I2C ids are wrong in status 10 output

[Khurram]

I have 2 INA219 connected to an ESP32 running 15.3.0 (custom compiled). After setting GPIO22 to I2C SCL and GPIO21 to I2C SDA and restarting the ESP32, I run i2cscan and I get the following output:

I2CScan
"Device(s) found on bus1 at 0x40 0x44"

But running the Status 10 command gives the following output:

{"StatusSNS":{"Time":"2026-04-18T00:48:04","INA219-1":{"Id":40,"Voltage":14.3,"Current":-0.034,"Power":-0.5},"INA219-2":{"Id":41,"Voltage":14.3,"Current":1.296,"Power":18.5}}}

The status 10 output is showing 1 device with id 41. This is very strange.

Just to be on the safe side, I would try with a stock bin. If it's the same. It may be that the initial scan put them into different i2c channels and then allowed the same channel to be used.

I tried with the stock firmware but the behavior is the same. The 2nd INA219 has id 44 which is correctly identified by i2cscan. But "Status 10" output shows the id as 41 for the 2nd INA219. I think the INA219 driver is just assuming the ids in sequence which is not always the case.
