Chameleon 3 troubleshooting tips and advice

Why is my smart meter not connecting?

The more bars you see in the top left of the screen, the stronger the signal to your smart meter.

Move the display closer to the meter if you have a weak signal, or you see the 'connecting to smart meter' message.

How do I reset my smart meter in-home display?

You can reset your in-home display if you have connection issues, or if it stops updating.

Unplug it from the mains and hold down the power button on the back for five seconds. Wait one minute, reconnect to power and switch it on.

Can I unplug my in-home display?

We recommend that you always leave your in-home display plugged into the electricity mains.

Don't rely on the built-in rechargeable battery. It will only last for up to four hours between charges.
