The Push Button Smart 86 is a good option where the wall switches warrant an upgrade from the simple “Press” buttons installed initially. They’re highly configurable, with 6 buttons configurable as a simple set of 6 functions or up to 12 functions (arranged as 3 sets of 4 functions) via multiple ‘levels’ (as they’re called in the documentation but really they’re ‘tabs’ or ‘pages’).
If there’s one downside to these switches, it’s that they have a lot of configuration options and the programming isn’t that intuitive (and the documentation isn’t that great – at least not in English).
These notes describe how they are configured and some of the lessons from trial-and-error configuration. Bold text indicates changes from the defaults. Verified for v2.5 of the KNX database.
