Make any lamp with a flat cord smart, and keep a real switch on the cord.
Switch the lamp with the rocker or over Zigbee (Home Assistant, Zigbee2MQTT, Sonoff gateway ...).
The Sonoff ZBMINIL2 needs no neutral wire, so it works on a plain 2-core lamp cord.
Ive also made a 15% smaller switch just like this one here.
Everything is click-in: the lid, the Sonoff, the rocker, the WAGO and the cord locks all snap into place. No screws needed.
Good strain relief: the cord is locked in an S-bend and does not pull out.
Sonoff button and LED are accessible through holes in the back.
