I have seen that #andybarrow asked the same question:
"How does one differentiate between the three channels of the INA3221?"
but I did not find the answer in the dialog following.
from ina.
The INA3221 shows up as 3 distinct devices. The "getShuntMicrovolts()" function only takes one parameter, so you would call it as
uint16_t in3211_1 = INA.getShuntMicroVolts(0);
uint16_t in3211_2 = INA.getShuntMicroVolts(1);
uint16_t in3211_2 = INA.getShuntMicroVolts(2);

Where die @andybarrow ask the question?

Thank you!
@andybarrow asked in closed issue #67.
Since you both seem to be interested in building BMS with INA chips, I am working on a networked battery reporting system based on INA chips, ESP8266 and thinger.io as dasboard server.
I mainly aim to build a software MPPT around plain buck converters targetting the very low-power domain, but the main code could be used for a BMS of any dimension as well.
The main feature is currently to be able to forward the battery information over the network to another ESP, so one could build a BMS for any voltage with an ESP per 12V block, overcoming the 26V limitation of the INA.

Stay tuned...

Very nice!
My battery bank is 24V which means it can hit 28.8V while charging so the standard breakout boards for the INA219 won't work for me. I want to monitor my solar panels separately, so the INA3221 is perfect for me so that I can save on components.
from ina.
INA226s could do (36V), but are limited to 24V nominal.
I suggest to use a network of several ESP8266s (one for each block of 12V + one to centralize the values) equiped with INA3221 to monitor each cell, to make a scalable solution, open ended to every voltage.
You have more devices (an ESP8266 costs nothing), but far less cables.
