I replaced my old HTA 611-11 with a Siedle IQ HTA. Since it is not listed in the Nuki App, I tried the almost identical HTA 811. Unfortunately this was not successful. Is there a possibility to operate the IQ with the Opener? I miss the Ring to Open function a bit.
Hello Henning, did you manage to get your setup working? I have the same setup and will try it some time soon 
Best regards.
