Why has my Heatmiser neoHub stopped connecting to the app?
neoHub connectivity issues are usually caused by router changes, Wi-Fi dropouts, or a hub firmware update — most are fixed with a hub reboot or router reconnection.
Fixing neoHub Connection Issues
Common causes when your Heatmiser neoHub won't connect:
- Router changed or reset — the hub may need reconnecting to a new network name/password
- Wi-Fi signal issues — the hub is often installed near the boiler, which can be a weak Wi-Fi spot
- Firmware update in progress — wait 10–15 minutes and check again
- Power interruption — unplug the hub for 30 seconds and reconnect
When to Call an Engineer
If a reboot and router check don't resolve it, the hub may need reconfiguring or there could be a wiring fault. RARE engineers handle Heatmiser installation, troubleshooting and neoHub reconfiguration across London. Call 020 7458 4949.
