Sonoff Zigbee 3.0 Model E - Repeater function

i got a second Sonoff Zigbee Dongle 3.0 Model E and i would like to use it as a repeater, so that my Zigbee network will be better.

  1. Is there a “How-To” to flash that stick and use it as a repeater in my Zigbee Network
  2. How can i add this to my ZHA instance in Home Assistant?
  3. When the stick is ready to use, can i put it in any USB Plug? Just needs energy?

This should cover the tutorial

Yes, just leave it plugged to any usb charger
