PIR sensor to turn on LED strip

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

@Egnos Just in case…
Im using ioBroker @home (thats a free Smart Home Software). WIth that i also have installed MQTT. Any other Smart Home software like Home Assist can do the same.
I also installed Hyperion on the same Raspyberry i have installed MagicMirror. Inside ioBroker iam using the Hyperion adapter.
So with any “user_presence” i get the MQTT informartion… and that triggers a scipt inside ioBroker to activate Hyperion.

If your using any smart home software as well… this should be an easy thing. Feel free to ask…

@OberfragGER thanks for the valuable advice and for your availability, now I’ll read something.

In the meantime, can you tell me an LED strip (not necessarily RGB …) that is compatible with this project?

Thank you all.

@Egnos I have to add… i use also the Module https://github.com/olexs/MMM-UserPresenceToMQTT

For the LED-Strip… i use a WS2812. Its adessable an u can use it with 5V and it preconfigured in Hyperion.

Where did you buy the LED strip? They seem very expensive …

I have seen the connection between RPI and LED strip but I do not understand why the external 5V power supply must also be connected to the RPI, is it not enough to connect it to the LED strip?

If I really have to connect the power supply to the RPI as well, how do you do if you have both PINs of the 5V GPIO occupied?

I found these https://a.aliexpress.com/_EwF3KTV.
The WS2813 strip is 5V.
Can be fine?
