      @plumcraft strange, I’ve RPI 3 as well and I don’t see this problem … This may be related to which monitor/TV your RPI is connected.

        I assume too that the behaviour is different between TV’s. On my LG the screen turns blue with a big message of lost signal on HDMI after 10 seconds after the screen turns off. Not so nice - but then again, nobody should be in the room anyway…? ;-)

            @plumcraft Yeah there doesn’t seem to be an answer for the blank screen issue…

              I am sorry to hear about your issues. Trying to think of the best way to troubleshoot that. The module doesn’t do anything fancy. It just executes these in the node_helper to switch on/of the output on HDMI:

              Switch off:

              /opt/vc/bin/tvservice -o

              Switch-on:

              /opt/vc/bin/tvservice --preferred && sudo chvt 6 && sudo chvt 7

              As a first step, could you please try to execute these commands in the ssh terminal?

                  Ok, the next step let’s check whether the off state is detected correctly. After you switched off the monitor with the first command try to execute this in the ssh term:

                  /opt/vc/bin/tvservice -s

                  and let me know which output you see.

                    output is:
                    state 0x120002 [TV is off]

                      @trividar @cowboysdude paviro is also using the same code lines in his pir sensor module and a user had similar issues, maybe his solution also work for you

                      Please create a github issue if you need help, so I can keep track
