@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.
