Can I have multiple Sensi thermostats registered to my Sensi account?

Yes. You can have multiple thermostats at multiple locations registered to a single account. Once you install, connect and register each one, you will be able to control each thermostat individually from the Sensi app. You can see a snapshot of each thermostat from the main page of the Sensi app. If you select one, you can edit the settings and schedule for that particular thermostat.
