Did the Ecobee Premium end up working out for your with Shabbas? Did you put foil to disable sensor? I just bought one myself and would be interested in hearing a follow-up. Thank you
Nothing worked have. My display is always on.
I just set up an Ecobee Premium. After fiddling with it, I seem to have Standby mode totally disabled so that the screen is just always on as if you just woke it up. This seems perfectly fine to me.
Of course the device is always detecting presence, and in theory you can see in the app whether it detected someone. But I'm not sure if that is such a big deal as long as you don't open your phone on Shabbos. It was easy to turn off all the smart features based on the presence sensors.
