MQTT to GPIO node library

Quick and simple library to get a node topic setting state on a Raspberry Pi GPIO pin.

Quick start:

• clone this repo on to a RaspberryPi:

  git clone https://github.com/zymotik/mqtt-gpio.git

• switch to the mqtt-gpio folder

• install node libraries:

  npm install

• edit settings:

  • Copy: copy settings.sample.json settings.json
  • Edit: nano settings.json

• run library

  sudo npm run start

In my use case, I'm using Home Assistant climate app to turn on a heating zone relay.

Look at my other node packages for code to publish OneWire events to MQTT topics for Home Assistant.

Setting up as a service on a RaspberryPi

Install forever and forever-service on the RaspberryPi

sudo npm install forever -g

sudo npm install forever-service -g

Then run in the source directory (where this readme.md file is):

sudo npm run service-install

And to remove:

sudo npm run service-remove

To view service logs use the command:

sudo npm run view-log

Developer notes

npm install will fail on anything but a RaspberryPi. To install and run tests, use npm run install-none-pi before npm run test.
