Possible Causes
Heat HubR located in poor RF position, Too few Zigbee repeaters (Smart Plugs), Heavy interference from Wi‑Fi or building materials, Low batteries in thermostats or TRVs
How to Fix / Troubleshooting
Safety: No mains work required unless relocating Heat HubR (electrician only).
- Improve RF layout: Move the Heat HubR to a more central, open location if possible (qualified electrician).
- Add Smart Plugs: Install Wiser Smart Plugs in distant rooms to act as Zigbee repeaters.
- Replace low batteries: Ensure all battery-powered devices show good battery levels in the app.
- Reduce interference: Keep Wi‑Fi routers and other 2.4 GHz devices away from the Heat HubR.
Persistent offline issues despite good RF design may indicate a failing Zigbee radio in the Heat HubR, requiring replacement.
