The final answer I received from Bulb said that the connectivity issue with my smart electricity meter would be remotely fixed. After this delay can I assume that this reboot was not successful or indeed hasn’t happened ?
Unfortunately, there are some issues that a reboot won’t fix. It looks like this is the case for your meter, and we just need to wait for the DCC to run a full fix for the error your meters hit. I’m really sorry about this.
