ViCare Integration: Not all available data is available inside Home Assistant

[noseshimself]

The problem

"In general every vicare system seems to be a unicorn 🦄. By now, we just try to map the devices that are in the api by type. Hybrids are not considered. So if the api show the devices as an own unit you should see it."

The diagnostic file shows that all relevant information pertaining to all heat sources is provided via ViCare API.

See attached configuration file: https://api.viessmann.com/iot/v1/features/installations/#######/gateways/################/devices/0/features/heating.burners returns an array consisting of one burner and is offering related data (burner starts...) and https://api.viessmann.com/iot/v1/features/installations/#######/gateways/################/devices/0/features/heating.compressors is listing all the heat pumps (and I know at least one installation with three different heat pumps shown there...).

It would be nice to retrieve https://api.viessmann.com/iot/v1/features/installations/#######/gateways/################/devices/0/features/device.messages.errors.raw even if it only logged (although a text sensor "last_error" would be even more helpful).

The data points are leaving me speechless. It seems to be possible to request that individual heating circuits can be used for individual heating modes (e.g. "heating is optional in winter" --> set the heat pump to dhwAndHeating but the burners to dhw whatever this is good for) using the API. It might be worth adding plausibility checks across the data returned. [Yes -- I used the ViCare integration to diagnose what happened when my heating did not react too well to being set to "fixed".]

Unfortunately, your diagnostics show only one device that has nearly every feature. This is not implemented in the vicare library https://github.com/openviess/PyViCare.

Please open an issue there first, so we can implement some kind of hybrid device. I will close the issue till that is done.
