      Hi,

      Running 0.0.3-final on a rpi3 and seeing around 80% memory usage. I can't see how to add a screenshot or I would ! - Is this normal? Seems high to me.....

        @skywatch This is seems high.

        What type of gateway are you using? Are you running any script?

          Using mysensors gateway 2.2.0 - NRF24L01+ attached directly to the pi.
          If I reboot the pi then memory is about 53%, but gradually climbs over time (memory hole?)....
          No scripts running as far as I know.
          UPDATE - MQTT is running for the rpi internal info (that's how I know about the memory use- 88% now).
          I also notice that the rpi-gpio node is shown as down, yet has recently been active. I have nothing using that yet, so maybe that is the problem (but I would have expected it to be up and running after install, no?).

            @skywatch Can you check with top which uses more CPU?

              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.

                              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?
