I have one of the SONOFF Zigbee 3.0 USB Dongle. It is attached to my home server and provides me with Zigbee connectivity for smart home integrations. The problem is that occasionally I have two sensors that drop off the network, after which I need to pair them again to get them working again. I’m hoping that flashing the latest firmware on to the Zigbee dongle may help. I wanted to use an ARM-based Macbook to flash the new firmware.
