Thermostat temperature wrong by factor of 10
I have a heated mirror (DMS SIH-600, shows up as "heater device (wifi)") wich shows up and works but the values are wrong by a factor of 10. On/Off switch works as expected. The Input in Homekit App allows values between 0°C and 370°C. wich seems to reflect the max temp of the device of 37°C. Dialing in 168°C results in a setting of 16°C.
The current temperature shown seems to be always 122,0°C. The Logs show:
`[27/07/2022, 10:12:05] [homebridge-tuya-platform] This plugin generated a warning from the characteristic 'Current Temperature': characteristic was supplied illegal value: number 190 exceeded maximum of 122. See https://homebridge.io/w/JtMGR for more info.
` 
Where 190 seems to reflect the 19°C shown in the Tuya app.

**Expected behavior**
I would expect a temp range from 0°C to 37°C as in the Tuya app. And the current Temperature reflecting the actual value instead of showing 122°C all the time, even when the heater is off.
