@DocVooDoo Weird… did you follow all the instructions? ie, install bcm2835, npm install, etc?

@DocVooDoo sometimes the raspberry pi needs some time to pick up the values… try to increase the update time (ie, 30 seconds) and wait for it to update a couple of times…

@DocVooDoo Then I don’t know, maybe there is something wrong with the module…

Have you tried mine? https://github.com/ryck/MMM-DHT-Sensor

Description

I was looking for a nice and simple module to display the air quality index (AQI), but all the modules I found were not really updated, or not using an API, or you couldn’t have several instances of it, or were not international, etc, so… I created my own.

This module gets the Air Quality Index (AQI) using the World Air Quality Index project API.

@weeee99 Seems like the module is working… Have you tried to access the sensor directly? Look my previous post in this thread to know how to do it. Make sure that the pin in the correct one (GPIO and physical pins are not the same, so it can be a little bit confusing). Finally, the one I got (https://www.amazon.co.uk/gp/product/B01N6PB489/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) is plug directly to the Pi, no breadboard / resistance required…

@PaulB Thank you!

@PaulB Hi Paul

That happens sometime, it’s related to the way the raspberry pulls data from the sensor, but it should be OK on the next try. Just in case, put a quick updateInterval (like 1 * 60 *1000) and see what happens…

Also, you can try to get a read directly from the sensor, bypassing the MagicMirror. Just clone this (https://github.com/adafruit/Adafruit_Python_DHT) somewhere and edit and execute this (https://github.com/adafruit/Adafruit_Python_DHT/blob/master/examples/simpletest.py), ie, `python simpletest.py

Good luck!

@flo You mean the monitor model? I don’t know for sure, I think is a viewsonic, but I’ll try to get the model later…

But to be honest, anything will do the part, just get anything cheap and start from there :)

What you want here is a PIR sensor, so the monitor only wakes up when there is someone around. That will help you with the electric cost and, more importantly, won’t stress your display that much. Look for “PIR sensor” here, there is plenty on modules / ways to do it, and the actual sensor is dirty cheap on Amazon. If case that helps you, this is how I did it.

@cornusandu I don’t think a video will help you, you just need to follow the instructions here: https://github.com/deg0nz/MagicMirror-Display-Controller

Make sure you you set the path and the the pin variable to the correct values and that’s it.

A quick way to fix this:

cd modules/MMM-Buttons
npm install electron-rebuild
./node_modules/.bin/electron-rebuild

It always worked for me…

@MyMirror in the pir.py file you need to change only one thing, the GPIO data pin to which the PIR sensor is connected (you can double check yours here: https://pinout.xyz/). The line is this one: https://github.com/deg0nz/MagicMirror-Display-Controller/blob/master/pir.py#L8

That should be all.

The line 7 stuff is for the service (ie, run the script automatically every time the Pi reboots) and is in a different file: https://github.com/deg0nz/MagicMirror-Display-Controller/blob/master/pir_sensor.service#L7

@MyMirror I don’t get any text on the display when it goes off, maybe the display is smart enough? Are you using the same software to turn it off?

@TGBB Yeah, just two 40x50 RIBBA frames glued back to back…
Any reflective film will work. Seems like the link I posted is not valid anymore, but you could use something like this…

@MyMirror Sure, I’ll try tonight, but I can already tell you:

• The PIR is attached to the bottom of the frame with some bluetack
• The PIR sensor is using this “module” so just follow the instruction (ie, here)
• My frame was 40x50, but you have more options, just choose the one that works better for you (and fits your screen, of course)

Good luck!

@Ogret Sorry, I don’t have access to the mirror here, so I was waiting to get home today to reply to you. It’s just adding some code in the custom.css file with the right class, but seems like you already found how to do it!

Cheers,

@PaulB Did you follow all the steps? Without logs is a little bit difficult to know what’s going on… Did you try to check if the sensor is working (like with a python script or something). It sound like a config.js issue…

@Dracarys I am not seeing any update notification at all… Do you still have the issue?

@clubbi maybe you could implement this in a separate module, implementing sendNotification / notificationReceived ?

Version 1.3.0

• Fixes typo (app_key vs api_key) so now you won’t hit the API limit. Sorry about that. Thanks to flick116 for opening the issue.
