PIR sensor to turn on LED strip

[sdetweil]

@Egnos that led module can only on/off/ or blink

At the moment I could be satisfied … but it does not seem that the module proposed by you can receive notifications.

@Egnos notifications are easy… but this module rpi-leds, only toggles the leds ON the pi board… not led strip…

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

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

It appears to respond to notifications:

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

[sdetweil]

@Egnos it has a way for all off. but not all on.

@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
