It’s a shame that the charger is not upgradable it was bought in 2020 and The Bluetooth shouldn’t be that old not Support smart Networking
Or is there a way to manually install it or new firmware ??
It was a hardware change that made it compatible with VE.Smart Networking.
You can’t update the HW with a new FW.
The change to HW rev 2 was in mid 2020:
