UPM Invalid Argument: Temperature: mraa_aio_init() failed, invalid pin?

[trajkd]

I’m getting

Traceback (most recent call last):
File "/usr/src/app/grovetemp.py", line 28, in <module>
temp = upm.Temperature(0)
File "/usr/local/lib/python2.7/site-packages/upm/pyupm_temperature.py", line 106, in __init__
this = _pyupm_temperature.new_Temperature(pin, scale, r0, b)
UPM Invalid Argument: Temperature: mraa_aio_init() failed, invalid pin?

even though I have:

from upm import pyupm_temperature as upm
temp = upm.Temperature(0)

in temperature.py and I’ve connected the sensor to A0. What might be going on?

The board is an Intel Edison Arduino with the Grove Temperature v1.1 sensor.

The Intel Edison board is running balena OS.
