Seems like using the Lutron Aurora dimmer switches that just attach to any regular wall switch or dimmer would be a much better option. No rewire needed. It pairs to the hue hub and it prevents anyone from turning off the physical switch. I have one for every wall switch in my house. Best thing they ever made for smart home tech.
The Philips Hue wall switch module makes it possible to control smart lights with a conventional switch without cutting the power supply to the lamps. Until now, these modules were wireless and relied on a battery, but this is apparently about to change.
