Existing Wyze Thermostat setup for heat, adding CAC tomorrow

How do I get back to that initial setup wizard to identify what the thermostat is controlling?
Options I can think of:

  1. Factory reset
  2. Delete device and add it again
  3. All of the above

I am using Android app.

Which is the shortest path to success?

I would both factory reset it & delete from app, then re-add it
