      @rovarma said in Electron CPU usage:

      The solution is to use Raspbian Jessie for now and ignore Stretch until this is fixed in Electron.

      This has already been determined in the contents of this topic. The combination of Pi, OS and Electron versions for best performance is clearly stated above and has solved the CPU issue for many users since this topic started 3 months ago. :-)

        I gave up on MM2 last year because of how bad the transitions looked. Recently I had need of something like MM and decided to try again and had the same CPU load and terrible transitions until I found this thread.

        With the latest Raspbian Stretch, MM2, and a downgrade of electron to 1.4.15 it works far better. Barely a spike on the CPU meter.

        This thread is far too long. Considering the impact of this solution, it really should be in the FAQ on github. The only reason I even noticed this thread is due to the weekly Email summary.

          If it were shorter then the results may never have come to light and many other users like yourself may have given up due to the CPU issue

          Perhaps, but I have nothing to do with such things. I’m just an old dude that wanted to know what was causing the issue and with the help of some fine people I think we did just that. However, I do appreciate the recognition and thank you on behalf of everyone that participated in the testing.

            For anyone running into this issue, run the following command from your MagicMirror folder:

             npm install electron@1.4.15

              One more data point: The Pi behind my office mirror was doing okay, until I enabled the MMM-Snow module. Short version is that I had to downgrade Electron to 1.4.15 but now it’s running pretty well with 50 snowflakes.

                  @schlachtkreuzer6 I had the same error when I downgraded. However, it did install and I am able to run the Magic Mirror process. I am getting a temperature warning. I’ll experiment a bit to see if I can narrow that down.

                    @bhepler Yeah funny!
                    But you´re right. It install electron and the temperature sinks from 82-85°C to 52-55°C and the animations are smooth. Only the error massage is strange!

                      @schlachtkreuzer6 Technically, they’re not error messages. They’re warnings. If they become serious, then they will be promoted to errors.

                        @MichMich Got a similar issue as reported by @schlachtkreuzer6, unfortunately I now have a black screen when starting. Logs show “WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 50, got 54”. Any suggest on how to revert?

                        Update: Managed to successfully revert back but doing a " npm install electron".
