Amazon Smart Thermostat – Save money and energy - Works with Alexa and Ring - C-wire required

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.

I’ve done a few small electrical projects as a 31F and this was by far the easiest. The instructions are pretty clear. I wish the faceplate guidance and optional usage was a little more clear. However, the install went great. We replaced our old Honeywell and this wiring matched up perfect. The app was responsive and quick set up. It looks great on our wall and much more modern. 10/10.

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.

Latest Edit #3 (upgrade to 3 stars): just FYI… Amazon customer service will contact you if you leave a bad review. lol I didn’t have time to spend with them on the phone, but I kept fiddling with these thermostats until I finally have a reasonable setting. The interface in the Alexa App is somewhat confusing. Imagine that! There are two different “auto” modes. One is a scheduled mode for temp ranges pre-set in 3 categories of home, away, and sleep. That’s your only choices. You must preset the preferred temp ranges and make a control schedule and set it to auto. This differs from the auto control choice which uses hunches to automatically change thermostat to the preferred temp ranges set for home, away, and sleep. If you choose the hunches option, it will not work correctly unless everyone in the house connects their smart phone to the thermostat so Alexa can “track you in the background” (bad idea) to determine through hunches whether anyone is at home or everyone is sleeping. That just does not work for me. Thankfully, I don’t feel like I completely wasted my money, but these thermostats only get 3 stars because: 1) the Alexa app (always trouble to find/control anything) is particularly cumbersome for these devices and confusing to navigate. 2) the inability to set a true time schedule at a specific temperature which can hold automatically. 3) no option to create a custom temp range other than the 3 offered. PROS: the thermostats are streamlined and look nice and are reasonably easy to install if you have basic electrical knowledge. If you don’t, you’ll probably need assistance from a professional. The auto switch between heat and AC to keep the temp range is nice. You can control it well from your phone with the Alexa app. Having their own app which is easier to navigate might be helpful. Controlling the thermostats by voice through the dot or echo (as with all things) is hit and miss. Edit #2 - After fiddling with these things a bit more, I came back and reduced this review from 2 starts to 1 star. Awful! Can’t get rid of the darn “hunches” setting even after turning it off. Argh! The auto range to set temps whether in the Auto setting or with a schedule does not allow for heat and cool temp to be set close enough together. You’re constantly either on too high of a setting for cool or too low of a setting for heat. You never have a truly comfortable setting. 1st review: You are stuck using temperature ranges for Home, Away, or Sleep functions without the ability to SET a specific temp at a certain time. The old thermostats I had where I had to manually go through and set a schedule at least kept my house reasonably comfortable. With these so-called smart thermostats we are either too hot or too cold because the temperature ranges will not allow us to set it where it’s comfortable. In the end, this thermostat is not really that smart and makes me feel dumb for buying not one, but two, of these things. I will probably just end up reinstalling my old ones again. Ugh! What a waste of money because I can’t send them back since I’ve been trying to learn to use them, and my return window has closed.

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.

The Alexa thermostat is the 4th thermostat I’ve had installed in my house – one with Forced air, gas furnace and a C-wire — including a basic thermostat, WiFi Honeywell , Google Nest and now Alexa Smart Thermostat. I learned a lot about HVAC wiring and thermostats , and realized Alexa is the best smart thermostat package right now because of it’s more traditional wiring & switching hardware ( for those using C-wire connection), high contrast & responsive display, broad smart home features and sleek fit & finish. For $80 you can’t go wrong. For those with or without Alexa, I believe it’s the best thermostat when you look at the clean fit & finish, convenient smart home / remote features & reliable , traditional wiring system. Google Nest uses creative circuitry to accommodate more wiring setups, which can affect longevity. Nearly all of the complaints from earlier reviews have been addressed, with the inclusion of multi-room temperature measurements, daily schedules, device sharing , reliability and more. In 2026, you can be confident this is a reliable and mature smart home device. Hardware Installation Hardware is very easy for any DIY’er. Use a piece of paper template and your fingernail to trace out the screw holes so you can mount and align placement on the wall. Mine was aligned next to a security keypad so I wanted the leveling to be perfect. It can be challenging to fit & bend all of the wires into the tiny terminal pocket , but once enclosed the wall installation is very clean. Smart Home Setup Software setup is easy, even when bypassing the QR code. I recommend skipping to the test phase and doing the complicated setup steps after you get accustomed to the device. Alexa app & setup has become very reliable and polished. I did the “hard” setup flow and it took about 2 minutes end to end to configure the WiFi, wiring, thermostat ranges and more. I recommend turning on fan circulate in any home less than 20 years old , which is usually required by code. That helps bring in 10% fresh air periodically. Support for CIRC / circulate on this thermostat allowed me to remove a legacy mechanical fan blower timer that had been unreliable . Fit & Finish Despite being a more humble build, I found the installation to be more preferable to my Google Nest. Alexa Thermostat is a simple matte white, with very clear , colored icons for Auto , cool, heat & fan-circulate. It’s very easy to read and the touch buttons are intuitive. Although Nest thermostat’s mirror finish is fancier, the UI is overly complex with counter intuitive swiping. Software Experience. The Alexa App UI can be a bit complex with many layers of settings, but once the device is setup with temperature ranges, fan setting, hunches and more – your primary experience is a virtual thermostat screen. It works well throughout and away from home. It’s especially convenient with other Alexa devices. Voice commands and queries via Alexa are trivial. It’s nice to change temps at night via whisper. Electrical Concerns Electrical connectivity & longevity is the most important advantage of the Alexa Thermostat. You can hear the traditional relays that click on and off in the thermostat, though they are more subtle than a budget device (I tested the sound before vs after). This design should last 10+ years compared to other smart thermostats, and maintain the life of your furnace/HVAC logic board. other smart devices “steal” power over the circuit , which generates heat and wear . 2026 Conclusion I held off due to some mixed reviews, but all of those issues have since been worked out. For the price, you won’t find a better feature set, and I’m expecting reliability to be very good at least on the HVAC wiring.

Couple of things I learned the hard way, first don't hit the middle circle button on the thermostat to check what you have your temperature set at because that action turns the fan from automatic to on all the time. So even if your unit is not running, the fan will just continuously blow air. Second, I wish amazon gives you more control for adjusting in the app. Like setting a whole degree difference between when the heater kicks on and when it kicks off (ie. if you set it at 70, unit kicks on 69 and warms it to 70). Currently the unit kicks the heater on and off at the degree you set it on. However, placement of my thermostat is in a drafty hallway and turns on and off way too often. I counted one night turns on for 4 mins then off for 4 mins before kicking on again, so within one hour it cycles more than 7 times!
