      Java is by far the winner in using the most cpu and the most memory... hope that helps...

        same here.. see the top output below

        in my case I use an orangepi running armbian, the receiver also directly attached to the GPIO header. SInce i use mysgw as a deamon, the CPU usage is higher (therefor runs hotter), compared to an arduino with the sensor attached...

        But you are right java seems a bit memory hungry...

        Let me know if you need more info

            @Tag This is my RPI CPU usage, I use RPI minimal install and WiFI MySnesors gateway(two gateways)

              I have had to reboot the pi today a few times but am now monitoring memory usage. So far it is rising steadily, but slowly. I will give it a few days and see how it goes.

                I unfortunately cannot get the graph you show.....
                did you get it from a script or from the myagent software?

                  How do I add an image to a post here?

                  Also, what memory is mcagent reporting? Ram? Sdcard? I have an image screenshot that you might like to see!

                    @Tag Yes, I use MCAgent to report RPI internals.

                    @skywatch It is CPU of the RPI.

                    How do I add an image to a post here?

                    Just save the image on your local computer and do upload with upload icon when composing message on this forum.

                      @skywatch It is CPU of the RPI.

                      That doesn't make sense, memory is separate to CPU surely?

                      I can only upload images less then 512kb. At that level all detail is lost, can I send directly to your email?

                        @skywatch Yes, I put 512KB limit to avoid storage full. Yes please send to jkandasa at gmail dot com
