"No Signal" message when PIR sensor is triggered



  • The MMM-PIRSensor is working perfectly. Unfortunately when the sensor times out due to no presents detected I get a blue screen with “No Signal” on my monitor/screen. Here’s my config:

     {
    		module: 'MMM-PIR-Sensor', 
    		position: "top_center", // Remove this line to avoid having an visible indicator
    		config: {
    			sensorPin: 22,
    			powerSaving: true,
    			powerSavingDelay: 10, // Turn HDMI OFF after 60 seconds of no motion, until motion is detected again
    			preventHDMITimeout: 1, // Turn HDMI ON and OFF again every 4 minutes when power saving, to avoid LCD/TV timeout
    			supportCEC: true, 
    			presenceIndicator: "fa-eye", // Customizing the indicator
    			presenceOffIndicator: "fa-eye", // Customizing the indicator
    			presenceIndicatorColor: "#f51d16", // Customizing the indicator
    			presenceOffIndicatorColor: "#2b271c" // Customizing the indicator
    		}
    		},
    

    I have enabled HDMI CEC on my monitor. I just want it to go dark. any suggestions?
    Thanks in advance!!



  • @steverichab don’t know the answer, but when u paste config or code, please use the code block,

    after pasting the text, select it, and hit the </> button above the editor to wrap the text



  • @steverichab oh, and my TV does the same… the HDMI is turned off at the PI, so the tv shows no input



  • Thanks Sam, As you can tell I’m a newbie but I really appreciate the coaching!

    Is there a way to simple trigger a black screen saver via the PIRSensor module? really anything but a blue “No Signal” message.



  • @steverichab with mmm-remotecontrol you can “hide” all modules. So you will get a clear black screen without “no signal” message.



  • @Serge said in “No Signal” message when PIR sensor is triggered:

    mmm-remotecontrol

    Thank You Serge, not sure how to hide when the PIR sensor module is triggered. I will start to work on it.



  • @steverichab Wow Serg, My head exploded while trying to get the the MMM-Remote-Control module to “hide” just the calendar module when triggered by the MMM-PIRSensor module. Could you show or point me to an example of these two modules getting rid of this “no signal” problem.
    Thanks!

    I have the same issue, and I am sure there was a time I got the monitor turned off directly with another module.
    I think there are different ways of turning the monitor off, at least for more recent Raspberry Pis and this module might be using the wrong one for us.
    I wanted to look into this more, you motivated me again :-).



  • @lavolp3 Thanks, I hope you come up with something. As I said the frame is functioning perfectly except for the “no signal” problem. The MMM-Remote-Control module is tempting but I was not able to figure out how to “hide” everything when the PIR sensor triggered.

    @steverichab Hi, there are other PIR modules that support hiding out of the box like MMM-NewPIR or mine MMM-Screen-Powersave-Notification.
    My module needs my GPIO module to get triggered. You ca find a complete example here
