"This also rules out smart light switches, as these often need to connect to some kind of cloud, and if that cloud goes down, you could struggle to turn your lights on." Hu? No it doesn't. It's a switch, you press it and the light goes on and off, it needs no cloud connection at all. You can automate it if you like, but you don't have to. And his choice was instead to use a proprietary "Shelly" device that uses WiFi instead? With its own "Shelly cloud"? I'm sorry, but that was a bad decision. Get a standard Z-Wave or Zigbee switch, it functions as a real switch, because it's a switch. Then get a Hubitat, which runs entirely locally, and needs no internet unless you want to connect it to Amazon Assistant or Alexa (and you don't have to). This is future proof, and outage proof - the light switch function as dumb switches, the Hubitat runs entirely locally, with zero internet (not even local internet). And Z-wave or Zigbee are standards and you can interoperate with tons of other devices, so no worry about some manufacturer going out of business.
