Tuya Thermostate On/Off Switch missing - Custom Switch Q

Hi @all, i use Thermostates which connected with TUYA

Issue i have is that this kind of Thermostates only have 4 Value i can use

  • Heat/Cool (=Power On)
  • Off
  • Temperature Room
  • Set Temperature

Is their a Way to color a Switch when is set “Heat/Cool”, when yes how?

Idea is following:

  • Thermostate has Cool / Heat as Switch and behind initiates Automations
  • Automation Heat: set HVAC to Heat, wait to 40° Out, Power On Thermostate,
    wait to achieve Room Temperature 24°, Power Off, Keep HVAC Heat solong not all Thermostates achieved their Temp
  • Automation Cool: set HCAV Cool, wait Temp Out <19°, Power On Thermostate, wait 3h, Power Off Thermostate and keep HCAV on solong Temperature is achieved to Thermostate defined Temp
