Have just hooked up an emonTx v3.2 with emonTX3CM and configured it with
w0 to turn off the radio and turn on serial.
Am getting the following output:
MSG:190,Vrms:251.72,P1:28,P2:539,E1:13,E2:265,pulse:1 MSG:191,Vrms:251.16,P1:29,P2:545,E1:13,E2:266,pulse:1 MSG:192,Vrms:250.98,P1:26,P2:523,E1:13,E2:268,pulse:1 MSG:193,Vrms:251.05,P1:23,P2:508,E1:13,E2:269,pulse:1 MSG:194,Vrms:250.27,P1:22,P2:495,E1:13,E2:270,pulse:1
A few things stand out here:
The voltage is really high. When I measure it with a multimeter, it jumps between 242V and 243V. I guess I need to calibrate it? - is it normal it’s that far out?
I have 2x clamps connected, but one is reporting only 22/23W - is there an explanation for that, or is it just a dodgy one?
Watching the output for a bit, there is the odd lines like this:
MSG:63,Vrms:251.75,P1:23,P2:489,E1:4,E2:87,pulse:1 MSG:64,Vr3,P2:488,E1:4,E2:89,pulse:1 MSG:65,Vrms:251.97,P1:24,P2:491,E1:4,E2:90,pulse:1 ... MSG:167,Vrms:251.46,P1:21,P2:491,E1:11,E2:232,pulse:1 MSG:168,V1.65,P1:23,P2:501,E1:11,E2:234,pulse:1 MSG:169,Vrms:251.73,P1:22,P2:498,E1:11,E2:235,pulse:1
Is that normal?
