Accuracy of sensor.vicare_supply_temperature #341

Closed mho21git closed 6 months ago

mho21git commented 7 months ago

Hi all, the accuracy (precision, resolution) of sensor.vicare_supply_temperature is 1°C But I'm sure, it is provided and must be 0,1 °C heating.circuits.N.sensors.temperature.supply grafik

For me the sensors seem to work, but for some reason the default display accuracy is different.

I seem to recall a discussion on the Viessmann developer site, where people were mentioning that Viessmann have reduced the accuracy of the data that they provide through the API.

Yes this was my thread on the viessmann page, only available in german. https://www.viessmann-community.com/t5/The-Viessmann-API/Werte-der-API-ploetzlich-gerundet-geglaettet-bzw-nicht-mehr/td-p/237282

As @crazyfx1 mentioned, this is an active change made by Viessmann over a year ago. If you subscribe to the (pricy) subscription I have been told that you have higher granularity of the values. Nothing we can change from perspective of the library.
