Sensi Wi-Fi Programmable Thermostat 1F86U-42WF Review

    The good

    • Flexible temperature setting

      If you have a predictable schedule, it’s easy to program it in. If your schedule varies wildly by day, it’s easy to override the programming.

      The Sensi Wi-Fi Programmable Thermostat 1F86U-42WF has the ability to set up custom schedules, a different schedule for every day of the week or for week day/weekend and the temperature will definitely be kept constant.

      Some of the modules include: cool when working from home, cool when travelling among others. Optional 7-days scheduling helps reduce wasteful heating and cooling when no one is home.

      You can start with a preloaded schedule that reflects common daily patterns and quickly adapt it to your unique schedule, or you can use the intuitive swipe controls to build a customized daily schedule in seconds.

    • Intuitive and convenient application

      App can be configured to do everything that can be done by the Thermostat like change temperature, change schedule, check temperature and humidity, change from cooling to heating among others. In general the unit is able to do everything related to interest of the user.

    • Does not require C-wire

      It means this Sensi can be adaptable with many types of HAVC system. However, in case you have spare wire, I still recommend to connect the "C" wire to keep the wifi continuously working and avoid changing the battery. Which meant you need to go into the HVAC system and connect a spare wire to the common terminal in the system and the other end (blue wire) to the C terminal on the thermostat.

      The Sensi thermostat is designed to work with the existing wiring on gas, oil, geothermal, heat pump and radiant heat systems – up to 4 stages of heating and 2 stages of cooling. This wifi thermostat also enables users to use the old system as the thermostat can work well with older systems to achieve one compact functionality.

    • Only +/-1 degree swing range and humidity sensor
    • Easy installation

      Quick and easy installation in 15 minutes or less. The Sensi app includes a step-by- step installation guide and video tutorial

    • Extremely reasonable price

      Only within $100 and you can own a device which has flawless connectivity and totally stable.

    • Compatible with Amazon Echo

      Therefore, you can change the temperature with voice control. Just tell it what youwant. Especially, Amazon Echo can hear you from across the room with far-field voice recognition, even while musicis playing

    • Work with Wink (no Wink hub required)

      Wink is the simpler way to a smarter home. Start with connected products from your favorite brands and control them all from one app. And now, you also can control your house temperature from Wink without changing between many other applications.

    • Remembers programs through power loss thank to permanent on-unit memory
    • Beautifully simple design

      It has a height of 1.5 inches, a width of 5.5 inches when assembled and a display height of 1.75 inches. LCD display with clock, inside temp, outside temp, system status are arranged so logically and easy to catch.

    • Long term warranty

      It’s up to 5-year limited warranty with professional installation compared to normal 2-year warranty that most of other thermostats give you.

    The bad

    • Lack some features

      The Emerson Sensi doesn't have a very large selection of energy-management features. The unit lacks some of the advanced tools of other programmable thermostats, such as geofencing, auto-scheduling and a motion sensor.


    After all, the Emerson Sensi is commendable for its temperature-control features. Although you cannot use the energy-management, design and support features which other programmable thermostats have, this smart thermostat's simplicity still makes it a great choice for uncomplicated temperature control. It is a splendid device in terms of its design, installation,price and functionality and does not involve the user to be close the device to be controlled. If you are a fan of simplicity and stability or if you’re on a budget (or just don’t want to pay $250 fora thermostat), look no further than the Sensi.
