Honeywell Total Connect Comfort constantly loses contact

I have the Honeywell TCC integration in my setup. I have successfully set it up, however, after a few hours or a couple of days, it stops communicating with the thermostat (and Honeywell servers). I have to do a full restart of HA to get it to work again, but the issue persists. Someone in another thread suggested adding a second admin account to the Honeywell service and dedicate it as the HA access, but that didn’t seem to make a difference. Anyone else run into this or have a fix?

This had been a problem since moving the Honeywell integration config to the UI a couple of releases back. A fix was put in place 2010.10, which works for the most part, but there have been a few who still see the problem but perhaps for other reasons which are being looked at.

Here is the (closed) PR on this if you’re interested:

Thanks for the link, glad to know I’m not the only one struggling with this. I have certainly had the issue continue since 10.0.
