How the Heatmiser neoHub Works
The neoHub provides network connectivity for compatible Heatmiser neo heating devices.
The gateway connects to a broadband router through an Ethernet cable and communicates with the Heatmiser cloud server.
Once the gateway has been registered in the neoApp, compatible thermostats and other neo devices can be added to the system.
Connecting Heating Controls to the Home Network
The neoHub serves as the connection point between compatible Heatmiser heating controls and the home network.
The basic setup follows this sequence:
- Connect the neoHub to the broadband router.
- Connect its power adapter.
- Wait for the network and cloud connection indicators.
- Register or sign in to the Heatmiser neoApp.
- Add the neoHub as a location.
- Pair compatible neo heating devices.
- Complete the setup.
Remote Heating Control Through the neoApp
The Heatmiser neoApp provides the interface for registering the gateway and adding compatible heating devices.
The app allows the neoHub to be associated with an account and organized under a named location, such as Home.
Compatible neo thermostats can then be added as individually named zones.
Apple Home and Siri Integration
