Climate thermostat heating

Creating a home assistant climate thermostat for the heating

Current state: existing but not finally bug free...

  • status_sensor='calculations.ID_WEB_WP_BZ_akt',
  • current_temperature_sensor=Select a sensor from ha!,

  • target_temperature_sensor_write=not existing in luxtronik - only internal in this thermostat,
  • heater_sensor='parameters.ID_Ba_Hz_akt'
• Translation
• ClimateExtraAttributes
  • parameters.ID_Einst_WK_akt?

I have been toying around with a simulated alpha innotec rbe thermostat, moving the heating curve up or down based on the room temperature through ID_Einst_WK_akt

[tetsuo55]

Thinking about a bit more.

We should have a stable heat curve after a 2 or 3 winter seasons, idk if we should ever move the heat curve points at all with the thermostat, that then means we can only adjust it up or down by 3, degrees, if there is not thermostat connected to the heatpump an external one will have to be provided

I just deleted the heating thermostat from my dashboards. Other than the one for domestic water, there is not one value to go for. Heating curve is too complex, I don't want the thermostat to play with that.

The only think I can imagine right now is to use some kind of virtual temperature sensor. We could use living room temperature (for example) as exemplary value. In the thermostat you set a target temperature. If this is not reached, the temperature correction could be adjusted?

I will try to implement a heating thermostat as discussed in another thread:

So we can only control the thermostat via "parameters.ID_Einst_WK_akt" That means:
Is this how you imagine it to work?

Yes, exactly.

• let user define a correction_factorce.g. 100%
• calculate temperature adjustment = 0.5
• write this adjustment to "parameters.ID_Einst_WK_akt"
• this calculation should be repeated regularly, because the room temperature may change over time

The hvac mode (parameters.ID_Ba_Hz_akt) and preset mode (parameters.ID_Ba_Hz_akt) must be written from ha to luxtronik and read from luxtronik to ha.

Does anyone have experience with parameter 33 ID_Einst_RFVEinb_akt "remote control" = "Smart"?
