dht-express

A simple express webserver serving data of the DHT11/ DHT22 temperature and humidity sensors.

Installation

You need to install the Broadcom BCM 2835 libary first.

After that clone the repository.

git clone https://github.com/edjopato/dht-express.git
cd dht-express
npm install

If you want to include the endpoint in your existing Express webserver take a look in the topic at the end of the README

Configuration

Remember to configure the webserver in the standalone.js after the comment

// add more sensors on routes here
app.use( '/', sensor( 11, 4 ) );

You have to configure the express route, the sensor type (11 or 22 for DHT11/ 22) and the pin.

Run

This module uses the BCM2835 library through node-dht-sensor that requires access to /open/mem. Because of this, you will typically run node with admin privileges.

npm start

After that you can configure and run homebridge with the homebridge-http-temperature-humidity plugin.
