I’m looking to get some smart light switches/dimmers (zigbee or matter if that’s relevant), and one of the requirements for me is that if the switches aren’t connected to the network, they would behave like regular dumb switches/dimmers. No one ever advertises anything except the “ideal” behaviour when it’s connected with a hub and their proprietary app and everything, so I haven’t been able to find any information on this.

So my question: is this the default behaviour for most switches? Are there any that don’t do this? What should I look out for given this requirement?
