      He is from the stone age. He doesn’t know what a laser is. 😱

          Ha, ha :laughing:
          Will change my dependencies when I have some spare time.

          We're all stories in the end. Just make it a good one, eh?

            At first: Thank you very much.
            This module is great and works fine for me.
            When it’s allowed to make some suggestion…
            you maybe could add a possibility to switch wireless sockets.
            The effort for this shouldn’t be much, when you can use xkonni’s remote control.
            https://github.com/xkonni/raspberry-remote
            This would be a great possibity for those, who don’t feel comfortable to use a 230V relais… (I studied Mechatronics, so i don’t care :P)

                @paviro any suggestions on what relay to get for use with this? There are lots of choices on amazon

                  Ok. When I’ve time, I will get a wireless transmitter.
                  Would be embarrasing if it wouldnt work because I’ve never tried :anguished:

                    @paviro I finally found some time to look into the problem I had some more. The exact origin is still unclear to me, but I did figure out that my problem, it is not related to your module, or the MM software in general. I got the same behaviour over ssh: tvservice -o switches the monitor connected to the Pi off, tvservice -p switches it back on, but the screen would appear black. After fiddling around a little bit, I found another solution that does not require root rights. Instead of using the sudo chvt 7 && sudo chvt 9 command, the problem can also be solved using fbset. My modified version of the activateMonitor function file node_helper.js:

                    activateMonitor: function () {
                        if (this.config.relayPIN != false) {
                          gpio.digitalWrite(this.config.relayPIN, this.config.relayOnState)
                        }
                        else if (this.config.relayPIN == false){
                          exec("/opt/vc/bin/tvservice -p", null);
                          exec("/bin/fbset -depth 8 && /bin/fbset -depth 16 ", null);
                          exec("/usr/bin/xrefresh",null);
                        }
                    

                    For the command xrefresh to work when given via ssh, the correct display variable has to be set (in my case):
                    export DISPLAY=:0 I have added this line to my .profile file in the /home/pi directory so that I don’t have to type it every time I log in via ssh.

                      @MechMatt Have a look at the PowerSwitch Tail. If you live in the US, you can buy an assembled version from Adafruit. If you’re in 240V land (like me), you will have to do some (basic) soldering. Works like a charm for me. :-)

                        That’s really odd that you have to go through all of that. On my rPi-3 with the most recent Raspbian Jessie release, I can use 'tvservice -o' and 'tvservice -p' and it just works. I don’t have to do anything else. It’s all running as the unprivileged user 'pi' (and without issuing 'sudo' before each command.) I wonder if it has something to do with the monitor and what it responds with when a signal is sent … Glad you figured it out though.
