Electron CPU usage

@TheBogueRat said in Electron CPU usage:
This thread is far too long.
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
Considering the impact of this solution, it really should be in the FAQ on github.
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".

i have a problem at downgrading:
pi@magicmirror:~ $ cd ~/MagicMirror pi@magicmirror:~/MagicMirror $ npm install electron@1.4.15 > electron@1.4.15 postinstall /home/pi/MagicMirror/node_modules/electron > node install.js - @types/node@7.0.43 node_modules/@types/node magicmirror@2.1.3 /home/pi/MagicMirror └── electron@1.4.15 invalid
How can i fix that ?

Hey guys,
(first, sorry for my english. i hope you understand what i am trying to tell^^)
i have got the same problem as u all.
So i tried to fix it with using MagicMirror 2.1.0 and electron 1.4.15
Unfortunately i am not the best programer, so sometimes i don’t know if i’m doing anything right.
Well, i tried the option as shown in this thread on page 18 (https://forum.magicmirror.builders/post/28875)
That gave me some npm errors when i type “npm start”.
So i tried to use this guide: https://forum.magicmirror.builders/topic/5274/how-to-manually-install-mm-on-your-pi-for-absolute-beginnersBut it gave me the same errors.
Step by step i did:
- rename the original MM-Folder to “MagicMirror_OLD”
- Downloaded this https://github.com/MichMich/MagicMirror/archive/v2.1.0.zip
- extract it and rename it to “MagicMirror”
- cd in this folder and type “npm install”
- after installing was done i typed “npm start” and got this:
pi@MagicMirror:~ $ cd ~/MagicMirror/ pi@MagicMirror:~/MagicMirror $ npm start > magicmirror@2.1.0 start /home/pi/MagicMirror > electron js/electron.js npm ERR!

Please include the following file with any support request: npm ERR! /home/pi/MagicMirror/npm-debug.log pi@MagicMirror:~/MagicMirror $
Another time i tried as shown on page 18. it was showing me, that i was using electron 1.4.15, but when i typed the “npm start” it shows me the same message as above.
i don’t know what to do :( would be quite nice, if u guys could invest some time to solve my problem together. thank you very much :)
