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...).
The Sonoff ZBMINIL2 needs no neutral wire, so it works on a plain 2-core lamp cord.
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.
Ive also made a bigger version of this switch (easier cable management) here
