Cannot initialize communication with INA219 (output). Error message: Could not determine default I2C bus for platform.

No info on log folder.

should need install extra packages?

[frtz13]

just a guess: try to add the busnum parameter in line 626, to make it look like:
inaRPi = INA219(0.00725, busnum=DEVICE_BUS, address=0x40)
can't check it myself (currently away from home).
if ok, the same in line 635.
