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 an end device, and gives you local control through Home Assistant. Because it runs without a neutral, it will not repeat signals for other Zigbee devices. 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.

Local control facts
Home Assistant: zha integration, Local Polling (home-assistant.io, checked Sep 10, 2026)
Zigbee2MQTT: supported device, listed as SONOFF ZBMINIL2 (Zigbee smart switch (no neutral)) (zigbee2mqtt.io, checked Sep 10, 2026)
Why it stands out
no neutral wire required - works in older homes without neutral at the switch box
fully local Zigbee control through ZHA or Zigbee2MQTT with no cloud account
very compact for a no-neutral relay
Reasons to hesitate
requires a Zigbee coordinator
Zigbee means no direct voice assistant control without bridging through HA
runs as a Zigbee end device, so it will not repeat for other devices or extend your mesh
Best for
older homes without neutral wires at the switch box
Zigbee Home Assistant users who want to keep the existing wall switch in place
Avoid if
you have no Zigbee coordinator
you want direct cloud or voice assistant control without Home Assistant
Privacy and local-control notes
The ZBMINI-L2 communicates over Zigbee and runs fully local via your coordinator and Home Assistant automations. There is no required cloud account, and switch telemetry stays on your internal network unless you intentionally expose it.
Home Assistant support: supported · integration path: zigbee2mqtt / ZHA.
Buying reality check
Price notes: Excellent budget value, especially in no-neutral homes where alternatives are limited. The small premium over basic relays is justified by easier retrofit installs and fewer electrical compromises.
Verified price reads: lowest seen $19.9, latest $19.9 on Sep 11, 2026.
Aqara vs Shelly vs Sonoff: which ecosystem for local-first smart homes?
Shelly for Wi-Fi relays with a real local API, Sonoff for the cheapest Zigbee, Aqara for polished Zigbee and Thread sensors. Where each wins, and the one I build on.
