Hey everyone, I’m currently working on integrating my ComfoAir ventilation system with both OpenHAB (OH) and KNX. While controlling the fan speed via OH works perfectly, I’m facing some challenges with the KNX integration. Let me share my journey and see if anyone can offer some insights or solutions.
So, here’s the setup: The fan speed is controlled by a Setpoint item in OH, which allows me to increase or decrease the fan level using the + or - buttons. This works like a charm. However, in KNX, I only have a single item called Lueftung_manuell_steuern, which sends either ON or OFF signals. The goal is to map these ON/OFF signals to the corresponding + and - actions of the Setpoint item in OH.
I’ve tried a few approaches, but nothing seems to stick. For instance, I considered creating a rule that triggers when the KNX item changes state and then adjusts the Setpoint item accordingly. But I’m not entirely sure how to implement this without causing unintended behavior. Maybe I need to use some transformation or a custom mapping in the bindings configuration?
Has anyone successfully integrated KNX controls with OpenHAB Setpoint items before? Any tips or best practices would be greatly appreciated. I’m also open to exploring alternative methods, such as using a different binding or adjusting the KNX configuration itself.
In the meantime, I’ll keep experimenting and documenting my findings. It’s a bit of a puzzle, but I’m determined to crack it!
Thanks in advance for your help and insights!
