It has 111 installs sharing analytics, works locally and was last updated October 27, 2026. 1-Wire SysBus is a Home Assistant integration that reads 1-Wire sensors through the system bus, working locally. It is a spin-off of the original 1-Wire integration, which was removed from Home Assistant Core in version 2022.6. It adds sensor entities for devices found on the 1-Wire bus when the platform starts. Support is limited to temperature readings from DS18B20 devices (family 28), because it relies on the Raspberry Pi kernel modules for GPIO 1-Wire. The bus can be wired directly to Raspberry Pi pins or through an adapter such as the DS9490R. Connections through owserver are not supported, but the core 1-Wire integration can run alongside it for that purpose. Setup is done in the UI, where a mount directory is entered.
