Viessmann heatpump electricity consumption values frozen

[fishter]

The problem

There are a few sensors in my device entry that get "stuck". The electricity consumption measurements called "DHW electricity consumption today", "Electricity consumption total today" and "Heating electricity consumption today". Around 1 am the measurement stops increasing despite the heatpump continuing to consume electricity. After rebooting the communications module of the VitoCal (via the ViCare app), the values become live again. The value is correct and I can see that the consumption is still being measured during the "freeze", but it's not getting reported.

I've tried the wifi on/off automation trick, but this didn't seem to have an effect.

Other values from the heatpump are generated normally throughout the period.

Diagnostic data is attached.

This is a known issue and you are able to workaround by resetting the outside world connection of the gateway (restart, disable wifi) in the night.

Please get help in the other issue. Just to be sure, the consumption continues to update in the ViCare app, right? It's just broken in HA.
