Sonoffs Zigbee 3.0 USB Dongle Plus Firmware Upgrade when in use


I’m currently using the Sonoffs Zigbee 3.0 USB Dongle Plus for my ZHA configuration. I already have 45 devices connected. Is it possible to flash the stick without the need to connect all devices again manually?


I don’t know the answer.
I’ve tried to flash my DongleP with GitHub - mercenaruss/zigstar_addons: Home Assistant add-ons for Flashing ZigStar Devices yesterday.

Since then, ZHA doesn’t work anymore :frowning:

I haven’t figured out yet what went wrong – just a friendly precaution…

Yes, an update should not affect your zigbee network. Follow the steps here:

Shut down HA before doing the upgrade.

I believe this is not the correct firmware for Sonoff. Try flashing it again following the steps in this video:
