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

`atlonamatrix/status/hardwareInfo`	JSON-encoded hardware info; format: `{ "type": "", "version": "" }`
`atlonamatrix/status/outputStatus`	The current status of each output as a lis

Topics Subscribed

For performance reasons, no argument checking is done: commands are passed diectly to the switch.

`atlonamatrix/get/hardwareInfo`	Force a refresh of the hardware info
`atlonamatrix/get/outputStatus`	Force a refresh of the current output status
`atlonamatrix/set/isOn`	Set the system to Off.
