SONOFF TX Ultimate “T5” smart touch wall switch support gestures, custom covers

Sonoff TX Utimate TX Smart Touch Wall Switch

SONOFF TX Ultimate smart touch wall switch, also known as the SONOFF T5, is another wireless switch from the company with up to 3 gangs, RGB color edge lights around the 86x86mm switch, as well as support for gestures and custom covers. Gestures like swipe left or right are possible because the full area of the SONOFF T5 switch acts as a touch sensor, and the RGB LEDs around the device enable ambient lights in the room at night. The switch can also provide haptic feedback to the user during use with a built-in speaker and vibration motor. SONOFF TX Ultimate specifications: Model numbers – T5-1C-86, T5-2C-86, T5-3C-86 depending on the number of buttons Wireless – 2.4 GHz Wi-Fi Input and Output power 1-gang: 100-240V~50/60 Hz up to 5A 2-gang: 100-240V~50/60Hz up to 10A (5A per gang max) 3-gang: 100-240V-50/60 Hz up to 15A (5A per gang max) Dimensions – […]

SONOFF MINIR4 review – A Tiny WiFi Smart Switch tested with eWelink app/web, and R5 controller

In this post, we’ll review the SONOFF Mini Extreme, also known as MINIR4, WiFi smart switch based on ESP32 wireless MCU by installing it into a wall-mounted light switch box and controlling it with both the eWelink mobile app for Android and the SONOFF R5 scene controller. SONOFF MINIR4 Installation We’ve already gone through the specifications, unboxing, and teardown in the announcement, so I’ll get straight to the installation part. Note this review was done with a light switch “box” (about 11x6cm) in Thailand, so your mileage may vary. The first challenge is that contrary to the similarly-sized SONOFF ZBMINI Extreme Zigbee switch, the MINIR4 WiFi switch requires a neutral cable, and most lights in Thailand are wired without a neutral wire, so I had to get the neutral wire from the outlet switch box underneath. When I call those “boxes” there are really holes in the wall here… Wiring […]
