ActiveSONOFF ZBMINI L2 Zigbee Smart Switch (No Neutral)
SONOFF ZBMINI L2 — converts any wall switch to Zigbee smart, no neutral wire needed.

The existing switch becomes a physical trigger while the ZBMINI controls the load. Solves the retrofit problem for homes without neutral wires at the switch box.
