Arduino Home Assistant

ArduinoHA allows to integrate an Arduino/ESP based device with Home Assistant using MQTT. The library is designed to use as little resources (RAM/flash) as possible. Initially it was optimized to work on Arduino Uno with Ethernet Shield, but I successfully use it on ESP8266/ESP8255 boards in my projects.

Examples

• Binary Sensor
• LED switch
• MQTT with credentials
• Multi-state button
• RFID tag reader
• Sensor (temperature, humidity, etc.)
• NodeMCU Wi-Fi

Tested boards

• Arduino Uno
• Arduino Mega
• Controllino Maxi (standard/pure/automation/power)
• Controllino Mega (standard/pure)
• NodeMCU
• ESP-01
• Generic ESP8266/ESP8255

Tested Arduino Shields

• Arduino Ethernet Shield (WizNet W5100)

Supported HA types

• Binary sensors
• Device triggers
• Switches
• Sensors
• Tag scanner

Unsupported features

The library doesn't support all features of the MQTT integration. If you need support for a new feature please open a new issue in the repository.
