The SmartWise T4 EU UNI (R3) smart switch is the latest, third-generation (R3) universal type of the switch family. It is recommended to be connected with a phase + neutral wire, but it is also suitable for connection without a neutral wire, only with a phase wire, so it can be connected in place of all conventional switches. In the case of a zero-wire connection, it is only recommended for switching on lamps, it is also compatible with: tungsten torch, LED and compact fluorescent lamp (CFL). Only in the case of connection with a phase wire, it is necessary to connect a small flash adapter module (included with the product) to the lamp.

It is equipped with an elegant glass front panel and a highly sensitive touch switch, with the touch switch you can of course switch the lamp on the wall, just as you would with a traditional switch.

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

Thanks to its built-in WiFi chip, the eWeLink app running on an iOS (Apple) or Android mobile phone with an Internet connection can be used to remotely control the on/off of the light switch and set a timed on/off. There is also a time relay function in the switch, as in most other Sonoff and SmartWise devices, you can set it to automatically turn off for a specified time after switching on, so that the light does not stay on unnecessarily.

Remote control can be shared with others, such as family members.

The perfect solution for smart control of any lamp or lighting. With its use, you can comfortably turn on or off the desired lights from a distance, even when you are not at home. Used as a break-in prevention solution, we can program it to turn on or off so that the outside world thinks we are at home.

Thanks to its built-in RF 433MHz receiver, SmartWise can be remotely controlled with wireless RF wall switches and RF433 radio remote controls. Used together with wireless wall switches, it can be used for alternate and crossover switching. The individual buttons of the switch can be paired separately with the wireless switches and remote controls, the individual circuits / buttons can also be paired with other wireless switches in any way you like.

The SmartWise T4 EU UNI (R3) smart switch is available in 1, 2, 3 and now 4 circuit switch versions. Available in white and black front versions.
