Radiotherm thermostat: Update of climate.thermostat_76_b5_a4 is taking over 10 seconds

This seems to happen every couple of minutes, filling up my log. It’s within a few feet of my wireless hub. Running on a Rpi 3. I can still change the temperature on the thermostat, and it appears i have complete functionality. The warning, though, makes me a little nervous that things will stop working.

Any thoughts?

I’m seeing the same thing, but only with 1 of my (2) thermostats. WiFi signal strength shouldn’t be an issue.
