Re: Imagine the meetings
They are separate comms units but SOP for any meter issue is to replace the entire thing.
One of the fitters told me that if they lose access to the comms network for over 24 hours they brick and have to be replaced. That may or may not be true but I went through 6 of them before they fitted one that worked..
The other issues is the comms units are specific to the brand of meter, and there are, well, I know there are at least 6.. how many more I couldn't tell.
Luckily here in the north it's not a mobile phone network but a dedicated one operated by arquiva, so there's no issue with 2G.
