Set of 2 smart ZigBee 3.0 switch without neutral wire 1-channel eWeLink
Turn your home into a smart home without complicated construction work and additional wiring! Set of 2 smart ZigBee 3.0 switches without neutral wire (model Sonoff ZBMINIL2 Extreme) represents a revolutionary solution for anyone who wants to easily upgrade existing switches to smart versions. Since the switch does not require a neutral wire (zero) for its operation, installation is extremely simple and suitable for every Slovenian household.
This ultra-compact set of two switches gives you complete control over your lighting and other electrical devices. Compatible with leading smart home systems, it works via the eWeLink app, and also supports Tuya, Amazon Alexa and Google Assistant. Control your lights with your voice, create schedules or monitor your home remotely – anywhere, anytime.

Why choose Sonoff ZBMINIL2 Extreme smart switch?
The biggest problem when upgrading classic switches to smart ones is often the absence of a neutral wire in wall boxes. With the Sonoff ZBMINIL2 switch, this worry is a thing of the past. This innovative ZigBee switch works exclusively on the phase wire, which means you can simply replace your existing switch without pulling new cables. Due to its extremely small dimensions (only 39.5 × 32 × 18.4 mm), it fits easily even in the smallest mounting boxes of EU/86/120 standards.
Despite its small size, the switch offers exceptional performance. It supports bidirectional control (ideal for stairwell lights), operates with low power consumption thanks to the advanced EFR32MG22 core, and ensures safe operation with a housing made of flame-retardant PC plastic with a V-0 resistance class.

Easy to install and use
Installing the Sonoff ZBMINIL2 Extreme switch is quick and safe. Simply install the switch behind your existing wall switch (it can be a classic rocker or a wall switch with buttons). After connecting the wires, pair the device via Bluetooth technology in the eWeLink application, which connects it to your ZigBee gateway (Hub). From that moment on, you have complete control of your home at your fingertips - regardless of whether you are in the office, on the go or on vacation.
Since the device supports local connection via the ZigBee 3.0 protocol, your set smart scenarios and schedules will work smoothly even if your home internet connection temporarily drops. This ensures exceptional reliability of your smart home operation.

Frequently Asked Questions (FAQ)
1. Does this switch really not need a neutral wire (zero)?
Yes, the Sonoff ZBMINIL2 Extreme switch is specifically designed to operate without a neutral wire. It only requires a phase wire to operate, which greatly simplifies installation in most older and standard electrical installations in Slovenia.
2. What gateway (Hub) do I need for this switch to work?
Since the switch uses the energy-saving and stable ZigBee 3.0 protocol, it requires a compatible ZigBee 3.0 gateway (e.g. Sonoff Zigbee Bridge, Tuya Zigbee Hub or other compatible gateways) to operate.
3. Can I also control low-power energy-saving LED bulbs with this switch?
Of course! The ZBMINIL2 switch enables stable and reliable lighting control, even when the power of the consumer (lamp) is extremely low - down to just 3 W, without the need to install additional anti-flicker bypass capacitors.

Instructions for using the product:
1️⃣ Turn off the power supply before installation. 2️⃣ Remove the existing switch and connect the smart ZigBee switch. 3️⃣ Connect the phase cable (L) to the appropriate connector, as the neutral cable (N) is not required. 4️⃣ Turn on the power and switch the switch to test operation. 5️⃣ Pair the switch with the ZigBee hub (eWeLink or Tuya) in the app. 6️⃣ Add the switch to the eWeLink app and set schedules, scenes or voice control.

Useful tips:
💡 Automate turning lights on and off according to a schedule. 💡 Connect the switch to other smart devices for advanced automation. 💡 Use voice control to easily turn on lights. 💡 Check ZigBee hub compatibility, as the switch requires a central unit. 💡 Combine the switch with a motion sensor to automatically turn on lights.

Warnings:
⚠️ Indoor use only - the switch is not waterproof.⚠️ Do not connect without turning off the electrical wiring - risk of electric shock.⚠️ ZigBee hub is required for operation - check compatibility before purchase.⚠️ Only suitable for lighting circuits, not for high-voltage devices.⚠️ Do not use with incompatible smart platforms - check eWeLink support.

Same summary

The set of two ZigBee 3.0 smart switches without a neutral wire is particularly suitable for upgrading existing switches where a neutral wire is not available in the box. Such a product is a good choice for users who want to expand the functionality of their smart home without major installation interventions or additional hub devices (if they are already in the Zigbee ecosystem). It is important to check beforehand whether there is enough space in the box for installation at the selected location and compatibility with your current Zigbee hub or ecosystem.

Due to its single-channel design, the product may not be the best choice for those who want to control multiple balls or complex schemes with a single module.

Answers to frequently asked questions

Can I use these switches where there is no neutral wire?

Yes, this module is specifically designed for use in situations where there is no neutral wire in the box, which is common in older installations in houses or apartments.

What do I need for ZigBee 3.0 switches to work?

For full functionality, you need a suitable Zigbee hub or control center that supports the ZigBee 3.0 protocol. Before purchasing, check whether your existing smart home already uses Zigbee and that the hub is compatible.

Can the module be replaced with other smart modules later?

Yes, in most cases you can replace the module with another smart module later if the wiring and space design in the box is compatible with the new product.

Can the switch also be operated manually without a smart app?

It is usually possible to manually control the switch without an app - physical functions are available, but for advanced setup and automation, we recommend using the Sonoff app or a customized app within the Zigbee ecosystem.

What should I pay attention to during installation?

Before installation, it is important to check the dimensions of the box, the suitability of the wall switch and its compatibility with the entire electrical installation. It is recommended to follow the manufacturer's instructions and, if necessary, seek the help of an electrical installation specialist.
