Your Smart Energy Display (SED)

Some quick checks
Our handy checks might help – but only if your Smart meter was installed more than 10 days ago as it takes a little while for the device to be updated with your details.
Make sure your device is plugged into a permanent source of supply.
Check the location of your device – it should ideally be within 10 meters of your Smart meter.
Restart your device by pressing and holding the power button.
Does my SED have to be plugged in?
My SED says ‘connection lost’, ‘awaiting data’ or ‘incorrect tariff’ what should I do?
This could be because the SED has been moved.
Try moving it back to it's original position or as close as you can to the electricity meter and then switch it off and back on again.
My display has gone blank and isn’t showing any data even though it’s plugged in.
If it is, try switching your SED off, then back on and see if this reconnects the SED back to the meter.
If it has moved since the install place it back to the original position or as close as possible to the electricity meter and see if this reconnects the SED back to the meter.
If you’ve already tried to turn your device on and off again and moved it closed to the meter and there’s no change, please get in touch.
My display isn't up to date.
What do I do if I think my energy usage isn’t accurate?
