I want to use multiple temp sensors in various rooms to control Keen vents as well as averaged for the main Thermostat (Ecobee), but since most temp sensors are battery powered, they have very low rates of reporting, e.g. 30 minutes.
Some sensors can be set to report more often, but is the trade off for quick response, .e..g 1 minute, too great in terms of battery life.
What are people doing here, finding wall powered temp sensors, or letting the HVAC overshoot with long response times?
I've been doing Z-Wave since 2014 with a RazberryPI board, migrated to HE this year.
I have a rule when HVAC is in heating or cooling thermostat operating state to refresh my sensors every 10 minutes.
1 minute seems unnecessarily frequent. I would try 10 minutes and see if that works well.
Can your temperature sensors be configured to report whenever the temperature changes by a certain amount? If so, something around a half degree F would likely work well.
What you want here are updates based on temp changes, not interval reports.
When I was developing keenect I was having temp sensors report on 0.2F changes, this was more than sufficient.
Most if not all the Hubitat zigbee drivers include threshold reporting down to .25F
