I am thankful I’ve never seen this (or at least, have not seen it yet).
I have however seen plenty of “app” style webpages over the years, but for a lot of them it makes sense, good examples would be Gmail and web based communication programs (discord in the browser as an example). They have to load a bunch of JavaScript and other resources to function.
I’ve put a few smart lights/switches/sensors/power points in at home. Definitely helps mum as we can have wireless switches for the lights, and motion sensors to turn the hallway lights on automatically as well.
For ALL of them, I make sure there is a manual control that will work as a backup regardless. Even if a smart light is “off” due to the motion sensor not detecting movement, all you need to do is turn the old regular light switch off then back on and the light will default to being back on.
