Notification only when error occurs, notification usability tweaks
A setting to hide all the mundane "going to home mode", "going to away mode" notifications is desired; the remaining notifications should only occur when an error occurs i.e. - some registered devices haven't reported geolocation so keeping thermostat in home mode. Cause of unknown device geolocation often is due to login credentials being lost after an app update, or physical device having been swapped out for another (AppleCare replacement) and Skylark not being installed/credentialed/configured/newdeviceregistered/olddevicedeleted with Skylark service.
Also, when ALL device geolocation informations aren't known, the notification should be changed from "~thermostat staying in home mode since a device is still at home" and instead say "~thermostat staying in home mode since location of all registered devices is not known". This change would help the user realize when a device is really at home versus when Skylark is just playing it safe because some devices aren't reporting location.
