Nowadays everything becomes connected to the Internet and gives us a glimpse of many new possibilities. Home automation is part of it and offers many advantages for their users. This repository is dedicated to Home Assistant, an open source project with an amazing community, ESP8266 and ESP32 modules, the MQTT protocol and much more [...].
Home Assistant is a home automation platform running on Python 3. The goal of Home Assistant is to be able to track and control all devices at home and offer a platform for automating control [Home-Assistant].
MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium [mqtt.org].
Most of the examples below are using the MQTT protocol and so require to integrate MQTT into Home Assistant by defining a MQTT broker. More information can be found at the MQTT component's page.
configuration.yaml :
mqtt:
broker: 127.0.0.1
port: 1883
username: '[Redacted]'
password: '[Redacted]'
discovery: true # optional
discovery_prefix: homeassistant # optionalconfiguration.yaml :
mqtt:
broker: core-mosquitto
username: '[Redacted]'
password: '[Redacted]'
discovery: true # optional
discovery_prefix: homeassistant # optionalMore options to connect the broker are available and described here.
Lights, sensors, switches and more can be built on top of MQTT. This section contains a few examples based on MQTT and on a NodeMCU board (ESP8266/ESP32).
