No it is not possible to add a neoStat WIFI to a neoHub. They will always appear as a separate location on the App.
To Change Location
- On the Home Screen
- Press the button with the two houses in the top left corner
- Then select the new location you wish to go to.
You can have multiple locations linked to the same Heatmiser Neo App.
Not sure if you have a neoStat WIFI?
