Siedle HTS811

Hello everyone, I own a Siedle HTS811 system. A few days ago, I purchased the Nuki Opener and unfortunately only just realised that Nuki no longer supports Siedle systems. I was shocked. Siedle is one of the largest manufacturers and Nuki is ending the collaboration, which I find very sad. My problem is that I don’t have any instructions on how to connect my HTS811 to the Opener. Does anyone have the same system and could please help me? Perhaps a photo of the wiring would be enough. I would be very grateful.
