It has 40.4k installs sharing analytics and was last updated October 26, 2026. OpenThread Border Router is an app that turns a Home Assistant installation into a Thread border router. The border router can be used to commission Matter devices that connect through Thread. Home Assistant Core detects the app and creates an Open Thread Border Router integration, which is configured automatically on Core 2023.3 and newer. It needs an 802.15.4 radio flashed with OpenThread RCP firmware, such as Home Assistant Yellow, SkyConnect or Connect ZBT-1, or Connect ZBT-2. Setup consists of choosing the radio device in the app configuration and starting the app. An optional web interface for debugging can be enabled by exposing its ports on the host, and the app runs on Home Assistant OS with hardware access and host networking.
