KeyError: 'system_water_pressure' about mypyllant-component HOT 8 CLOSED

The first error should be fixed in the latest version, although I could not reproduce it.

The last error is only a info message, I've removed it from the latest release. Your system doesn't seem to report water pressure in the same way as mine, so the sensor goes to unknown. You could try turning on debug logging and looking through the logs for water pressure data: https://github.com/signalkraft/mypyllant-component#debugging

If you can find how your system reports this data, I may be able to add it.

Hi there

The major python error went away, but I still see this error
2023-04-10 13:10:30.422 INFO (MainThread) [myPyllant.models] Could not get water pressure from system control state

I turned debug on and can see the following being pulled back into the long JSON collection.

operational_data={'water_pressure': {'value': 1.1, 'unit': 'BAR', 'step_size': 0.1}},

Hope this helps.

For info, i'm running a 5kW Arotherm Plus heatpump with Sensocomfort indoor control.

Thanks for checking this out.

You may have better luck with the new release, I added a 2nd sensor for the water pressure data you are seeing.

Thanks for the update, that has resolved it!

Glad to hear that! Could you let me know the names of your Vaillant devices, so I can add you setup to the list of tested combinations?
