Another progress update.
Robert Wall developed a new set of firmwares for the EmonTx v3 and emonPi, published last year (see forum post here). I’ve adapted these firmwares to run on the EmonTx4 and emonPi2 providing continuous monitoring + native RFM69 radio support on the new hardware and uploaded the firmwares to the emonTx4 and emonPi2 github repositories. There is also a short guide in each repository on setting up the Arduino IDE, downloading the right libraries and setting the compilation settings.
See the guide for the emonPi2 here

and the guide for the emonTx4 here:

The OLED display firmware for the emonPi2 is coming together nicely. Here’s a picture of it running on one of the RFM69Pi boards I mentioned above. You can do much more than this with these display’s of course but it can at least do the same as the original emonPi LCD so far.

We have also been building up more systems for ongoing development and testing.
We are still waiting on another quote for the EmonTx4 and emonVS manufacture and will hopefully update on that soon.
