Thermostat 2441TH not returning to prior state after power outage

[Andrewjb]

Hello. I have 5 thermostats in Heat mode. After a power outage ended, the thermostats were all off. Using the Insteon app on my phone, I put them all back into heat mode. I had to reset the temperature on each thermostat because the prior setting was not retained. My hub is on an uninterruptible power supply so it did not lose power during the outage.

I haven't dealt with many power outages and don't recall having to turn the thermostats back on and resetting the temperature.

Any advice for getting the thermostats to return to their prior state after a power outage would be greatly appreciated.

Thanks
