What to do
The loss of information could be caused by either the distance of the in-home display from the electricity meter or interference.
The in-home display typically has a range of 20-30ft, interference will reduce this. It is recommended to move the in-home display closer to the meter so a stronger signal is received which would cause fewer dropouts of signal resulting in issues.
What to do
Step 1: If the in-home display has a power button on the back then hold this down until the in-home display is switched off completely.
Step 2: If you can't find a power button disconnect the in-home display from the power supply and remove the batteries (if you are able to) for 1 minute.
Step 3: Re-insert the batteries and reconnect the in-home display to the power supply.
Step 4: The in-home display will then attempt to connect to the Smart Meter(s).
* It can take up to 24 hours for the information with regards to usage to re appear. Historical information will not be lost by performing a hard reset.
