Smart meter lights
The red flashing light next to the keypad (known as the metrology light) measures the electricity going through your meter.
The 3 lights above the screen, from left to right, are:
Power light - should be off (it only comes on when first installed, or when the energy’s back on after a power cut)
WAN light - measures communication with OVO. This should flash 5 times, then pause for 1 second
- HAN light - indicates the home network is open. This should be off.
Flashing WAN and metrology lights are good indicators that your meter’s working.
