espeasy problem - ina219 - does not detect the voltage

[miki8989]

Hello
I have a problem on detection of voltage dell'ina219

The System And esp8266 12th and ina219 with espeasy R108
connected to nodemcu v2

I tried a wire on the positive Vin + 5v , on Vin- a resistor in series with a conduit connected to the negative

I see the device on the current VOLTAGE by the led but the voltage remains zero

I tried a load module for 4 ina219 but always Equal , a zero voltage

Solutions ?

Thank you
