Sense hat causing pi to run hot

Support

Running sense hat on pi 3 using python
As soon as python executes import sense_hat the processor speed monitor on the desktop jumps from 2-3% to 75% and stays there until python is exited (when it drops back to 2-3%. This occurs from the command line as well as in a program.

In some instances the temperature warning indicator comes on as well and the pi feels very hot.

It appears importing the module is activating a background process even though no deliberate python program is running.

Any ideas?

I’ve not noticed this before, but it could be related to the Joystick polling loop. Your best bet is to raise an issue on the GitHub repository, where the original authors/maintainers of the Python library may be able to shed some light on it: https://github.com/RPi-Distro/python-sense-hat/issues
