    I wanted a thermostat that wasn’t trying to rule the world. While this thermostat doesn’t have all the bells and whistles of the latest smarter than the human AI thermostat, it is obedient and does what it is told. Simple settings and simple commands right from your smart phone. It does exactly what it is supposed to and nothing more.

    I had no C-wire and didn’t want to fool with running a power supply through the walls, so this was my only option. But I was pleasantly surprised! Easy installation…took me 1.5 hours, including removing the old thermostat, programming the new one, and spackling/painting the wall (very small and sleek unit). Operations is intuitive and easy via either the mobile app or online.

    This works really well. Operating the controls locally takes a little getting used to, but with the remote software controls, I never need to touch the thermostat. Syncs to my phone and allows me to control remotely by phone. And if you are a tracker like me, the best feature is the PC software, which allows you to monitor and track usage over the past week. (The phone app does not have this.) There is also a comparison to other users, but it’s not clear where those users may be. I show usage worse than 50% of the users, and that should not be true, since I never heat to higher than 68 degrees, unless the units being compared to are much further south. A map of units being compared would be a nice addition.

    After installation, the thermostat updated and lost the Wi-Fi signal. I reset the unit and regained the connection. In addition, it took a minute for me to get all the setting to where I was comfortable with it. I prefer not to use the scheduling, which seemed like the default setting. It is much better for me to use the fixed setting since we are a four-person household with different schedules.I did not like how the unit came packaged. There was no plastic wrapping around the unit itself or batteries. This gives the impression that you are not buying a new product. It is a better looking thermostat than most on the market. However, it could have a better feel to it. Overall, it is just a thermostat. I ordered black, which I think, looks more stylish. The optional back plate adds a nice look. The screen is a little retro. Maybe that’s what they were going for since the Nest looks like a digital 1950’s dial thermostat. It offers all the features I wanted. For example, option to use strictly batteries, controlled through Wi-Fi, and a lock out feature (wish it was password protected). The geofencing is a nice touch. Therefore, I ordered a second one for the upstairs.You can’t beat the price for all the features it has to offer. I have friends that purchased the Nest. Some of them are annoyed with it. Moreover, I think the prices are a little outrageous for the other Wi-Fi thermostats on the market.Update-mine works with Amazon Echo without the C wire hooked up

    This is a very good product. I have an off-grid cabin and this product keeps my cabin heated as I want. This is not a smart device but I like to call it an intelligent device. It faithfully keeps my cabin safe from freezing even when there is no electricity present. When the power is on the unit communicates with me via WiFi. This is great. I can control the temperature in my cabin from my home. Customer service is good. I really like the fact that this is a US company. The price is right for what you get. Remember this is not a smart device, it follows a pre programmed heating pattern you control. The WiFi connection is the cats meow! I paid just under $100 for my unit. Can’t say enough good thing about this product.

    Have had this installed for about two months now and have no complaints. This replaced a top rated Honeywell we bought to replace the smart thermostat provided by the power company. The Honeywell was constantly cycling on and off (like every ten minutes) so that one went back to the store after only two days. Research found this model to have a customizable temperature swing/offset. We have adjusted ours several times, ending on a .75. This works well for our 1970s built house with little wall insulation and the AC cycle times are back to what we consider normal. The app is simple to use and we are quite satisfied. We did not activate the geofencing so I can’t attest to that behavior. I would definitely recommend this.

    I like anything that simple, I live in an old house where I don’t have a c wire therefore I have to use something that doesn’t require c wire which is perfect for me as this one is using battery, the build quality is subpar, the installation take minutes just removed the old unit and pop in the new. Easy scheduling and heating, telling you when your heater is on.

    This is really the only option out there for replacing a two wire thermostat (no power wire) with a Wi-Fi model. Get more than a full season on one set of lithium AA batteries. Works great and easy to use. The mobile app is really handy for turning up the heat before you head home (or turning it off if you forgot).

    Love this thermostat. I originally tried to install the nest 3 but it wasn’t charging without a c wire. Actually am very happy with the lux, still looks nice and works well on my iPhone X. Very easy to program and it also qualified for a rebate with my electric company. Lithium batteries aren’t too expensive and last awhile. I actually think it’ll be better for the life span of my boiler heater as the nest would need to turn it on intermittently just to recharge itself it if the boiler hasn’t been used for awhile.

    I’m a single guy that travels for work, and live in Wisconsin. Gone are the days I’m worried my pipes are going to break in the house when it’s -30 outside. A quick click on my phone and I can see the inside temp and adjust as needed. I love the history of my furnace’s running time per hr, and the app is great. I love this so much I immediately bought another for my garage, and monitor them both, independently from the app. Peace of mind while gone, and lower costs, and no more, “crap I left my thermostat set too high” once you already left.
