If the IHD is on, but not showing any data, it could be because of one of these reasons: It's too far from your smart meter. Bring it within 15 metres of the smart meter (with no walls between). Switch it off for a minute or 2, then switch it back on again.

Why is my smart meter monitor not working?

If your smart energy monitor stops working check your power cable is inserted correctly and that your power supply is switched on at the wall. If it's still not working, try using batteries. If batteries fix the issue, then the problem is with the cable.

How do I reconnect my smart meter to IHD?

Try moving your In-Home Display closer to your electricity smart meter. Once you're there, turn it off using the round, flat button at the back. Wait a minute and then press the button again to switch the IHD back on. Sometimes, this gives it the boost it needs to get going again.
