Since HA 2023.11.* every integration can use its own server file storage folder which is backuped with the HA backup.
Perhaps we should automaticly create a json file of all heatpump params or or diag file dump every day in it.
We can create a list of all relevant config params ("whitelist" or a all sensors excluded by "blacklist"). Normal operation params like counter, operation modes, current target temps have to be excluded.
Or create a delta file with changed config params.
The restore method reads the relevant config params from a selected file and writes it as dump into the heatpump.
Perhaps firmware files can also stored automaticly in this folder to allow downgrades.
