    @sdetweil said in PIR sensor to turn on LED strip:

    but this module rpi-leds, only toggles the leds ON the pi board… not led strip…

    Maybe this module could fit https://github.com/jc21/MMM-PiLights, using SPI and a LPD8806 or WS2801 LED strip.

    @sdetweil said in PIR sensor to turn on LED strip:

    if u can find one that works the ed strip with a python command, then we can make that work

    It appears to respond to notifications:

    this.sendNotification('PILIGHTS_SEQUENCE', 'blue_pulse');

        @Egnos use my updated fork…

        https://github.com/sdetweil/MMM-PiLights

        it responds to the PIR modules USER_PRESENCE notification (true = turn on, false = turn off)

        if lights are off and on is sent, it will restore the previous sequence set with the normal
        SEQUENCE notification

          Hi,

          I would suggest the solution of @sdetweil as well.

          An other, but much more complicate version would be to use my PythonLedControl and control it with the MMM-MQTTbridge module.

            Thanks @sdetweil

            Let’s see if I understand:

            • By default the LEDs will be off, until the “MMM-GPIO-Notifications” module detects something.
            • If the PIR detects the movement the “MMM-GPIO-Notifications” module will send the notification USER_PRESENCE = true and the LEDs will turn on
            • After some time without movement the “MMM-GPIO-Notifications” module will send the notification USER_PRESENCE = false and the LEDs will turn off

            Correct?

            I’m not a developer, but I’m still trying to understand your change in the code:

            else if (notification === ' USER_PRESENCE'){
                        if(payload == false){
                            this.leds.allOFF();
                        } else {
                            // user present, restore the last active sequence
                            Promise.resolve(this.runSequence(this.lastSequence.sequence, thi,lastSequence.iterations,this.lastSequence.delay)
                            .catch((err) => {
                                this.log('user present Sequence error: ' + err.message);
                            }));
            

            why can’t I see this notification in the code?

            (notification === ' USER_PRESENCE'){
                        if(payload == true){
                            this.leds.allON();
                        }
            

            Thanks again!

              @Egnos
              ' USER_PRESENCE' !== 'USER_PRESENCE'

                    @Egnos u don’t need the GPIO_Notifications module. as the PIR modules send the USER_PRESENCE notification

                      The module I use for sending notifications when the PIR detects motion is MMM-GPIO-Notifications
                      I believe he is sending the “USER_PRESENCE” notification:

                      notifications: [
                                  {
                                    notification: 'USER_PRESENCE',
                                    payload: true
                                  },
                      

                      Thanks for your patience @sdetweil ! ;-)
