Yes, I’ve seen those since I installed HA in 2024. It’s on the Honeywell end, the connection site is slow at times. It never affected my thermostat, so I ignored them for a while until I filtered them out of the log, so I no longer see them.

Here’s the link where it was reported back then and the code owner replied:

You have to be careful to rate limit them harshly, like once or twice an hour if you have more than one.
