Smart light switch default behaviour (lemmy.ca)

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?

The Enbrighten Zigbee switches I installed in some rooms work exactly as you note, if the zigbee network collapses for some reason, they still control the outlet or light they are hard wired to like any other dumb switch. I think for hardwired switches this is the normal behavior. For anything like Hue or Ikea Tradfri switches that are battery powered I think it highly depends on what they are connected to.

Shelly dimmers behave like that. I might have changed a setting here and there in stock firmware but they also integrated into home assistant with an import script someone posted on the HA forums, no need for some app. The ones I have are WiFi though.

Wemo switches work like normal switches when the network is out. They even run any schedules they knew about before the outage.
