If you want to use the thermostat remotely through the Vine app, you will need a dedicated Wi-Fi network at the residence to connect and register it.

The only way to register your Vine thermostat is through the Vine app installation process. Once you’ve connected and registered the thermostat to your account, you will then be able to operate it through the Vine app.  However, you can always operate the thermostat from the wall unit, and that does not require Wi-Fi.
