I’m involved in ChaCo, a cohousing project in Leeds scheduled for completion in summer 2019. I was alerted to your EmonPi product by people from the Carbon Coop and proceeded, via Leeds Community Energy to install my own EmonPi. As documented on Twitter I was very impressed with the results, which I’ve made available to the world, and more importantly my house mates, via a live feed (thanks for the feedback - finally I’m taking up your suggestion of asking questions on your excellent forum).
The question is: what would you recommend for logging the electricity use and PV production for a medium sized (30 house) co-housing project in which we are the energy supplier to households via a private wire? This is a broad question I know but it can be broken-down:
- Can EmonPi legally be used for billing?
- What are the relative strengths of replacing vs working parallel with a standard meter?
- If we go with an EmonPi-type set-up with 10 second readings how would you recommend setting-up a project-wide database of houses for ‘autobilling’ purposes?
Many thanks for an amazing product, good documentation and seemingly a slick community forum.
