# Random Sensors Small library that generates random messages on an MQTT brocker. ## Messages topics and payload Sensors publish on 2 topics : - `"presence"` with payload `[id]` where "[id]" is the id of the sensor. - `"value/[id]"` with "[id]" the id of the sensor and a payload with format : ```JSON { "value": "[value]", "type": "[type]" } ``` where "[value]" is the string value of the sensor and "[type]" the string representation of the type of value within: - 'POSITIVE_NUMBER', - 'PERCENT', - 'ON_OFF', - 'OPEN_CLOSE'. ## run it Run a default example with: ``` npm install node test-random-sensors.js ``` ### launch with Docker To launch the generator, place yourself in the project directory and launch : ``` docker-compose up -d ``` And it's done. You can now connect your MQTT client to `127.0.0.1:1883` via the MQTT port, and to `127.0.0.1:8080` via the WebSocket port. # WebApp A Web APP that use React and redux to get the message from the MQTT brocker. ## run it ``` npm install npm start ```
