[OpenTRV-dev] OpenTRV to EmonCMS, via Node-RED (was OpenTRV boards)

[Damon Hart-Davis]

Hi,

We have the current Java-based RPi-friendly concentrator that Bruno and I are running.

We intend to extend that under launchpad to a more grown-up solution.

We are developing over the next few days (and I may be too busy to answer any more stuff on the list until we’re done) a light-weight half-concentrator / relay that you did the board for Bo (REV10).
