so, I’ve had the visit from the engineer. In summary I’m connected, I have an updated gas tariff but not yet an electric one. I’m going to wait for 24 hrs to see if the electric tariff updates appear.
the solution was to reboot the meter first the electric one then the gas one. Then wait 6 minutes for the electric meter to completely power off. Turn on the electric meter, wait for all the lights to flash then power on the gas meter then pair the two meters.
if only there were a simple button on the outside to do this. But, to power off the security tags come off and the big fuse is pulled.
anyhow. I’m 50% there, I’ll check the powe tarifff and the updated usage tomorrow
