PIR sensor to turn on LED strip

sdetweil

@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 fixed the typo, git pull for the update

sdetweil

@MMRIZE good catch

sdetweil

@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 ! ;-)

@Egnos ok got it.

what I was saying is that the

MMM-PIR-???

modules, if you use them, THEY send the USER_PRESENCE notification

the GPIO_Notifcations module is more generic and can send notifications for ANY gpio device

Ok ok, I just wanted to be sure that, in my case, the MMM-GPIO-Notifications module sends the “USER_PRESENCE” notification.
I knew that the module I am using is a collector of GPIO devices…

Thanks @sdetweil
