These LED indicators are on the Communications Hub, bolted on top of your electricity smart meter.
The left LED displays information about the power status and the Wide Area Network. As you’re in the Northern Territory, the WAN signals are picked up by a network of 70 masts operated by Arqiva.
The right LED gives the status of the Home Area Network. This links to your In-Home Display (IHD) and gas meter (if present).
Under normal operating conditions, both LEDs provide a green flash once every 5 seconds. This is called the Slow Frequency.
Which LED is red?
Is it flashing once every 2 seconds (Medium frequency), or faster?
Here are the three possible frequency patterns for a fault. But as you’re in the Northern Territory, they will flash red, not green:
If your meter lights are flashing more frequently than every 5 seconds or are solidly on, we’d advise carrying out a smart meter health check for your meter type below and contacting our Support Team with the results:

There [is] one red light flashing on my smart meter
I can’t see that this was covered by
The red lamp flashes at a rate governed by the meter constant shown beside it, here 1000 impulses per kWh. If there is not much power being used, it will flash infrequently. Switch the kettle on to see it flashing about once a second. This is how the meter measures how much energy you’re using: it just counts each Wh passing through it.
If you count the number n of flashes in a minute, the formula connecting the frequency of flashes to the power draw in kW (the load, L) for a meter like this with a meter constant of 1000 is L = 0.06n.
