    It’s everything I liked about the Nest, and., July 14, 2014
    Earl Ax

    Verified Purchase(What’s this?)
    My review is mosty “versus the Nest” because I’ve had three different Nests and know that one well, and I like this one better.

    When my Nest died last month, I decided I was going to buy a thermostat from a company with a history of making thermostats work reliably.
    I would have installed this myself, but my A/C guy who installed my system and troubleshot my Nest two years ago … and then came back and troubleshot the replacement Nest last month said he would remove his loaner ‘stat and install whatever I decided to buy.

    The one feature of the Nest I knew was hooked on was the ability to change the temp from my phone. Sensi and several others do that now, so I had a few to choose from. In my research I learned that my primary complaint the Nest – that the temperature swing was too wide – was addressed by Sensi’s “cycle rate” setting.

    I like that the Sensi wall unit operates like a traditional thermostat. Nest’s no-button design is cool, but using a thermostat is not a lecture in UX minimalism, and black-and-chrome doesn’t really disappear into the background of my home (white trim and all).

    The Sensi is actually an easier DIY install than Nest (screw-down terminals vs. push in notwithstanding), and the main thing I would tell other folks is: install the app on your phone first and let it walk you through the installation.

    This, Sensi, is what I want in a thermostat. Convenient, reliable, programmable, understandable. I am okay with a modest premium for being Internet enabled. It’s half the price of Nest and doesn’t intimidate non-technical users. You can keep your auto-programming feature – I always fought with the schedule it created and with two young children we’re home most of the time anyway. You can keep your monthly energy usage report – it didn’t include enough detail to be useful anyway. And you can keep the space-odyssey design – it might be alright in the stainless-and-black kitchen, or media room, but it doesn’t work upstairs.

    Granted, we didn’t also install a second Nest to have more temperature sensors, and we didn’t buy their $200 talking smoke detectors which also report environmental statistics back to the thermostat. But I’ve got what I need from my thermostat now.

    P.S. It took the last Nest two years to go kaput, but I’ll update here if that happens to my Sensi.

    Update: After about a month I’m still very happy with Sensi. Most people won’t care about this but being a network security engineer, I’m impressed that the thermostat has exactly 0 open TCP ports, outbound communication is with one IP, and total traffic is very modest. Nest communicated with a whole bunch of different IPs and was much more “noisy” on the network. Good work, Sensi dev team.

    Chose White Rogers over Honeywell WiFi Thermostat, because it didn’t require any extra wiring., August 23, 2014
    Bob (Grand Prairie, TX United States) –

    Verified Purchase(What’s this?)
    Easy to install utilizing the app, that guides you step by step through the installation. You can load the free app prior to buying it and see the steps required, just search for Sensi.

    Has ability to set up different schedules. For example:
    – “Cool When Working From Home” – It basically keep the temperature constant throughout the week, since I’ll be home all day.
    – “Cool While Traveling” – Which raises the temp when my wife leaves for work and lowers it a 1/2 hour to her arriving home.
    The App allows you to do almost everything you can do on the actual thermostat
    – Change temperature
    – Change schedule
    – Check temperature and humidity
    – Turn fan to on or auto
    – Change from cooling to heating, auto or off
    – Background is blue when AC is running, gray when unit its off
    Thermostat has a backlight button, that is located on the top of the unit, which lights it up for several seconds.

    Overall this unit does everything most people would need to do from local or remote, using the app. Great product!

    Amazing design, beautiful remote access website, August 20, 2014

    Amazing thermostat, with great design! (This is the same as the UP500W, except it has a longer warranty, and is technically for contractors.)

    I tried the Nest, RadioThermostat, and a few Honeywell products before choosing this Emerson thermostat. It’s awesome!

    – Integrated hygrometer (that wasn’t really advertised in the specs)
    – Very sleek tactile buttons, extremely intuitive
    – Slim wall mount profile
    – Easy wifi setup & Android app
    – Nice SSL/TLS-enabled remote control via https://mythermostat.sensicomfort.com/

    – Intermittently I’ve noticed some wifi disconnections, though it automatically reconnects.
    – Scheduling with “multiple schedules” online seems a little finicky

    <tech details>
    This connects over 802.11n with a client MAC in 34:6F:92 (White Rodgers vendor).

    On the wifi side, I get random group key exchange timeouts, causing device deauths.

    The web UI is very slick, and looks like it was built by developers at SPARC. I’ll actually provide you some json objects including your thermostat’s battery voltage, the humidity, current AC/Heat run time, etc. if you dig around.
