I have both an Aeotec Z-Stick 5+ and an Aeotec Z-Stick 7 (firmware 7.26.1) and I live in Europe.
I’ve set up my Home Assistant OS on a Raspberry Pi 4 and started with the Z-Stick 7 as it was newer (so better, right?) but that was before I read here Z-Wave adapters - Home Assistant that:
Aeotec Z-Stick 7 USB stick (ZWA010) (the EU version is not recommended due to RF performance issues)
Would I be better off with the Z-Stick 5+?
If so, what is the best way to migrate my nodes from the Z-Stick 7 to the Z-Stick 5+?
The Z-Stick 5+ with the most recent firmware is much better than the Z-Stick 7, but it is severely outdated and the ZWA-2 with its unique antenna and Z-Wave 800 LR support is in a wholly different league.
