      Hello Everyone,
      I am quite new user here and I would like to ask you for some advise. I have some problems with %CPU and temperature (70-75C)
      Platform: RPi 3B+
      Electron: v3.1.13
      MM: v2.10.1
      Cooling: only Al heat sink (no fan)

      Please find below nmon screenshots:

      Do you have any ideas how can I solve my problem. I checked previous discussions but information there is quite old:

      I hope you have some solutions for those problems;)

            I guess too many 3rd party modules ;/ I will try to look for the one that causes problems.

              Please discard my previous post. Here is some more detailed testing:
              final

              It looks like ‘Weather or Not’ and ‘DarkSky’ forecast cause some problems. I will try to play with update interval.

              Anyway, like in here: old discussion, my %CPU with default modules look a bit higher than the one presented in old post.

              Do you think that electron version has some influence?
              Could someone else present own %CPU with default modules?

                @Ebson said in RPi 3B+ / high %CPU / high temp:

                'Weather or Not’

                CPU usage and heat have arisen now and again. If you search the forum you’ll find lots to read and perhaps a solution. At times it has been the version of Pi and other times the version of electron.

                Concerning MMM-WeatherOrNot: There are only 2 things that I can think of that might affect your Pi negatively.

                1. An extremely low updateInternal. The default is updateInterval: 10 * 60 * 1000, (10 minutes)

                2. The use of the animated icons option.

                I would like to hear from others if they are having the same issue, whether with a low updateInterval or the animated icons.

                  I used:

                  • Weather or Not:
                    updateInterval: 60 * 60 * 1000,
                    icons: Climacons (no animation)
                  • DarkSky:
                    useAnimatedIcons: false,
                    animateMainIconOnly: false,
                    updateInterval: 60,
                    requestDelay: 1000,
                    updateFadeSpeed: 2000
                  • 2x Newsfeed:
                    reloadInterval: 10*60*1000,
                    updateInterval: 15000,
                    animationSpeed: 0

                  and I ended up with:
                  finnnnnnn
                  I still need to consider adding fan but increasing intervals and turning off animation helped a lot
                  Maybe I will play also with some older electrons.

                  Thank you for your reply;)

                    Honestly, I don’t think a 60 minute updateInterval is necessary for WeatherOrNot.

                    DarkSky updateInterval is 60 ms??? (I don’t use that module). If that is miiliseconds it would certainly cause trouble.

                      You are right. I will change it into 6h… or even longer.
                      There is written in DarkSky’s Documentation that the value should be given in minutes. I don’t really know how to check whether it is not a mistake in Doc. I will make some testing;)

                        DarkSky:

                          setInterval(function() {
                            self.getData();
                          }, self.config.updateInterval * 60 * 1000); //convert to milliseconds
                        

                        So, value should be given in minutes in config file. Anyway, I will increase a value. BTW, it is also nice module for weather.
