@Maximo34 My guests do not have access to the thermostat. Since my HVAC system is 3 zones, I tell them on check-in to please keep me apprised if they get too warm or too cold, and I’d be more than happy to adjust. However, if you have only 1 zone, I don’t know. If 72-74 is comfortable enough for you, will that be comfortable enough for guest, especially during the summer months in AZ.
Also, I suggest not giving guest access. You could end up having an extremely large bill unless you can control minimum/maximum temperature on the Nest.
