Vitocal 200 Compressor Phases (+Recreating the Sensor from the ViCare Home Assistant Integration)

[EarlSneedSinclair]

The Viessmann ViCare Home Assistant integration (link) provides a useful sensor for the compressor phase.

This sensor displays five different compressor states: off, preparing, heating, defrost, and pause.
In Home Assistant, these states need to be assembled using a template sensor. I will provide the template once the necessary datapoints are identified.

So far, I have found the following datapoints (poll list items) that deliver correct values for my Vitocal 200-S (204D/CU401B_S):

• Compressor heating or off:
  ("vd_status_betrieb", 0x0480, 1, 1, False) # WPR_RelaisZustand_Verdichter1
• Compressor defrost:
  ("vd_status_abtauen", 0xB446, 1, 1, False), # WPR3_B446_Ausgang_Abtauung

I am still looking for the preparing and pause states. These seem to be related to timers.

Does anyone have an idea which datapoints could represent these states?
