Just to raise awareness we have noticed that when iHost (ver 2.5.1) re-connects after creating a backup all TRVZBs (ver 1.3.0) paired with the iHost are switched to “Auto” Thermostat mode regardless of which Thermostat mode they were in prior to creating the backup. Although we have advised Sonoff about this we wouldn’t really categorise this as a bug/ fault as now we know about it we have accommodated for it in our back up process procedures.
