Support push buttons
A push button (stateless programmable switch) should listen to group addresses and translate them to single, double and long press event.
Would this be a “HomeKit button” that you can use to trigger a specific KNX scene?
No, the other way round. A HomeKit button whose button presses (single, double, long press) are triggered by scenes. Those button presses can be used to trigger other actions, ex. turning on non-KNX HomeKit accessories.
With the existing options in the application today, is it possible to trigger KNX scenes?
Imagine a GA that turns all lights ON/OFF. I would like to have a button that always sends an OFF to this GA.
Using the normal switch accessory doesn't work since it remembers state. I tried to initialise/read from a GA that is always ON. The switch accessory is smarter though and turns itself off anyway. In effect the switch needs to be pressed twice until it sends OFF again. Better than nothing but can't be used in scenes properly.
Not sure this feature will do that. A stateless programmable switch that always sends ON/OFF would be really nice to have though. 😄
Is there any update on this? Implementing it like Thinka has done it would be great: https://www.thinka.eu/faq/how-do-i-configure-my-push-button
@willgf So you want to have a button which is triggered by a group address? The button is then used to trigger actions in HomeKit?
Yes exactly. So the KNX pushbutton sends a scene number onto a group address, the bridge listens for this scene no on that GA. This means that can use your KNX "taster"/pushbuttons as triggers within Homekit. Ideally, with a single/long/double press. I really like the way Thinka implemented it (see their FAQ).
Basically this would allow all scenes to "live" in HomeKit (which would also improve the user experience, as scenes can easily be changed within Homekit without ETS) with the KNX button merely acting as a trigger.
How many buttons do you want to configure per push button? Are 8 buttons reasonable?
