Related to this, I still think think the original version of the Hue Tap switch was clever and I'm still surprised didn't have more clones and didn't entirely survive the internal revision wars/external protocol wars: the original didn't use a disposable "button" battery and instead used mechanical energy of pushing the button to power sending the Zigbee signal. It takes more force than a regular light switch to hit it with enough physical power, but it's also kind of satisfying in the way a mechanical keyboard button can be or a big chonky "snooze button" that you kind of want to smack with some force anyway. I've heard it said that sort of mechanical powered switch with Thread/Matter is much harder, except with these old existing ones in bridges with old Zigbee compatibility, and more's the pity. It still seems such a good idea to me, one less battery to waste/go bad at exactly the wrong time.
