mqtt2atlonamatrix

Bridge from MQTT to Atlona HDMI matrix switches. Attempts to follow mqtt-smarthome pattern.

mqtt2atlonamatrix is a Node.js application that links Atlona HDMI matrix switches to an MQTT broker. It is designed to be used to integrate these devices into a home automation system à la mqtt-smarthome.

Getting Started

mqtt2atlonamatrix is distributed through NPM:

npm install -g mqtt2atlonamatrix
 
# or, if you prefer: 
yarn global add mqtt2atlonamatrix

Running it is likewise easy:

mqtt2atlonamatrix                      # if your MQTT broker is running on localhost 
mqtt2atlonamatrix -b mqtt://<hostname> # if your broker is running elsewhere 
mqtt2atlonamatrix --help               # to see the full usage documentation
