I think it would be helpful if there is a place for people to show case their install. I am a fan of Unifi, and they display it like this: https://community.ubnt.com/t5/custom/page/page-id/Stories. I see you also have a show case under EmonCMS>Showcase, but slightly different. For instance I found a story here Full-fat 3-phase monitor | Archived Forum Which was useful. I think have a prominent place when we go to the community / forum would help!
Have to say I just signed up yesterday, but I thought that would be really cool to have seen different setups from people in one place. And I guess, like most of us, are usually very happy to show your own work once it is finished and give others ideas how to set it up, especially from those who set up many of these!
Just a thought.
