Sonoff Dongle-E Plus V2 - FW update for ZHA?

Configuration Zigbee
1

Hi,

I have a Sonoff Zigbee 3.0 USB Dongle-E Plus V2 dongle on a USB ext cable plugged, into a USB 2.0 port of a Rasp Pi 5.
I have ZHA currently seeing the dongle OK, although am having ‘unavailable’ issues with 2 battery powered Sonoff Zigbee devices.

Current Firmware is 6.10.3.0 Build 297

I see 7.4.4 is available - are there any advantages to me by upgrading ?

I have a related thread running:
