Scale String-Value for HVAC

Hello World,

currently I started fresh to work with home assistant for the first time.

For my appartment I have bought following HVAC products:

BHT-002-GBLW → For single frame
https://smart-life24.de/produktwelt/wlan-smart-raumthermostat-sl06116w/ → For multiframe

I also installed HACS, tuya local and this plugin:

After all the BHT-002 works well.

The SL06116W is different, here “current temperature” and “target temperature” are scaled 10 times.

I expect the vale 21.5 and get 215.

Is there a possibility to setup or to fix in code?
