Buy this only if your back box genuinely has no neutral wire — if it does, get the ZBMINIR2 sibling instead: similar price, 10A instead of 6A, and it works as a Zigbee router rather than an end device, which does more for mesh coverage. Like any no-neutral relay, it bleeds a trickle of current through the load to stay powered, so some dimmable LED drivers flicker or won't fully switch off; SONOFF rates it down to 3W with no bypass capacitor required, but cheap dimmable bulbs are still worth testing first. At roughly £14, it's the going rate for a no-neutral Zigbee relay.
What can Home Assistant control on the SONOFF ZBMINIL2?
| Control | Type | What it does |
|---|---|---|
| Switch | Switch | Primary relay control (on/off/toggle) exposed as a standard HA switch entity. |
| Power-on behavior | Select | Enum (off/on/toggle/previous) controlling relay state after a power cut. |
| Detach relay mode | Switch | Decouples the relay from the wired external switch input so the physical rocker no longer directly cuts relay power; the switch becomes a separate action source instead. |
| External trigger mode | Select | Configures how the wired external switch signal is interpreted (edge, pulse, following-off, following-on) to match rocker vs momentary switches. |
| Switch action | Event | When state_action is enabled, publishes physical switch presses as action events usable as a stateless automation trigger. |
Set external_trigger_mode (edge/pulse/following-on/following-off) to match your existing rocker or momentary switch wiring, and flip on detach_relay_mode if you want the wall switch to stop physically gating the relay — instead it fires a stateless action event (with state_action enabled) that HA can use as a trigger while the Zigbee relay stays live and independently controllable. Several ZBMINIL2 units are reported dropping off the mesh after ~30-40 seconds or ~30 minutes while still echoing correct state locally, requiring a manual re-pair (flip the physical switch 5x); check firmware is at least 1.3.0, since earlier releases had a documented power-on-behavior bug.

Frequently asked questions
- Does the SONOFF ZBMINIL2 work with Home Assistant locally?
- Yes. The SONOFF ZBMINIL2 is controlled locally in Home Assistant through Zigbee2MQTT or ZHA, so it keeps working if your internet connection or the SONOFF cloud goes down. Control and state updates stay on your own network.
- Which protocol does the SONOFF ZBMINIL2 use, and do I need a hub?
- The SONOFF ZBMINIL2 uses Zigbee. To pair it with Home Assistant you need a Zigbee coordinator (for example a SkyConnect/ZBT-1 or Sonoff dongle) attached to your Home Assistant host. SONOFF's own hub is not required when you integrate through Zigbee2MQTT or ZHA.
- How much does the SONOFF ZBMINIL2 cost in the UK?
- The lowest price we have listed for the SONOFF ZBMINIL2 is £13.63 at Amazon UK. Prices were last checked in September 2026 and change often, so confirm on the retailer's page before buying.
