7 months ago I have found others that may be fighting the same issues, but perhaps its just an understanding issue of the underlying thermostat code somewhere where I am not setting the values correctly?
https://github.com/espressif/esp-matter/issues/773
Something like this would be where I would like to end up, but using matter for more universal access to home such as alexa/google/apple/etc.
https://developer.amazon.com/en-US/docs/alexa/device-apis/alexa-cooking-temperaturecontroller.html
The issues I am running into at the moment is that the thermostat device is severely crippled by Alexa with limits imposed of 36F to 95F. These appear to be hard coded in the alexa side as I can set the heat point to 212F on the code side, but the user can't adjust anything except turning down the temp until its below 95F.
Hoping we can add more of the newer device types to the models available that I can try to use such as the temperature cabinet, or many of the kitchen appliances (not sure if matter supports these yet or not). I tried using the temperature cabinet model that I found somewhere (cant find it now), but that device type was not found in this library.
I am working on a water kettle (boiler type device) where I need to be able to set and take actions within Alexa up to around 220F. Seems there are many new types of alexa devices that are well suited to my upcoming needs, just not sure how to get them to be usable thru the matter protocols.
