Simple to use and very handy Unfortunately it now on regular basis is unable to connect with WiFi. Unreliable connection yet all the other items I have on WiFi have no connection issues After quick response and guidelines it seems to be back on track. 26/02/2022 WiFi issues have come back with a vengeance,it seems that this issue is not going away and is only WiFi appliance I have issues with. Regret buying this Nest thermostat
