Setting up MQTT with Auto-Discovery on Home Assistant (settings)

After you’ve installed things for MQTT in Home Assistant, it’s time to make some settings. 1. Enable debug logs. I don’t actually have much insight into what this does, but whatever. It sounds good. I did it. It didn’t hurt. In the configuration.yaml file (see previous post for information on how to edit files), add: logger: default: warning logs: homeassistant.components.mqtt: debug … and then reload the settings by restarting. Configuration -> Server Controls -> Check Configuration.

Setting up MQTT with Auto-Discovery on Home Assistant (software setup)
