Updating of sensors sometimes stops working

This happened to me a few times. Basically, the sensors stop updating the only thing i found in the log is this:

Let me know if there is any other information i can provide.

It might be as simple as me catching the exception since the library should always try to reauthenticate if the token isn’t valid anymore. I think the exception is making home assistant not try to it update again. I also can probably add detection of intentional downtime to the library since I know how they tell the app about that. I think this is pretty fixable so I’ll try to take care of it next time I make updates to this (which will probably be soonish since I added support for their smart outlets to the library and want to add them to home assistant as well)

I’m doing some cleanup and am going to close this issue. Please open another if any new issues come up!
