Sounds like you’ve got a Landis+Gyr smart meter there. These were the smart meters often installed by British Gas alongside a Trilliant communications hub. As the SMETS 1 and SMETS 2 versions of these meter have the same model name, we’ve got a great guide to help you figure out whether your meter is SMETS1 or SMETS2.
If you have an SMETS1 version and have recently switched to OVO, these flashing lights could indicate that the smart meters aren’t currently in communication with us. We weren’t originally able to access the usage data from this type of S1 meter. There’s good news on the horizon though, all S1 meters are currently being remotely upgraded to make sure they can communicate with all suppliers much like S2 meters do. Landis+Gyr S1 meters are due to be upgraded by September 2022 - read more about this here.
In the meantime, check out this guide for help in taking your reading manually - You can submit these readings on the meter readings page of your online account or OVO app (download for Android or iOS).
Hope the meters are remotely upgraded soon so you can get back to enjoying the full benefits of going smart!

We had a brand new smart electricity meter (Landis&Gyr E470 TYpe 5533) fitted on Wednesday afternoon. It’s now Saturday evening, and it’s clocked 30 KWh, so it’s metering fine.
The Geo IHD is still trying to connect, though it’s less than 2ft away from the meter. And on the “comms box” on the meter, there are no lights showing at all - SW, WAN, MESH, HAN are all off, all the time.
I’ve read here that it can take up to 6 weeks for data to start showing on our account or in the OVO app - but if all the comms lights are out, how is the meter communicating at all?
