Thanks Could you explain the overflow value a bit more ? All the circuits I have seen do not have any resistors (at least for the V+ input) and I'm only measuring 9 or 12 volts where as the INA219 says it does up to 26 (or 32 volts depending of which specs you read) eg http://www.ti.com/lit/an/sboa1...

Thanks TD-er I was wondering what the pads on the IDA219 were and read about bridging the pads to set the address. Thanks for suggesting the pull down resistors. I also worked out that R120 I was using is a old ESPeasy version and the main page does not really mention the new mega versions (I've dow...

Hi Olleman re the quote below Well, for now I have one wemos mini and two INA219s sending me voltages from my two batteries every minute via a mobile hotspot in the boat. Overkill but fun :) Im learning as a esp newbie, could you post how you run two INA219 on the one WeMos board and / or post the c...
