Advanced Fritz Thermostat

A library for setting the values AHA requests won't let you!

For basic settings use Heikos (hthiery) amazing pyfritzhome!

This library will always be hacky and will never leave the "beta state", since it uses undocumented API's. I use this library myself and I give my best to keep it updated.

But with any FritzOS upgrade this library might stop working, don't uses this if you can't live with that!

Remember: I'm doing this for free as a hobby, so be nice!

Requirements

• Python 3.12.0 or higher

Tested configurations

Device	Tested in FritzOS
FRITZ!DECT 301	7.60

If you have a different device or FritzOS version set experimental=True this will disable all checks, but beware there might be dragons!

Setup

Install using pip:

pip install fritz-advanced-thermostat

You will also need to setup a user.

Homeassistant integration

You can integrate this library as a HACS AppDaemon App. For installation and configuration checkout: mietzen/fritz-advanced-thermostat-hacs

Example Usage in Python

from fritz_advanced_thermostat import FritzAdvancedThermostat
from fritz_advanced_thermostat import FritzAdvancedThermostatError

host = '192.168.178.1'
user = 'my-user'
password = 'my-password'

try:
    fat = FritzAdvancedThermostat(host, user, password, ssl_verify=False, experimental=False)

    print('Available thermostats:')
    devices = fat.get_thermostats()
    for dev in devices:
        print('Device name: ' + dev)

    device_name = next(iter(devices))  # Get the first device name
    current_offset = fat.get_thermostat_offset(device_name)
    print(f'Current offset of {device_name}: {current_offset}')

    fat.set_thermostat_offset(device_name, current_offset + 1)
    fat.commit()

    new_offset = fat.get_thermostat_offset(device_name, force_reload=True)
    print(f'New offset of {device_name}: {new_offset}')

except FritzAdvancedThermostatError as err:
    print('An error occurred, check the logs!')
    print(err)
