I don't think I was articulating the problem correctly since we were getting into legacy lighting and brightness levels so I've made a demo.
NOTE: This doesn't seem to happen for every keypad configuration. Definitely happens for equal height 3-button configuration.
I'm a little worried I'll get a "You're using it wrong" reply with the simultaneous tap, but
sometimes I tap both buttons on a keypad at the same time to turn both lights off (and that works if there's no double-tap programming)
it also happens if the taps are sequential, but very close together
Even simultaneous taps shouldn't trigger a double-tap on any single one of the buttons
Here is the programming for the demo, a simple announcement on double-tap:
And here is the recording:
double tap on the top button announces, as expected
double tap on the middle button does nothing, as expected
tapping top and middle button announces, UNEXPECTED
