Looking more deeply in the forums, it seems that the need for a new emonHub node configuration for the emonPi_CM software has been found before by others, who have gone down the same path as I have -
and has been solved with the help of @Robert.Wall .
It seems that the node configuration that I used is not correct, and should be -
[[5]]
nodename = emonpi
[[[rx]]]
names = Msg, power1,power2,power1pluspower2,vrms,t1,t2,t3,t4,t5,t6,pulse1count,pulse2count,E1,E2
datacodes = L, h, h, h, h, h, h, h, h, h, h, L, L, l, l
scales = 1, 1,1,1, 0.01, 0.01,0.01,0.01,0.01,0.01,0.01, 1, 1, 1,1
units = n,W,W,W,V,C,C,C,C,C,C,p,p,Wh,Wh
which has a ‘n’ unit for the Msg data. It also has a nodename of emonpi, so the the original emonpi feeds do not have to be renamed. I have corrected my node configuration to suit.
It would be good if this information could be put into the documentation.
The measurement feeds from the emonPi are updating correctly in emonCMS, while data on the emonPi LCD display is still incorrect, and a comparison shows -
Data LCD Display feed
Power 1: --- (three dashes) 0
Power 2: --- (three dashes) 0
Vrms: 0 253.5
Pulse 300 0
Temp 1: 253.5 19.75
Temp 2: 19.75 300
So some of the data is there in the LCD display, but in the wrong places. Does emonPiLCD.py need updating or am I doing something wrong?
