Sensi Touch Wi-Fi Smart Thermostat with Touchscreen Color Display, Works with Alexa
The Sensi Touch ST75 adds a vibrant touchscreen color display to the proven Sensi platform. The 3.5-inch screen shows temperature, humidity, and schedule at a glance — a significant usability upgrade over the button-based ST55. It maintains Emerson's strong data privacy stance and broad voice assistant support including Apple HomeKit, which many competitors lack. With 14,120 reviews and a 4.5-star rating, it is one of the highest-rated smart thermostats on Amazon. The caveat is the C-wire requirement, which the cheaper ST55 avoids. In our testing, the touchscreen was responsive, the colour display was easy to read from across a room, and the scheduling interface was intuitive.
