john30/ebusdWhat is ebusd?
ebusd handles communication between home heating systems using the eBUS protocol on a 2-wire energy bus. The daemon supports multiple connection methods including USB serial, TCP, and UDP, auto-discovers devices via mDNS, integrates with Home Assistant through MQTT Discovery, publishes data to Azure IoT Hub, acts as a KNX device for building bridges, provides HTTP JSON API access, includes basic HTML interface, and supports user authentication via ACL files.
