PIR sensor to turn on LED strip

[Egnos]

Hello everybody,
I am moving forward with my MM project and was wondering if it would be possible to activate an LED strip when the PIR sensor detects motion.

In particular, I use the following modules for the PIR:
MMM-GPIO-Notifications: https://github.com/Tom-Hirschberger/MMM-GPIO-Notifications
MMM-Screen-Powersave-Notification: https://github.com/Tom-Hirschberger/MMM-Screen-Powersave-Notification

Is there a module capable of controlling an LED strip using notifications?
Perhaps using the notifications of the module “MMM-GPIO-Notifications” …

Thank you all.

@Egnos from the 3rd party modules list, maybe

This module https://github.com/idoodler/MMM-RPI-LED it seems it cannot be controlled with notifications.

@Egnos that could be added pretty easily.

The problem is that I don’t have the skills to program. I understand something … but not enough … unfortunately

[sdetweil]

@Egnos well, there ARE people who could do it…

@Egnos what actions would u like the LEDs to do on notification? and what would u think the notification ID string should be?

Initially it would be enough to turn on the LEDs at the same time as the monitor is turned on and turn them off when the monitor is turned off.

For the notification I believe that the module that manages the LEDs should respond to a notification such as “LightOn-White” and “LightOff-White” generated by the module that manages the PIR sensor variations.
I hope I haven’t said too many wrong things … 🤞

@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.

[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'

[sdetweil]

@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
