script heartbeat to fail and crash/restart. Added this distance module to a separate thread so if there are delays in measurements, they do not cause the control script to crash.

Full Changelog: v1.5.0...v1.5.1

PiFire v1.5.0 (2023-06)

Arguably one of the biggest overhauls to PiFire since it's inception. The Probe system has been completely refactored to allow for multiple probe sensing devices (i.e. ADS1115, MAX31865, or even Virtual Probes to augment your inputs). This extension of the probe system, allows for any number of probe inputs to be tracked in PiFire, allowing from notifications and tracking of history for each probe. The sky is the limit! With this change the the probe architecture, a number of other things needed to be modified/updated, including the notification system, the history/charting, the dashboards, cookfiles and recipe modes. Note that if you are updating to this version, your settings will be upgraded in the process and you will not be able to roll back to a previous version (unless you restore from a backup of your settings).

Other Notable Updates and Features:

• One (1) Grill Probe and Many Food Probes
  • Tunable probe inputs to allow for many different probe manufacturers
  • Supports the ADS1115 ADC, ADS1015 ADC, and MAX31865 RTD devices for measuring probes
  • Probe tuning tool to help develop probe profiles
  • NEW! - Any number of probe inputs, limited only by the number of devices that the Raspberry Pi can support
    • NEW! - Virtual Probes to allow you to do things like averaging probes, finding highest and lowest values of certain probes, etc.
• Socket IO for Android Application Support (GitHub User @weberbox has made a Android client app under development here: https://github.com/weberbox/PiFire-Android) (NOTE: Due to the large amount of architectural changes in v1.5.0, the Android App update is still in development. The current version of PiFire has implemented a compatibility layer so that it doesn't break compatibility with the current Android App. If you have a non-standard probe setup or more than two food probes, you may see issues. There may still be bugs, so please do submit issues on GitHub if you experience any.)
• NEW! Recipes / Recipe Mode - Integrated recipe creation and a new mode for developing a recipe 'program' that will control the grill for you and follow the recipe that was programmed.
• NEW! Updated and re-written dashboards. The dashboard has been refreshed with a new look. New 'basic' and 'default' dashboards. If you are technically inclined, you can even develop your own dashboard.
• NEW! Control panel everywhere! Allow your control panel to be displayed on almost all pages in PiFire.
• NEW! Lid open detection during hold mode to pause the controller and prevent overshoots.
• ...And much more!
