## Description

Save energy and money with desertcart Smart Thermostat

Review: desertcart Smart t-stat honest review - 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 desertcart 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 desertcart 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. desertcart 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 desertcart 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 desertcart device to tell the t-stat that you are home or away. Another item that I love from the desertcart 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.
Review: Amazing value compared to professional solutions - I have two separate HVAC systems at home. One of the thermostats is installed in the hallway, and unfortunately it’s affected by airflow from the other HVAC system. As a result, the temperature reading is often inaccurate and the system doesn’t work properly. A paid technician suggested replacing it with a smart thermostat plus two remote sensors placed in the rooms that actually need temperature control. The quoted cost was around $600, which felt way too expensive. Then I found the desertcart Smart Thermostat. By pairing it with two Echo Dots I already owned, I was able to achieve essentially the same functionality: controlling the temperature based on the rooms I care about for only about $80. Setup was straightforward, Alexa integration works great, and the temperature control is now much more accurate and comfortable. I’m honestly very happy with this solution and impressed by how much money it saved me. Highly recommended if you’re looking for a smart, budget-friendly alternative to costly professional setups.

## Questions & Answers

**Q: Why would I need a C-Wire adapter?**
A: Pull out your current thermostat before ordering! Mine only had 4 wires hooked up (battery powered with heat and AC) but there were 4 other unused wires in the wall. In my case the unused black wire was the C-wire (common wire) which was not hooked up to my battery powered thermostat. So I didn’t need the adapter even though some of these “answers” said I would if I only had a 4-wire system.

**Q: Can I use multiple thermostats in same house?**
A: YES,
I just installed and set up 2 of these for my own house using only the Alexa App on my phone. 
I am a Licensed HVAC contractor in WMD Area but it is pretty straight forward installation for anyone.

Take a picture of where the wires connected on your old thermostat, connect them to same ones on this one.
TWO THINGS;
1- Just pay attention to the warning label on the wiring cover for heat pumps about W terminal.
2- FOR HEAT PUMPS ONLY, O/B is pre-set for O(Energized in cooling) some heat pumps, Ruud, Rheem, Mr. Cool Ducted Mini Split, Carrier Ducted Mini Split, etc. Units use B(energize in heating) make sure to check your heat pump..
 
To set-up for multiple heating cooling systems, you just have to pick a name for each one from pre selected list or create a custom one based on your heating/cooling system. You can then adjust the time and temperature schedule for each day of the week based on your schedule.

It works with Steam or Hot water Boiler and COMBI Boilers, but you need at least 3 thermostat wires.
RED         to R terminal for  HOT on 24Volt side of the  control transformer inside the heating system.
WHITE    to W terminal for HEAT. 
3rd Wire to C terminal or COMMON side of the 24 Volt Transformer, you may need a professional to do this if you don't have an existing one.

As always; TURN POWER OFF TO ANY APPLIANCE RUNS BY ELECTRICITY.

I hope this was helpful.

**Q: Will you be able to use remote room sensors?**
A: I would definitely consider this Thermostat, but it doesn't work with remote sensors. We have a single level ranch and I have 3 sensors hooked up to my Ecobee thermostat.  For instance, at night the wife and myself like it cooler than most, we set the thermostat for 67 degrees, but with the sensors, I can set all of the other sensors (including the Ecobee) to off except the one in the master bedroom.  That way the master bedroom will stay at 67 degrees.   We also have one in my wife's home office, so during the day when she's home alone, only her office will be at the set temperature, not the entire house.

**Q: Can I set the thermostat to change to different temperatures at different times of day on different days of the week?**
A: Something to consider if you want more than 3 temperature options (Home, Away, Sleep) is to set up routines.  Set the routine(s) to a schedule (Days of the week and times of day) and tell it to set a specific temperature on the Thermostat.   You could run all your thermostat schedules via routines or (I assume) in addition to the basic (3 tempt) Thermostat schedule.   It's more work than I'd prefer but it is an option.

### ⭐⭐⭐⭐ Great thermostat, not so great instructions..
*by A***W on December 3, 2025*

I love this thermostat (once I got past installation), especially compared to my old one. There’s only three buttons on the device, which are easy to use. My favorite feature is the automatic mode, where you set the temperature range, and it will heat and cool accordingly. I don’t want to use voice assistants, etc., so I disable those. I was worried this would hinder usage of the thermostat, but thankfully you can use the app controls/manual buttons with the voice options disabled. The only downside is the instructions, which were quite difficult for someone who hasn’t installed a thermostat before. It’s almost there, but I think the wording for the instructions is a bit vague and could be easily clarified to make the installation process easier. I am renting, and didn’t know what to look for as far as the heating mode, labels with more than one letter, etc. - the instructions were designed very vaguely. Thankfully Reddit was able to help, because the errors given in-app also didn’t give any details on how to fix the problem or what was throwing the error message. Overall, I would recommend the product, especially at the price point. My energy company has a reimbursement program that will cover this entirely. This purchase is a no brainer for me!
