Hello friends
yesterday I connected it like this
now like this
the current field reacts like yesterday 0.0000 A
if i add or subtract it sets a fixed value (without sensor data)
if I multiply or differentiate I get 0.00000

Re: INA219 Calibrate external shunt
i test without shunt the formula field works. Can shift the decimal places, for example.
with shunt I always get 0,00000
can it be that the plugin does not count with 4 digits behind the decimal point?

Re: INA219 Calibrate external shunt
Thank you very much TD-er for your explanation.
I was able to calibrate the voltage across the formula field
The current field doesn't seem to work. Or I'm doing something wrong no matter what I enter the value goes to 0,000

Re: INA219 Calibrate external shunt
many thanks ThomasB I have already read this posts. in my version (mega-20200410) i can also do that set measuring range. Screenshot_14.png it is possible to calibrate the resistance with my version EspEasy ? or do I have to use a sketch? how do i do it or can i do it with a formula? (https://www.le...

INA219 Calibrate external shunt
Hello everybody I am brand new here in the forum. And find Espeasy a nice thing. Unfortunately, I do not have to find any understandable solution to include a certain shunt over the INA219 in order to measure larger loads. Unfortunately I haven't quite got that with the calibration of the new resist...
