My older Ecobee installed a major firmware update last spring without asking, and it changed many of the display settings on it. The update also turned off the heat when it rebooted and didn't turn it back on. If we were away and it was a bit colder, we might have arrived home to frozen pipes!

We don't use any of the energy "saving" features on the Ecobee, and rarely adjust it remotely. I only installed it because I was mad at the thermostat that came with our house, which would fail to turn on the heat whenever its AA batteries died with no warning. My next thermostat will probably be a Z-Wave unit by Honeywell or someone else, with a local Z-Wave radio connection to my Home Assistant server for monitoring/control.....
