@stelgenhof for mqtt discovery do I need to set MQTT_HOMEASSISTANT_DISCOVERY_ENABLED and MQTT_HOMEASSISTANT_DISCOVERY_PREFIX in config.h or is it enough to set it in the web gui? In other words do I need to do both? Using 0.5.1-dev (git cloned yesterday).
EDIT: never mind, I figured out why discovery hadn’t worked. The bulb thought it had already been discovered, but something went wrong. After turning discovery off and on again in the web gui sorted it! Great work.
