@Rose_Languste As I’ve mentioned in your other post Why is TCS not on the Compatibility-List for the Opener!? - #3 by Rose_Languste
I’m sorry to inform you but as of 01.06.2022 upon a previous request by TCS TürControlSysteme AG
we have discontinued our official support for TCS intercoms for the Nuki Opener. Existing Nuki Opener setups can still be used.
