Sonoff TX, introduced in the summer of 2019, is the latest member of Sonoff’s smart light switch product line. It controls three lights or a chandelier.

Compared to former Sonoff T1 only the front panel got a new look, beside white, now black and 3-gang version is also available. Like the former one, this device is also features an elegant glass front panel and touch switch on it. Due to its built-in WiFi chip you can remotely turn ON / OFF the switch with a smartphone app (iOS or Android), and with the timer you can set a single or scheduled turn ON/OFF too. By using the touch switch you can certainly turn on the light also at the wall, just like with a traditional light switch. Remote control can be shared with your family. It is a perfect solution to smart-control any lights and lamps. By using the smart switch you can remotely turn ON / OFF any of your lights even when you are not at home. Using it as a housebreak-prevention solution you can set a scheduled turn ON / OFF to pretend you are at home.

TX T3 version (similar to former T1) features a black glass front touch panel. Like Sonoff T1, it comes with built-in 433MHz radio control, that allows pairing with a remote radio-control, and SmartWise radio-control switch, thus connecting alternative switches to wired switches without further wiring.

Since the v3.5.4 version of eWeLink app the switch can be set to impulse-mode, or to automatically turn off based on a schedule (stairway-mode).

On the elegant glass front of TX T3 EU the touch switch is nearly invisible while the switch is turned off, lights with 90% while turned on and with 30% in standby mode.
