Unexpected error in worker for App schedy_heating (TimeoutError with traceback)

[flecmart]

Hi there,

I used schedy for a long time now without any problems. Lately I noticed that my thermostats don't switch the way I scheduled them with schedy anymore... I looked in the AppDaemon Logs and found the following schedy warning. This happens sporadic I think since I updated to 2021.05. Does anymone encouter the same or can figure something out with the traceback? If I restart AppDaemon schedy starts working somehwo again... but it reacts somehow slow and will crach again sporadically.

I am experiencing the same problems - do you have got any solution? I already thinking of finding an alternative to schedy...

[flecmart]

I tried to debug it for multiple days and did not find a solution. I reimplemented my heating stuff with node-red... it is a completely different approach but I am happy how it turned out.

[Julius112]

Hopefully, I don't need to go down that route as well...
Thanks anyway for the update :)

I went down that route and switched to: https://github.com/nielsfaber/scheduler-component
For anyone who is interested I'm happy to write a little bit more about on how I archived a similar behaviour to schedy.
