The SONOFF ZBMINIL2 is a tiny Zigbee 3.0 relay (no neutral required) with S1/S2 two-way switch support and OTA capability; it’s notable for its 39.5×32×18.4 mm compact size and native integration with Zigbee2MQTT/ZHA/Home Assistant. Strong choice for retrofit smart switches where space and local Zigbee control matter, but expect it to behave as an End Device (not a router) and to need a minimum load (~3W) and careful in-box cable routing.
Buy if you need a tiny, no-neutral Zigbee relay for retrofit two-way switches; avoid if you need a mesh router or use very low-wattage LED loads.
