Look on the underside, if it is a hard wired thermostat there will be a screw.
- If it is a neoStat WIFI, there will be a WIFI sticker near the screw. You will not need a neoHub to have App control.
- If there is no WIFI sticker, it will be one of the neoStat V2 series. You would only be able to have App access with a neoHub.
