Hi Paul.
There's a thread
elsewhere on the forumwhere folk with Greenwave people are saying it's working natively without my plugin.
However I have one myself which I don't think is... I think the sockets don't map correctly to the reports.
I've asked folk to confirm the current status of theirs then I can work out what's happening.
I can certainly support them in the plugin once I work out what's happening for different users and (I think) firmware versions - I have the 5-node UK version myself.
The other thing to note with Greenwave is that it won't report a value when you ask it to if it's recently sent one, so you can't reliably just refresh the data on a 5-minute schedule for example.
