MQTT 101: Integrate your DIY Devices into Home Assistant

In this video, I'm going to show you how to use MQTT to integrate your custom DIY devices into Home Assistant.

After covering the basics of MQTT and how it works, I'll show some examples of using MQTT in Home Assistant, how it can be added to your custom device and how to integrate that device into Home Assisant via automations, sensors and switches. I'll show all this with a real world example of a DIY device I integrated into Home Assistant using MQTT.
