Smart meter

PAB190968

Is there any way of me being able to fix a SMETS2 electricity meter which doesn’t communicate with the hub that sits right above it? I have found the HAN in the display menu but how do I get it to connect? HAN and WAN are both fine (green lights flash every 5 secs). Gas meter connects fine. Photo attached

What makes you think that there is no communication between the electricity meter and the hub? These are the lights that should be flashing on the comms hub.

What do the indicators mean on a SMETS 2 Comms Hub?

The comms hub sits on top of the SMETS (Smart Meter Equipment Technical Specifications) electrcity meter and has a series of LED indicators showing the functional status of the metering system. Each LED has a legend shown below:

SW

This shows the status of the hub's software. You should see a green light flashing every five seconds.

WAN

Shows your communication hub's ability to communicate with your supplier. If your meter is connected, you'll see a green light flashing every five seconds. This light may be off if your meter is using the MESH network to communicate.

MESH

This light may be on if your meter is connected and communicating through another network (this network has been built to allow more meters to communicate in areas with poor or no signal).

HAN

This light shows the connection status of your electricity meter, gas meter and/or IHD with your communications hub on the HAN (Home Area Network). If connected, you'll see a green light that flashes every five seconds.

GAS

This light tells you if a gas meter is connected; you should see a green light flashing every five seconds. If you don't have a gas meter installed, this light will be off.

As far as I know, it is a hard connection between the electricity meter and the communications hub. The gas meter connects to the communications hub via the HAN as does the IHD. Electricity and gas data is sent to the supplier via the WAN not the HAN.

If the supplier is not able to pull data from the meter then it can be down to a meter firmware issue. Meter manufacturers are responsible for firmware updates. Last year it took Kaifa 7 months to resolve a firmware issue on one of its meters. You can check data flow by signing up to the App BRIGHT. Your supplier can also ask the DCC (the network operator) to carryout a remote reset of the communications hub.

It could also be an EDF problem. Suppliers use secure software to connect to the DCC Network (known as an Adapter), this can cause issues.

In sum, only your supplier can resolve this problem for you.

Both WAN and HAN green lights flash every 5 seconds but only the gas data goes to EDF and the IHD. EDF just ignore my complaints so guess I’m stuck with a not Smart meter.

I was EDF for a couple of months after a supplier failure. My smart meters were fully operational in the sense that the supplier could pull data from them until the moment that EDF took over. When I switched away to Octopus two months later, the meters mysteriously came back to life! I could see data flows on BRIGHT app throughout my time with EDF so there wasn't a smart meter issue.
