Your Chameleon 3 in-home display
The Chameleon 3 in-home display works with your smart Pay As You Go meter to help you keep an eye on your energy use and costs.

Tips to get the most out of your smart meter
Keep an eye on your energy
Try taking the in-house display around the house and turning different appliances on and off to see how this changes the amount of energy you're using.
Don't leave your appliances on standby
Research by uSwitch shows that we waste £227 million a year by leaving appliances on standby. That includes TVs, set top boxes and phone chargers.
Stay connected to your in-home display
Don't hide your in-home display. Leave it where you can see it easily, and as close as possible to the smart meter to make sure you have a strong connection.
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 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.
