These steps come from Hive’s radiator valve offline article and its radiator valve factory reset guide.

What This Problem Means

A Hive Radiator Valve talks to your hub over Zigbee. Offline means the hub has lost contact with it, so the app can’t change its temperature or schedule. Hive says the valves “require the current version of Hive Hub or Hub 360”, and the original Hive Hub does not support them.

Common Symptoms

• The valve shows offline in the Hive app
• The valve’s screen stays blank when you wake it
• The radiator doesn’t follow its schedule
• The radiator stays warm when the valve is set to off

Safe Checks You Can Try

1. Wake the valve and check the batteries

Wake the valve. If the screen stays blank, fit new non-rechargeable alkaline batteries. It takes 2 x AA, and Hive’s Radiator Valve page says to “avoid using Lithium or rechargeable batteries as these can cause damage to the product.”

2. Remove and refit the batteries

If the screen works but the valve is still offline, take the batteries out and put them back in.

3. Restart the hub

Restart your Hive Hub and give it 5 to 10 minutes to come back, then refresh the app.

4. Switch on Hive lights and plugs

Make sure any Hive bulbs and Hive Plugs are switched on at the wall. Hive’s Signal Booster page says a Hive bulb or Hive Plug boosts the signal between your Hive devices.

5. Test it near the hub

Take the valve close to the hub, take one battery out and put it back, then wait 5 minutes to see whether it comes online.

6. Check your hub

Hive says the valves need the current Hive Hub or a Hub 360, and its hub article says the original Hive Hub does not support Hive Radiator Valves. Our Hive Hub lights guide explains the hub generations.

7. If the radiator stays warm when off

That’s a different fault. Hive’s radiator valve troubleshooting says to press the valve pin with a coin. If the pin sticks, wipe it and lubricate it with silicone, then refit the valve and check its orientation in Settings in the app.

When To Contact Support

If the valve still won’t reconnect after a factory reset and re-pair, contact Hive through its help centre.

Last resort: factory reset. If it’s still offline, Hive’s next step is a factory reset and re-pair, which erases the valve’s schedule and actions. To reset it: take the batteries out, hold the button under the display, put the batteries back while you keep holding, and keep holding for 5 seconds until all the segments on the screen light up. Then pair the valve to your hub again in the Hive app and set its schedule again.
