Tuya thermostat shows wrong temperatures

[Houri93]

The problem

Installed latest version of home assistant, added my Tuya account integration and my two thermostats show the wrong temperatures.

Smart thermostat purchase from https://www.amazon.co.uk/gp/product/B08G4YCTM9/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

also they show "Heat/Cool" mode, they don't have cooling though.

in reality, my smart life application and the device's screen shows that the thermostat temp is set to 18.0c and the sensor temp is 18.5c.

also Amazon Alexa seems to show the temps correctly.

Sam here. Temp in the HA = Real temp / 5

Nelle vecchie versioni di HA si poteva correggere il bug con qualche riga di codice .yaml.

Same here, I reported this issue year ago, and it hasn't been resolved.

I'm also using a Tuya thermostat (Moes from Amazon) with the same symptoms. current_temperature and the temperature setpoint are both divide by 5, (e.g. thermostat display & SmartLife show 20.0, HA shows 4.0). The tuya developer portal shows 40.

I'm guessing that HA is scaling the value from Tuya cloud stuff by 10 instead of 2 based on the observations, but I'm not actually certain how all of this works.
