Zemismart Zigbee-kontaktmodul til 2 kanaler med energiovervågning – monteres bag lyskontakten, se effekt og kWh i appen (ZW-EU-02-PS, kræver nul)
Please note: this module needs a neutral wire and a Tuya Zigbee hub. It must be installed by a qualified electrician.
Make your switches smart – and see what your lights use
The Zemismart ZW-EU-02-PS is a compact 2 gang Zigbee switch module that fits behind your existing wall switches. Keep the switches you have, and add app control, voice control and schedules. It also measures power, so you can see the current, wattage, voltage and energy use (kWh) in the Tuya Smart or Smart Life app.

Why choose the ZW-EU-02-PS
- Keep your existing switches. Wire your one-way or two-way wall switches to the module’s switch inputs.
- Energy monitoring. See current (mA), power (W), voltage (V) and today’s and total energy (kWh).
- 2 gangs in one small module (51 × 53 × 21mm).
- Zigbee, so it pairs to your hub and stays off your WiFi.
- Timers, countdowns and power-on state in the app.
- Alexa and Google Assistant voice control.
App control
Add the module to a Tuya Zigbee hub, such as the Zemismart T1 or M6, in the Tuya Smart or Smart Life app. Each gang appears as its own switch you can rename.

Energy monitoring
Open Electric Stats in the app to see live current, power and voltage, today’s usage and the running total in kWh, plus a monthly chart.

Timers, voice and relay status
Set schedules, countdowns and random timers. Use Alexa or Google Assistant to switch each gang. Choose what each gang does after a power cut: off, on, or its last state.



Wiring
Connect live to L, neutral to N, and each light to L1 and L2. Wire your wall switches to COM, K1 and K2. Both one-way and two-way switch wiring are supported.

Pairing
- Make sure your phone and Zigbee hub are on the same 2.4GHz WiFi network.
- Power on the module and press and hold its button until the blue light flickers.
- In the Tuya app, open your Zigbee hub, tap Add Sub-Device and follow the prompts.

Frequently asked questions
Will it fit behind a UK light switch?
It’s 21mm deep, so it fits behind most switches in a 35mm or deeper back box. Shallow 25mm boxes may be too tight.
Does it need a neutral wire?
Yes. If you don’t have a neutral at the switch, see the ZB-EU-02 module, which has a no-neutral option (without energy monitoring).
Does energy monitoring cover both gangs?
The app’s Electric Stats page shows the module’s readings. The figures are for monitoring your usage, not for billing.
How much can each gang switch?
Up to 300W per gang, 600W in total. It’s designed for lighting, not heaters or high-power appliances.
Do I need a hub?
Yes, a Tuya Zigbee hub such as the Zemismart T1 or M6.
Can I fit it myself?
In the UK, work on lighting circuits must meet Part P of the Building Regulations. We recommend a qualified electrician.
