No worries.
For SMETS2, there is no SIM Card in either meter - both meters actually communicate with the Comms Hub that lives above the electric meter and that Comms Hub does the rest, including communicating with your supplier via DCC. This is similar to SMETS1 but more powerful and arguably more reliable in general.
@
BigmacTom I'd say your electric meter has either temporarily lost connection, or has completely dropped off the Home Area Network. This would need further investigation and is sadly beyond what I'm capable of doing here. I'll ask @
PeterT_EONNext to see if he can flag this up for you.
@
gadget2001 I'll be brutally honest about this... You have the worlds worst In-Home Display ever, the IHDL SmartView 2. This issue will just be the start of many others you
WILL encounter with it. You may want to consider getting a more reliable one and chuck that existing one in the recycling bin - most electronics retailers would be happy to recycle it for you, but make sure to call E.On first to have it unpaired from your site. As for replacements, I'd recommend either the
ivie Bud or
Hildebrand Glow - make sure to get the SMETS2 variant if you go for the latter.
As for your issue right now, I can try to diagnose that for you. Please show me photos of your meters, similar to how @
BigmacTom did his. I especially need to know what kind of Comms Hub you have so that I can run through the right type of diagnostics.
