SONOFF ZBMINI-L2

Quick verdict

The ZBMINI-L2's big trick is no neutral wire required — a lifesaver in older homes. It tucks behind your existing switch, joins the Zigbee mesh as a router, and gives you local control through Home Assistant. Compact enough to fit in most switch boxes, though tight ones can be a challenge.

Standout: No neutral wire required — the key upgrade over the original ZBMINI for older wiring.
