Platformio is, IMHO, well worth having a look at. The libraries used can be stored with the code so no more problems from updated libraries breaking the code in the future. Anyway, work in progress but it's here and working on a wemos lolin32 board should anyone want to have a play. Probably inefficient as I tend to cut and paste then fiddle til it works rather than actually be a clever coder Smile

Thanks for this, I will give it a bash tomorrow :-) I was thinking about trying PlatformIo but the install seemed a bit complicated to me but I’ll crack it eventually.

Is this using the onboard shunt (0.01) or the boat shunt you mentioned further up?

Sorry for me being a clampit* but is:

High side - positive measuring
Low side -  negative measuring?

(*glaswegian name for numpty)

Thanks! :-)

I think high side is between the load and positive while low side is between the load and neg. As it's measuring current I don't think it matters - AKAIK it's just measuring the voltage drop across the built in 0.1Ohm resister, I just tried this and the current was the same both times.

Platformio is worth a little time, it was easy to add on to visual studio code. https://docs.platformio.org/en/latest/ide/vscode.html
Will probably save more time with spotting code which doesn't work as you go along instead of waiting for the compiler to return an error message like the arduino IDE does.


Having borrowed a section of your code (the MQTT part) and put a new calibration section in the Adafruit_INA219 library to take a larger shunt (in this case a 100a, 75mV one) and modified the “getcurrent” code that comes with the Arduino library, I have managed to get a ESP8266 recording Volts and Current via MQTT into OP and then giving me SignalK values [emoji16]

Thanks for all the pointers PaddyB and co [emoji1303][emoji1303][emoji1303]
