If thermostat is turned off for some reason all hell breaks loose

[privatesam]

Thanks so much for this component. I have one big problem in production though. If a thermostat is offline -like switched off completely with no power to it - huge errors in the logs, slowdown on whole system and devices not responding etc - as soon as I take the component out of the config everything works fine. If the device comes back up all is fine.

Is there a possiblity to add something to ping the device and if its not up ignore it completely until HA is restarted?

Can confirm this for me. Home Assistant is unresponsive for 10 seconds, and responsive for 50 seconds again, then for 10 seconds unresponsive etc.
No error in the logs.
