Talkat Open Source Summit Europe + Embedded Linux Conference Europe 2019 · on Wednesday, 2019-10-30· at 15:15· Forum 6·
summary
Explains why MQTT becomes dominant for home automation and shows concrete recipes: use Mosquitto broker on a Raspberry Pi, implement MQTT discovery topics and JSON/plain payloads to register sensors with Home Assistant discovery, or follow the Homie convention to expose nodes/properties. Covers QoS 0/1/2 and retained messages, gives examples (ESP8266 + DHT22 sending temperature, binary on/off sensors, MQTT-controlled RGB LED strips integrated with Alexa) and demonstrates OpenHAB and Domoticz integration and the exact topic/payload formats used.
