SONOFF TX Ultimate Review – A smart touch wall switch with innovative features

Sonoff TX Ultimate Review

SONOFF has been producing a wide range of new products over the years, and since the beginning of the year, the company introduced various new products and features including the iHost Smart Home Hub local hub which no longer requires cloud connectivity. The one we are going to review is the Ultimate Smart Touch Wall Switch (also known as the SONOFF TX Ultimate). SONOFF stated that they wanted to provide a new experience with their smart switch. Initially, we couldn’t imagine what new experiences a smart switch could offer. When we think of SONOFF, we usually associate it with affordable smart switches that are durable and perform as expected, not stylish or feature-rich devices. However, the SONOFF TX Ultimate comes as a complete package with light, color, sound, and touch. SONOFF has also expanded the touch area, so there’s no need to worry about missing the button while pressing it. […]
