MQTT Client

This app was initially based on the MQTT Client for Homey made by Johan Kuster. With this app you will be able to send messages to a topic and receive messages from a topic. The app contains two cards. One for subscribing to a topic and receiving messages from that topic. With the other card you will be able to send a message to a topic. Wildcards in a topic are supported. The settings page contains: - The option to use the HiveMQ public broker - IP adres or DNS name of the broker wehre to connect top - Portnumber to connect to. - The option to use a secure session (TLS). No support for self signed certificates. - Possibility to bypass certificate check in case of self-signed certificates - Userid for the broker connection - Password to use for the broker connection PUBLIC API - send MQTT messages to topic - subscribe to topic API usage example Add homey:app:nl.scanno.mqtt to your app.json permissions. const Homey = require('homey'); const MQTTClient = new Homey.ApiApp('nl.scanno.mqtt'); class MyApp extends Homey.App { onInit() { MQTTClient .register() .on('install', () => this.register()) .on('uninstall', () => this.unregister()) .on('realtime', (topic, message) => this.onMessage(topic, message)); MQTTClient.getInstalled() .then(installed => { if (installed) { this.register(); } }) .catch(error => this.log(error)); } onMessage(topic, message) { this.log(topic + ": " + JSON.stringify(message, null, 2)); } register() { // Subscribe to all messages in the `homey` topic // messages will pass through the onMessage method via the realtime api MQTTClient.post( 'subscribe', { topic: 'homey/#' }, (error) => this.log(error || 'subscribed to topic: homey/#') ); // send a message try { MQTTClient.post('send', { qos: 0, retain: false, mqttTopic: 'homey/test', mqttMessage: { msg: 'Hello MQTT!' } }); } catch (error) { this.log(error); } } unregister(){ // ... } } YOU NEED ACCESS TO A MQTT BROKER TO BE ABLE TO USE THIS APP. Now it is possible to run a MQTT Broker in your Homey !!!. See my MQTT Broker app in the app store. It is still in beta at the moment, but fully functional.
