Certain data no longer available via API

[firewiremb]

I have been using PyViCare for a long time. Until recently I used version 2.28.1. Since I noticed that the error PyViCareNotSupportedFeatureError('getHoursLoadClass1') was occurring in my log files, I carried out an update. I suspected that the API had changed and this might be fixed with a newer version.

After the update to version 2.32.0, not a single feature of the API was available anymore.

I was able to find out that version 2.31.0 is the last version that works for my circumstances. (The PyViCareNotSupportedFeatureError('getHoursLoadClass1') still occurs with this version.)

See also files in the appendix.

I guess you have a Opto1 connected? Viessmann changed their api that the gateway is the first device to return in the list. Also with v32 the opto1 is handled as a gateway class and not as a hearing device. Make sure you access your heating device instead.

Thank you for your quick reply.
Yes, I have connected a Vitoconnect 100 OPTO1 to my heat pump.

I changed:

device = vicare.devices[0]

to

device = vicare.devices[1]

This solved my Problem using v32.

The PyViCareNotSupportedFeatureError('getHoursLoadClass1') however still occurs.
The last day this feature was available and providing data according to my log files was October 9, 2023.
Has this feature been disabled within the Viessmann API or is something wrong with my code?

@firewiremb yes, it's likely that viessmann disabled that data for your device. It could be that it moved to the paid tier (no guarantees).

Out of curiosity, it could be that the values have just moved. Do those numbers fit your previous ones? @firewiremb

[firewiremb]

Thank you for inquiring again. No, unfortunately these are not the values I miss.
I found an older dump.json file that I created when the feature was still active. The values I'm missing are hoursLoadClassOne, ...Two, ...Three, ... and so on.

I suggest that you ask in the Viessmann community about the data point. The support may tell if they moved something.

I made a request in the Viessmann community:
