Resido - the app for honeywell smart thermostats - requires notifications to be enabled to view or manage your thermostat settings or run time history. This is relatively recent because I had disabled notifications over a year ago due to it pushing ads to me.
The good news is you can limit it to only showing badges, but you have to at least have that enabled or it just freezes on a blank screen after telling you to edit your settings.
What an awful app too. It doesn't refresh the current temperature without force-quitting and restarting. Not as bad as my water heater app though. Couldn't get it to pair after 30 mins of headbanging, finally got through to their support who told me that the app usually doesn't work and they don't know why, and that I shouldn't bother trying.
It was annoying because my previous house had some z-wave enabled thermostats I could manage through the alarm system without any of that BS, I thought the honeywell in this rental would be nicer but all it's done is confirm I'll be using something other than honeywell controls in my next house.
