SmartWise T4 EU UNI (R3) smart light switch series is the latest, third-generation (R3) universal type of the wall switch family. Recommended wiring is live (phase) + neutral wire, but it also supports wiring with a single live wire, without neutral wire. It's a truly universal solution, which can be installed into any European wall boxes, with or without neutral wire. In case of single-live-wire installation, manufacturer suggests to use it to control only lights, compatible with: Tungsten torch, LED and compact fluorescent lamp (CFL). In case of live wire only installation, it is also necessary to connect a small anti-flicker module (included with the product) to the lamp.

It has an elegant glass front panel and a sensitive touch switch, which you can use turn tunr on/off the lights just as in case of a traditional wall switch.

Just like Sonoff's smart switches, it uses the same eWeLink app and platform, so it can be nicely combined with other brands using eWeLink app, such as Sonoff, SmartWise, KingArt, WDYK and Woolley.

Thanks to the built-in Wi-Fi chip, it connects to eWeLink cloud and you may remotely check the switch on/off status and turn on/off the switch using the free eWeLink app, running on an iOS (Apple) or Android smartphones, all you need in an active Internet connection on your prhone. You may also set scheduled on/offs, and also use time relay feature of the switchto set automatically turn off for after a specified time (also called as inching), to save energy cost by this auto-off feature. Remote control can be shared with others, such as your family members.

It's a perfect solution for smart control of any lamp or lighting. You can use it to remotely control the lights, even when you are not at home. You may also use it a security solution, by programming to turn on and off, so show the outside world that you are at home.

Thanks to its built-in RF 433MHz receiver, this SmartWise switch can be remotely controlled with wireless RF wall switches and RF433MHz radio remote controllers. By using together with wireless RF wall switches, you may set up two-way / three-way etc. switching easily and wirelessly. (In case of multi-gang switches), individual buttons of the smart switch can be paired one by one with the wireless RF switch or remote control buttons, with great flexibility. 

New features of R3 UNI version, compared to previous R2 version: 

• universal wiring: it can work with single-live-wire or with live+neutral wiring;

Please note that this product comes with a small anti-flicker module, included in the product box. In case of wiring the switch with live-wire-only (no neutral), then this anti-flicker module needs to be installed at the controlled electric device (e.g. lamp or bulb) to the live and neutral wires.

In most cases the switch with single-live-wiring cannot work without this small module installed, or it may cause the lamp to turn on/off randomly or the light may flicker.
