In this video, I walk through the full setup of Thread OBR (Open Thread Border Router) running directly on the SMLight SLZB‑MR3U — no USB passthrough, no extra hardware, and no Home Assistant add‑on required.
This update lets the SMLight SLZB‑MR3U run Zigbee AND Thread in one device, making your smart home cleaner, faster, and easier to manage. I show the firmware update, configuration steps, Home Assistant integration, Matter pairing, and how to get your Thread devices connected through the new onboard OBR.
If you’re using the SMLight SLZB‑MR3U or planning to upgrade your smart home network, this guide will walk you through everything step‑by‑step.
