Adding support for A/C Trotec PAC 3550 Pro

[cool-lox]

Comming from discussion board, here is my new request for adding support A/C Trotec PAC 3550 Pro.

For analyses I used : https://github.com/ToniA/Raw-IR-decoder-for-Arduino with Nano3. This was for me very helpful as it gave header info and a nice 0/1 bit structure makes it easier for me to analyse single bits. See in this sheet, may it is helpful for others too.

https://docs.google.com/spreadsheets/d/1j4H1TDJ2QRFLPnls_sxkTZ3c9922TWxqIxwyGWwBIn0/edit?usp=sharing

I can help further if other code records are needed. I think last 5% of analytics are necessary.

My workaround in absense of impleted protocol is working with Tasmota IR raw send command like :
Irsend raw,0,12024,5096,550,484,1910,010101010010001100000000000001010000000000000000001100011000100000110110

Thanks

Please try out the code in branch: https://github.com/crankyoldgit/IRremoteESP8266/tree/Trotec3550 and let me know how it goes for you.

It's only basic support (simple send & receive) of a state array at present. I'll add the detailed support later for individual settings etc

X-Ref: #1507 .

Mhh, I´m not excat sure how I should test it? Send the TurnOnTrotecAC.ino in e.g. Wemos D1 with IR-LED and let it run ?

[crankyoldgit]

A simplistic approach to testing it:

1. Download/clone the latest copy of branch https://github.com/crankyoldgit/IRremoteESP8266/tree/Trotec3550
2. Depending on your build environment, replace the existing library with the new copy. e.g. https://github.com/crankyoldgit/IRremoteESP8266#manual-installation-for-windows
3. Build the IRrecvDumpV2 or V3 example code, and flash it to an ESP with an IR demodulator/receiver.
4. Test the program/library can detect your remote as a TROTEC_3550 protocol.
5. Record/write down the TROTEC_3550 state[9] lines for a given remote action that you want to replay.
6. Modify the IRsendDemo.ino example to include the new state[] line you collected, and use irsend.sendTrotec3550(state); to send the message. e.g. like the existing samsungState/sendSamsungAC() lines in the example code.
7. See if your A/C responds.

Or .. replace the copy of the library inside Tasmota's source with the one from this branch, and and rebuild Tasmota.

Note: This doesn't give you the ability to set temperatures like other protocols ... yet.

Meanwhile I downloaded ../tree/Trotec3550.zip and replaced older IRremoteESP libraries and load TurnOnTrotecAC to a Wemos D1 and a IR LED via NPN Transistor. I see IR LED via Handy Video Mode working, and YTR IR Bridge receives something, but the A/C is not turning on.

Meanwhile I downloaded ../tree/Trotec3550.zip and replaced older IRremoteESP libraries and load TurnOnTrotecAC to a Wemos D1 and a IR LED via NPN Transistor

TurnOnTrotecAC is using the TROTEC protocol, not the new TROTEC_3550 protocol. i.e. It will not work at all, nor is it expected too.

As for Tasmota, you'll need to compile the "full IR" version with that branch for it to work. (if you want help using/building Tasmota, you'll need to talk to them. Not here)
The standard Tasmota build supports only a small handful of IR protocols by default. Trotec certainly isn't one of them.

[cool-lox]

Now I´m confused, I thought all of this will helps to bring in Model Pac 3550, here as a second device in Trotec section.
https://github.com/crankyoldgit/IRremoteESP8266/blob/master/SupportedProtocols.md
And can be later used also via Tasmota with IRhvac {"Vendor":"Trotec", "Model": "Pac 3550", "Power":"On","Mode":"Hot","FanSpeed":3,"Temp":22.5} for example.

Now I´m confused, I thought all of this will helps to bring in Model Pac 3550, here as a second device in Trotec section.

Sadly, the settings bit locations, and protocol timings are so different from the existing TROTEC protocol, it is easiest to implement it as a new protocol. About the only significant thing that's the same is the number of bits in the message.

And can be later used also via Tasmota with IRhvac {"Vendor":"Trotec", "Model": "Pac 3550", "Power":"On","Mode":"Hot","FanSpeed":3,"Temp":22.5} for example.

You will be able to use it sort of like that soon. Except {"Vendor":"Trotec_3550", "Model": "-1", etc etc}

Excellent. Thanks for that. That means the basic decoding for the protocol is working as expected. I can now move on to adding detailed control, like adjusting settings.

I still need you to check you can transmit with sendTrotec_3550() so we know that part is working too.

[crankyoldgit]

I've just added a commit to that branch that adds detailed support based on the data/spreadsheet you've provided.

There are still aspects of your spreadsheet and analysis that are not clear or incomplete.
One of the things I need from you is a full sequence of temperatures when you've set the remote to Fahrenheit.

Please download and test it. This version should give you the support you want via Tasmota, if you build against this library.

Let me know what works, doesn't work, or is missing etc.

Note: We shouldn't need rawData[] from now on, just the state[] lines and the text descriptions.
