Great question, Gary, and thanks for sharing it with us!
We definitely agree that an open API (Application program interface, for those not in the know), for our customers to access their smart meter data, is a brilliant idea. This is something we have thought about, and plan on making available in the future, so watch this space!
The possibilities for community projects are endless and we'd love to see some of the ideas that you OVO Forum users have - fire away in the comments sections below! ;)
