I've read about various in-wall switches and some other devices (like battery-powered portable or on-wall scene controllers) supporting double pushes, and in fact some of them mention absurd numbers of pushes (absurd to keep track of in my head! But it's fine, I don't have to use it, if it really doesn't work for me to use that feature).
Is that common or rare? How do I tell if my device supports it? And if my device supports it, how do I access it in scripting?
Also, speaking of in-wall controllers, is there an AC-powered in-wall scene controller available? All the ones I can find are battery-powered, and I hate building battery-powered things into my house with a fiery passion (and I hate running around replacing batteries, and I hate the ever-growing number of kinds of batteries you need to stock, and so forth; possibly I am becoming a grumpy old man?). I guess any in-wall switch can be used as an in-wall button, you can access that in programming, but it'd be more powerful if you could access multi-pushes too.
