core: Tuya Platform Thermostat gives wrong temperature

This is still an issue in 108.x It is a native integration, we should not need to muck around with patches in reality.
I have found both values doubled. Current Temp and Set Temp both exactly double what it should be.
I have only tested with Celsius, I do not have a thermostat for Farenheit.
I am not good with coding, but open for any testing if someone can have a look at this? I don’t have many Tuya based devices, but I would be happier to have this fixed than to try and muck around with custom_components or custom firmware.

Thanks all

Hi all!

i’m also have the same isuue with thermostat: BHT-002GBLW with two sensors (internal for room temperatur and floor sensor).

I’ve checked this solution also: https://community.home-assistant.io/t/smart-life-tuya-show-wrong-temperature/89093/2

but as i see it does not fit in case i need to use two sensors, because in this case divide temperature by 2 in tuya.py will return average temperature between floor and room (they definitely will be different).

so i’ve tried to understand if there is two separate attributes returned from Tuya?

To do it i have executed http request with postman as it done in code here: https://github.com/PaulAnnekov/tuyaha/blob/66b1ff762597b7f70fd85a3f57cbfdb15b39e22f/tuyaha/tuyaapi.py#L151 (it makes post request to this URL: https://px1.tuyaeu.com/homeassistant/skill)

As we can see there is only one temperature current_temperature = 48 which seems to be sum of temperatures from two sensors.

Do you have any idea if it is possible to get two separate temperatures for both sensors as i Tuya mobile application?

@WRLPDZ , for me flashing https://github.com/fashberg/WThermostatBeca was the only way make Tuya thermostats controllable by HA.

@austwhite what board version of bht-002gblw did you do this to and how.? You say ‘an alternative firmware’ which was that? Thx

I did use Klaus’s Firmware on one device and used Tuya convert to flash it and it reported all temperatures properly.
Unfortunately a dodgy update (my fault) bricked the ESP on the unit and I was stuck with a dumb thermostat again. Got to be careful with updates. I have learnt a lesson from that one. If it aint broke, don’t flash it 😃

It has been suggested that the two sensors are added together making it double. I disagree. It is simply returning double the room air sensor. It is not retrieving the floor sensor at all. I assert this because in the app my sensors are not showing the same values: 24c & 15c currently, tuya returning 48c.

me too
