Well in the end neither somfy Tahoma, nor Nuki 3.0

Well in the end neither somfy Tahoma, nor Nuki  3.0 with integrated Wifi nor Netatmo do connect to the iOT Network of the RBRE960. All say "wrong password", though computers and mobiles do connect with the same password. Even my Tesla does NOT connect to the 5G Network giving me the same "wrong password" nonsense message. If you are going to tell me I had to exchange all these devices, because Netgear is not doing anything wrong but all these vendors do. I will return my Netgear Router + 4 Satellites and buy a devices the others can use. Its easy as that. Its against all my experience in the IT world in these last 50 years that in a case were one vendor does not operate with 4 others the one is right and the 4 others are wrong.

How do you have the IoT broadcast configured?

How do you have the IoT security set for on the RBR? 

If you disable WPA on the IoT broadcast temporarily, do your devices connect then? Re-enable WPA2 after testing.

have you tried disabling wpa3 and trying wpa2? 

I've had a few IOT devices that struggled with wpa3
