Hello Tim,
I think this is an excellent suggestion.
It would be great to group people together by whatever affinity/location and be able to track aggregated data.
It could also give extra value. Imagine that you’re in a group where everyone has a 4kWp PV system. Your output could be monitored and you receive an alert if your production drops below the average of others in the group consistently.
After more searching, I see the Groups Module New Emoncms Groups/Administration module which may do exactly what you’re looking for.
A better link (to the github module with description) is GitHub - emoncms/group: In development: Emoncms groups module
Best regards /Colm
