MMM-DHT-Sensors

This an extension for the MagicMirror.

The intention is to access DHT11/DHT22 sensors directly within MM without any cronjobs and submitted data via textfiles or stdout/stdin. Both temperature and humidity are displayed onscreen.

Requirements

The BCM2835 library is required on your raspberry pi.

node-dht-sensor is required as well.

Installation

Open a terminal session on your raspberry pi. No matter if you are using ssh or if you access your pi directly.

First of all you need to install the BCM2835 library, in case you don't have it. Just follow the instructions below or look at the libraries website to find the most recent version and updated installation instructions.

# download the sources
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.50.tar.gz
# extract the archive
tar zxvf bcm2835-1.50.tar.gz
cd bcm2835-1.50
# compile and install the library
./configure
make
sudo make check
sudo make install

Afterwards we can install the MagicMirror Module. Navigate to your MagicMirror's modules folder using cd ~/MagicMirror/modules and execute git clone https://github.com/yawnsde/MMM-DHT-Sensors.git, a new folder called MMM-DHT-Sensors will be created. Change into the new folder with cd MMM-DHT-Sensors and run npm install to install dependencies. Now please change into the subfolder using cd node_modules/node-dht-sensor and run the command below:

npm rebuild --runtime=electron --target=1.3.4 --disturl=https://atom.io/download/atom-shell --abi=49

This was done to avoid any version errors.

Last step before we can use the module is to add our user to the GPIO security group.

sudo adduser -g $USER gpio

Usage

WORK IN PROGRESS!
