@bhepler, is there a way to find out if/what module might be the cause of the extensive CPU usage? Other than the default modules, I only got MMM-Netatmo and MMM-ResRobot.

Hi,
I have a working MM and it looks amazing :smiling_face_with_open_mouth:
The only issue is that the CPU usage of electron(s) is extremely high.

I have followed everything in the Raspberry-pi guide but when running top I get the following:

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
  941 pi        20   0  400560 159456  78664 R 127.8 16.8   5:00.29 electron
  938 pi        20   0  312916  86456  70300 R  88.9  9.1   3:42.10 electron
  903 pi        20   0  487216 118084  77744 R  11.1 12.4   0:37.83 electron

Why so many instances of electron and why is the CPU usage so high? (by the way my SD card is fine and pretty much empty)

Any help would be much appreciated
