As there appears to be a considerable amount of interest in getting an emonTx unit running Robin’s MK2 code (calypso_rae on this forum) and communicating with emonGLCD / emon Base … I thought it was about time I publish where I am at with my project.
The emonTx with CT1 connected to the Grid, and CT3 connected to the Solar PV generation meter, AC psu and 5v USB supply are also connected.

So many thanks to Robin for the MK2 code, Ian for the Calibration code, Glyn and Trystan for the building blocks as well as Paul Reed, Stuart and Robert Wall who have all made major contributions via this forum and get us to where we are today.
