Guides
Bring-up, deployment, and common issues for current products.
Flash firmware on ZBM-MG21 / MG24
Use the official Inswift Silabs Flasher to write or upgrade NCP firmware on MG21 / MG24 coordinators.
Placement and interference: why a USB extension matters
The coordinator is a 2.4 GHz radio. Putting it in the right place often helps more than buying a higher-end chip.
Add a coordinator to Home Assistant with ZHA
From plugging in USB to joining devices, using Home Assistant's built-in ZHA integration — no separate Zigbee2MQTT process.
Zigbee2MQTT with an Inswift coordinator
TI radios use adapter: zstack; Silabs radios use EZSP / ember. For users who want fuller device exposure.
Tools
Firmware, flashers, and docs, maintained with the products.
ETH dongle online upgrade
