I’m a big Nest fan had it on my old house the problem that I have with them it’s the cost, and even with gas company great rebate didn’t justify the cost especially with my new home having a total of 5 thermostats (t-stat). I was excited when I found that Amazon partner with Honeywell to get this t-stat created as Honeywell has been creating t-stat for years which make me feel better when making the purchase. ---COST--- Now let go over the details for cost it’s good and I got two of them which at the end of the day will be free due to the electric company rebate for a smart t-stat. I didn’t get a C- adapter and I will explain later (INSTALL session) why I purchase a 24-volt transformer for my first-floor unit. ---INSTALL--- Love the package it reminds me of the NEST when it first starts came with everything that you needed the only additional tools, I need was a harmer, and drill but this is normal for these installations. Now the biggest question that everyone has is the C (common) wire. This is where you need to do your research regardless of what company you go with when upgrading to a smart thermostat, due your homework on what you need. For me I have a spill unit (boiler & A/C) first for my second-floor unit it was super easy I had an extra wire and I use it for Common the t-stat startup and finish within 30 min. Now for my first floor I utilize a 24-volt transformer because I didn’t have spare cables and I didn’t want to run a new cable which drove me to make the purchase again do your homework before and see what option best works for your use case. I connected the transformer to the C wire and the other end to Rc and that works like a champ. This is critical if you have a split unit since Honeywell power their t-stat via Rc only when you have two RED Wire (R (heater) and Rc(cooling)) and the blue tab (internal jumper is down position. If you only have one RED Wire you are fine just keep the blue tab up and your t-stat will turn on without any problems. I did reach out to Honeywell and explain to them they need to explain this on their site and white papers that when you have split units’ power for the t-stat will come from Rc and not from R this is critical because my house previous owner installed a switch to keep the A/C unit down through the winter to avoid accident turning on the unit which is great idea. Please keep in mind this is NOT an Amazon problem that is Honeywell they did acknowledge their mistake and agree to update their site and documentation. Running my transformer cable and installing the unit took me about 60 minutes because I wanted to look perfect with the transformer cable going through the wall this make the installation look cleaner. ----SETUP---- Once all wire were connected the setup of the t-stat was simply and when I say simple it was super didn’t have input the WiFi password or anything else since it automatic joined my account that was amazing and simply just like setting a fire table that was a great experience. Amazon did an amazing job doing this some users this my not be as good, but I look automation the less click I must do the less chances of mistake A+ ---LOOK--- The t-stat looks great after the final install the wall panel (included but optional for install) made it easier for me since I didn’t have to paint (if you had a different color paint I would recommend adjusting before completing the install but that is just me) ---Interface (GUI)---- For me the GUI is great for some it my but I’m one of those people that like to have one application on my phone or tablet rather than 2 and this is where Amazon did another amazing job. Please keep in mind that Google who purchase NEST is doing the same thing I see the NEST application going away in the future all new NEST is configure from Google Home and they also did a great job The GUI it’s simple and allows you to setup multiple schedules and copy them to different days or week. Huge plus on my book because for the NEST I had to do manually per day I can setup one day and copy to another. You can setup away and home schedule or utilize your current Amazon device to tell the t-stat that you are home or away. Another item that I love from the Amazon you can setup MAX cooling or heating this allows for mistake not to happen and getting your house too hot or cool really go option to have and you can set filter replacements without your assistance (optional) for me this is great no more remembering air filter as they will show up at my footsteps. Energy saving incentives can also be done via the application. The dashboard its great too it tells you how much energy you utilize each day and where you can save. Now the only downside for that I experience is only scheduling session on Android because it forces close my Alexa application all the time, I don’t have this problem with anything else on the application just the scheduling session. This option works perfect on my wife new iPhone and iPad pro and new Android phone. My old Android is the one with this problem, but I experience this kind of thing on and off since it’s an older device. -------Final judgment ---- The device is good option for a smart t-stat and would recommend for anyone some of the problems that were reported it was on day one which is expected with any new launch overall I see this t-stat giving Google (NEST) and others a run for their money as now you have a great option for smart t-stat and you don’t require to break your budget to acquire one. In addition, love the one application for everything as previously mentioned all big companies are doing this model to stop the install of some many other applications. In a scale from 0 -10 this t-stat gets a 9 please note that the NEST 3rd gen got a 9 from me. Hope this helps everyone make the correct decision and I will update this review in a few weeks to report back.

Integrates perfectly with the rest of my Echo devices. It is so convenient to control the thermostat with voice commands. Programming is very easy and multiple times and temperatures can be set throughout the day. Installation was very easy and the box looks modern.

UPDATE 12/27/21: After a month it would fail to turn on the outside unit of my heat pump, only the inside unit, despite audibly clicking twice, and the Alexa app would say "Delayed start", as if it were on a cooldown timer, which the unit was not. This would happen both on scheduled times of temperature change and when manually changing it. Turning the breaker off and on would resolve the issue for a few hours before it would reappear. I ordered a replacement unit thinking that was the problem, but it did the same thing. I put my old "dumb" digital thermostat, the Lux TX9100E, for which there is a newer version (Amazon ID B00CX2QA3Y), back on and I haven't had a problem since. Changed star rating to 1 and will say to avoid this thermostat, it's not worth potentially risking damage to your system, especially when all of the issues mentioned in my original review were not addressed before the much larger issue occurred. ----------------------------------------------------------- ORIGINAL REVIEW: This review pertains to the unit with Device Software Version 16843520 and Manufacturer Software Version 16844544. This is my first venture into a smart thermostat. I've wanted a Nest or one from Honeywell for a while, but their high price tags put me off. Enter the $60 Amazon Smart Thermostat. Installation was fairly easy, I say fairly because since the thermostat is small, the wiring can get cramped. The optional included backplate is quite large, which is a GOOD THING in my case as it easily covered several holes from previous thermostats. Connecting it to Alexa is also easy, just tell it to discover devices and it proceeds smoothly. There are a few negatives though. I waited 10 days to write this review hoping they would release an update that would fix them, but so far they have not. 1) It has issue reconnecting to the network after a power loss. I had to pull it off the wall (it clips on to the mounting bracket) and put it back on to get it to reconnect after a few seconds long power failure today due to storms. My router is connected to a battery backup so it never lost power. 2) The scheduling is very basic. You can only set 4 fixed temperature types (Work, Home, Away, Asleep) and assign them to certain times, and you can't adjust them differently. For example, you can't set 5AM and 5PM as "at home" and set the 5AM to 65°F and the 5PM one to 68°F, they both have to be the same. Also, as of this review anything you put in the Heat and Cool choices is changed by whatever you put in the Auto section, so it's only really possible to use it with Auto. 3) Voice commands don't work well, or at all. When you say "Alexa, what's the inside temperature", it will often say "Thermostat does not support this function" when it does, same goes with humidity. Also when you say "Alexa, raise the temperature by 2 degrees", it may not work correctly, the last time I did that I wanted to raise it from 66°F to 68°F and the air conditioning came on because it had set the temperature to 64°F. There are also functions which are unable to (yet) be controlled with voice commands, such as turning the fan from Auto to On or Circulate, you have to use the Alexa app to do it. 4) The display. Currently it will cycle between the Active and Inactive brightness at random, even when there is nobody and no sound in the room. 5) This is a critical bug. About half the time when the heat is engaged it will also use supplementary heat (I have an electric heat pump with electric aux heat), even if the temperature outside is above 50°F, and it is just coming on to maintain temperature and been raised multiple degrees manually. Disconnecting the W2 wire fixes this, but also disables auxiliary and supplemental heat completely. 6) There is no display for auxiliary heat in use on the thermostat nor in the Alexa app. Considering aux heat, especially on electric heat pumps, uses a large amount of energy, there should be some kind of display or, preferably, a popup notification.

Replaced my old Honeywell thermostat with this smart device. My old thermostat was tested to be not accurate in sensing the current temperature and usually triggers start/stop of my furnace or AC at +/- 2 degrees of current room temperature. This amazon smart thermostat may not be as smart as others on the market (such as Nest, EcoBee, etc) but it does the job well, easy to control from your phone thru Alexa app and it does not break your bank with a reasonable price. Btw, my local utility PG&E company is giving me a rebate making this purchase completely free. My house does not have a 5-wire cable connection from my furnace/AC to the control location in the hallway. Instead of ripping it out to put in a new 5-wire cable and all the extra work of patching up the walls etc, I decided to install it with the G (green) wire to be the C (central) wire and short connect the G (green) and Y (yellow) terminals at the control board of the furnace system. You may search for this method on Youtube as there are lots of video clips showing this method. CAUTION: Note that you must be comfortable working with the wires at the furnace system control board, and make sure that you switch off electricity at your main control circuit panel to avoid damaging your furnace/AC system components. If you are not comfortable, you can hire a professional to do the job for you. Installing the thermostat over the existing location is quite easy and straightforward. The package provides everything (a face plate, the screws and anchors, mounting bracket). You will need a drill to properly put in the anchors for the whole assembly. The wire connection to the assembly is made easy using the connectors spring clips (instead of the old screw methods of connection). The amazon web link for the installation will walk you thru all the steps, connecting it to your home wifi, and testing it out the furnace/AC system once done. Connecting the thermostat to the Alexa app on your phone is simple as it is quickly detected once your thermostat is connected with your home wifi. But navigating the Alexa phone app can be quite intimidating since there are so much more option and setting to set up. This is due to Alexa being a hub to allow control of many other smart devices that may exist at your home, such as smart outlets, smart bulbs, etc. I only give 4 stars to this device since it only allows 3 setting profiles: Away, Home and Sleep. For most usage, 3 would be satisfactory but I need more than 3. As this is a software function, it can certainly accommodate your individual creation of your own profile with your chosen name and integrate them all into the control of your furnace/AC system. Other than this little inconvenience, I am happy with the product and would highly recommend it.

Another exceptional product from Amazon. I am very pleased with my thermostat; it operates flawlessly and is significantly superior to my previous thermostat, the Amazon thermostat activates my air conditioning immediately, while the other one had a delay. There are numerous options available for both heating and cooling controlled through the app, far too many to detail. However, I will focus on reviewing the product: it installs seamlessly and connects to your Wi-Fi without any complications.

1000% REQUIRES A "C" WIRE if you are upgrading from a Nest or other thermostat that did not need one. Straight forward installation. A socket labeled "G" is above the "C" to plug in the continuous 24Volt power so be careful that you do not confuse them because plugging the 24Volt wire into the "G" socket will not make the thermostat work; it won’t harm it but it won’t work until you corrected. ~Yes, I committed this faux pas and no, the thermostat did not work until I fixed this after taking a closer look, when I thought that my idea of a 50-50% shot on two labeled "C" sockets did not make sense design-wise as I do not believe there is a good reason to daisy chain continuous power on the "C". This thermostat will blend into a white wall and is quite unobtrusive even if your wall isn't white. A large covering base plate is included if you like the look or have a lot of sins to cover up. It felt very solid on the wall and the setup, via the Alexa app was very clear and straight forward. Display is on the low powered side. Getting the socket out of the thermostat is a bit tough, but you can do it with a small bladed screw driver, or the tool that they provide. Integrates to Alexa Needs Alexa app to install it It works and provides smart and remote programming. Price point is 30% that of the Nest newer generation thermostats. Sub $80 USD vs $250+ USD

-- Update -> 10/23/2023 Amazon reached out asking for feedback... hopefully somethings will be improved in a future software update: 1) Buggy nature of getting stuck in a mode - potentially due to preferring to adopt the current settings whenever the settings are changed via the app (i.e. heat and fan was on when i saved the settings, so now the fan and heat becomes always on) 2) Fan stopping for a second and then starting back up (probably when transitioning between heat and circulate air) 3) Alexa app being really busy - all i want to do is use my thermostat 4) Inability to control how long or how often circulate air kicks on 5) Easily see the hours on the filter --- Currently it works but not all that impressed, i should have gotten something 'better'. The old thermostat liked 30 seconds heat/cool cycles... so i figured i'd get a 'smart' thermostat... During the first day, I've ran into the fan being stuck on (fixed by going to the alexa app and cycling through all of the options and leaving it on air circulate) and heat being stuck on (fixed by going to the alexa app and turning it off and then back on). We now use the same temperature settings all day and night so maybe that helps. We do have some hotter and colder spots in the house so the air circulate option (runs 15 minutes or so an hour, every hour) helps a lot. But read what other folks are posting, this device is not 'smart' enough... my dumb 2001 thermostat didnt stop the blower fan and then turn it back on after a half second pause... but that seems to be the only thing it seems to be getting wrong now. It just did it again... i think its switching between heat and air circulate modes and does so by turning everything off and then back on (@Amazon - can we get a bug fix please?) Installation is easy enough, really nice to turn the temperature via the App whilst still in bed... talking of the app, wow, all i want to do is control the temperature buts buried along with a turn of other stuff i dont want to see. Now if i can figure out how many hours the current filter has so i know when to replaced it then maybe its worth another half a star....

This took less than 5 minutes to set up and get into my routines. Checking the compatability prior made the hassel of this, non-existent since I had an older Honeywell thermostat, So all i really had to do was snap on the new face. Extremely pleased with the auto feature that keeps my temps within my comfort zone. It's not too big, low profile, pretty accurate, and immediately started to work. I also like the brightness feature as my last was blaring at night. Very happy with my upgrade. Thanks.
