Thanks everyone! Sorry, I didn't do a great job explaining the Why.
* Most guests don't understand that lights need to be turned off using a double click. My kids struggle with it too. (Yes, I have motion sensors, so lights don't really need to be switched off very often, but 1. they're not in every room and 2. I disable them in Night mode.) From UX PoV, people IMHO subconsciously expect a single-tap operation: tap once: lights are on, tap again, lights are off.
* I have the basic Touch Tree buttons, i.e., the plastic ones. I'm not sure what's wrong exactly, but maybe 30% of the cases when I try to double-tap, only the second tap gets registered, i.e., instead of turning off the light, it just cycles the mood.
A simple solution to my, perhaps extravagant requirement is to simply only have 2 moods: On and Off. But then I like moods! Well, I only really have 2: Bright and Dim, but still!
So what I was hoping for is what I crudely tried to describe above. Perhaps a different way to look at it (i.e., no long clicks involved):
* If off, a tap turns the light on.
* If on, a tap turns the light off. *Except* for when the tap comes within X seconds (say 3) from the last one, it cycles the mood instead.
I guess I could Pico-C this, but I'd need a block for every Touch and I'm guessing it's not great to have so much Pico-C.
Again: My Loxone setup works great, this is my first smart home and I'm having a ton of fun with it. This single-tap thing is almost a vanity, I was just wondering if others might have thought about something like this, too. There's a good chance I'm fixing the wrong problem, too!
Thanks!
