I have two hats a PiJuice UPS and a SenseHat. The GPIO pinouts for each are https://pinout.xyz/pinout/pijuice and https://pinout.xyz/pinout/sense_hat respectively.

When I stack my SenseHat onto the PiJuice and try it out in Python the SenseHat is not seen, with Python issuing the error below

>>> from sense_hat import SenseHat
>>> sense = SenseHat()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/sense_hat/sense_hat.py", line 39, in __init__
    raise OSError('Cannot detect %s device' % self.SENSE_HAT_FB_NAME)
OSError: Cannot detect RPi-Sense FB device

Both hats work fine separately. So am I right that there is a conflict in how they use the GPIO pins? Or is there another reason?

TIA

Nick
