SONOFF ZBMINIL2 Zigbee 3.0 Smart Switch – No Neutral Wire Required

No neutral wire in your flush-mounted box? No problem at all.

In many Dutch homes, especially in older buildings, there is no neutral wire (N) present behind the wall switch. Most smart in-wall switches then won't work. The SONOFF ZBMINIL2 Zigbee MINI Extreme is specially designed for this situation: it works with just two wires (L in and L out) and makes any ordinary switch smart – without demolition, without extra wiring.

⚡ Ultra compact – fits in almost any flush-mounted box

With dimensions of only 39.5 × 32 × 18.4mm, the ZBMINIL2 is 40% smaller than its predecessor ZBMINIL. A minimum depth of 47mm is recommended for comfortable installation. The relay switches up to 6A / 1500W – ideal for lighting.

⚠️ No neutral wire – but a minimum load of 3W

Since the ZBMINIL2 does not have a neutral wire, it draws a small amount of current through the load. This requires a minimum load of 3W:

• Minimum 3W LED lighting required
• LED maximum: 150W @ 100V / 300W @ 240V
• Not suitable for inductive loads such as fans or motors
• For flickering lights: a bypass module can help

⚠️ ZBMINIL2 is a Zigbee End-Device – NOT a router

The ZBMINIL2 is a Zigbee End-Device and does not function as a Zigbee router. It therefore does not amplify the Zigbee network. In large homes or with many Zigbee devices, it is advisable to include Zigbee routers (such as the ZBMINIR2) in the network.

🔀 Supports multiple switch types

• Toggle switch (factory settings)
• Push button (momentary)
• Two-way switch (SPDT – two-way control, e.g., staircase lighting)

Easily switch between switch types by pressing the button 3 times briefly.

🛠️ Smart functions

• Timer Schedule: switch on/off at fixed times
• Countdown timer: automatic shutdown after adjustable time
• Loop timer: repeating on/off cycles
• Power-on State: adjustable behavior after power interruption
• Smart scenes: link with other Zigbee devices
• Local Zigbee scenes: also works without an internet connection

⚠️ Please note: The ZBMINIL2 does not have a Detach Relay Mode. When using smart lamps that need to be continuously powered, the ZBMINIR2 is a better choice.

⚠️ Safety Warning

The ZBMINIL2 operates on 230V AC current and must be installed by a certified electrician. Ensure that a 6A MCB or RCD (RCBO) is present before the ZBMINIL2. Never connect the S1/S2 terminals to the neutral or earth wire.
