I've chosen MQTT because of it's robustness and lightweightness allowing for easy deployment on my favourite controllers: ESP8266. The broker should be listening for websockets on port 9001. The MQTT port remains the default of 1883. After testing that, we're gonna want to start it automatically The MQTT Dashboard utilizes the HiveMQ MQTT broker. You can use any MQTT client or library to publish to the broker. Testing and usage is for free but please do not use it for sensitive information because everybody is allowed to subscribe to every topic, including wildcard
