[Feature] Add verification of updated settings

[hllhll]

It might be a good idea to add some watchdog to notify the user whenever a command was not applied by the AC,
for instance, if the AC is stuck and the user want to change something the AC will not respond with an updated message. The integration can pick this up and notify the user.
