I would like to do something like this, but it would mean moving the smart bits from my switches to my bulbs, which I'm just not really willing to do. Right now, if I take a hammer to my Home Assistant server, all my lights still turn on and off at the wall.

A good option might be to move to those new Inovelli Blue Zigbee switches and pair them directly with the bulbs. But I've already swapped all the switches in my house once...
