Integrating Hue Tap Dial with Elixir and MQTT for Smart Home Automation

This article describes the process of integrating Hue Tap Dial switches into a smart home setup using Elixir and MQTT, moving away from relying on Home Assistant. The author shares insights on using Zigbee2MQTT as a bridge for Zigbee devices and the benefits of low-latency communication for controlling smart lighting. The post details the implementation of various functionalities such as dimming lights, toggling them on and off, and handling button presses, as well as the challenges faced with latency in Zigbee networks. Additionally, it covers how to create a generalized controller for managing multiple tap dials, highlighting the flexibility and customization possible with direct MQTT communication.
