I am not sure I understand exactly how you mean, so please correct me if I misinterpret your suggested solution, but I would like to refer to my intial post (see the fourth requirement). If you use the SONOFF ZBMINI-L () and bypass the switch so it’s always on, it would essentially act as a sensor for whenever somebody interacts with the switch. I guess what I am asking is, does anyone know of a product or solution that can accomplish this in a neat way? I suspect one way to do this would be to wire the switches in a way that the bulb is always powered, but this would require re-wiring should I want to re-configure one or several lights. I have purchased smart switches from both Sonoff and Sunricher but they don’t seem to offer the decoupled option. I suspect that the Ubisys S1 might allow disabling the relay but since they are 99 € I would like to check for cheaper options first. Also, I do not want to rely on a battery powered device. “decoupled mode” but I really do not want to use Wi-Fi devices unless I have no other choice.

Shelly, that offer the option to disable the relay i.e. Not having to rely on bypassing the switch with wiring (edit: added this for clarity).Use the grid/mains to power said device.

Use the physical light switch to turn on and off smart bulbs (without toggling the power to the bulb).

I have been searching all corners of the web for a product or solution that can allow me to do the following in my smart home setup Tl dr - does anyone know of a smart Zigbee switch that has support for decoupled mode?
