4 years ago I found the time to dump my states database and see how often my thermostats changed their value. In general, I found the lowest time (when changes happen most often) to be around 1 minute - actually pretty spot on.
There are two outliers - one which has an update after 25s - this is a room I often check on, so I think by pressing the thermostat, it triggers an update which would explain the low time.
The other outlier, 2mins at its lowest, is a room in the middle of the house with a solid heating arrangement - so its temperature might not swing as much .. It might also be that when a room is not heating, that the thermostat reports back more rarely.

Just occurred to me. HA will auto-poll every 30 seconds by default. I'm not sure which frequency the thermostats are running in, but we could match it (its likely a lot more than 30s). This would save requests from HA.. :)
