How to Fix / Troubleshooting

Safety first: Isolate mains before moving the HubR if it is hard-wired.

Reposition HubR: Move the Wiser HubR to a more central location in the property, away from metal objects and large appliances.
Add repeaters: Install additional mains-powered Wiser devices (e.g. smart plugs or room thermostats) to strengthen the Zigbee mesh.
Avoid metal enclosures: Do not install TRVs inside metal radiator covers or behind thick metal grills.
Rebuild network: After moving devices, allow time for the Zigbee mesh to rebuild, or power-cycle devices to encourage new routes.

Thermostat or Wiser app reports very low signal strength to certain TRVs or room thermostats.
