After this, the integration is "dead" and won't pass any values to the controller or receive any updates. I have to restart HA to get it working again. This seems to be happening about once a week for me.

Do you still have that issue? I don’t have much of a way to work on it currently but I can try to help if you need me.

I get that error all the time! I also get this one:
Logger: custom_components.intellicenter.pyintellicenter.controller
Source: custom_components/intellicenter/pyintellicenter/controller.py:480
Integration: Pentair IntelliCenter (documentation, issues)
First occurred: February 5, 2022, 6:00:22 PM (38 occurrences)
Last logged: 9:36:54 AM

cannot start: [Errno 113] Connect call failed ('192.168.0.181', 6681)

Both of those errors render the integration dead. Most of the time I can reload the integration and that will fix it, but occasionally I have to fully restart HA to get everything back.
