Hey there, to answer your questions:
- It shouldn’t make any difference
- Yes and unfortunately yes, it’s best to start clean
- The temporary hold feature when enabled stops the app for overriding the user defined temperature for a duration of the current schedule. What you’re looking for as I understand is a permanent hold, i.e. hold until I say resume. Here is how you can do this, open the app, unselect the thermostat for which you want a permanent hold and tap
Save. We didn’t add a separate button for permanent hold due to limited screen space. This way it’s very flexible, you can still have some thermostats running on schedule while others are on permanent hold.
