Honeywell Wi-Fi Smart Thermostat

Stands Out or Blends in

The Honeywell RTH9585WF1004/W is one of those electronic thermostats that really takes advantage of just about every advancement in its field, essentially putting the "smart" in "smart thermostat". What you get out of it is nothing short of impressive on just about every level.

But despite the numerous control functions (the bulk of which we will cover in a moment), the thing we like most about it is the display. The whole thing adds up to precisely 3.5 x 4.5 x 0.88 inches in overall dimensions, so it isn't necessarily the smallest option on the market right now.

That being said, the relatively large size is in no way a disadvantage. It has that high-tech, sleek appeal that really blends well with a contemporary or modern home. The silver framing gives it a sharp and professional look. And if you don't like the default background of the model's menu, you can program the bright customizable screen to match the surrounding décor, so it won't stand out if you don't want it to.

The aforementioned numerous control functions are really the only downside of this product. Well, it isn't a downside per se, but you'll probably have to spend some time figuring out the settings, even if you have plenty of experience with these things. Once you do figure them out though, there's a lot that you'll be able to do with this remote control thermostat.

Review of Honeywell Wi-Fi Smart Thermostat

PRETTY INTELLIGENT

Now, as for those features, in no particular order, we would like to start with the Smart Response technology. What's great about it is that, in addition to the usual 7-day temperature programming, you can rely on this technology to learn your heating and cooling cycles and deliver the ideal temperature at the right time based on those cycles.

The Intelligent Alert system also deserves some recognition. You can program it to receive alerts and automatic updates via email. It will send you air filter change reminders and humidifier pad replacement reminders. You can set the system to receive temperature warnings or to notify you about the changes in the Internet connection status.

The thermostat automatically updates to daylight savings time. It will also display the daily weather forecast on your screen. What's more, the Honeywell app will give you a 5-day weather forecast, so you'll be able to change the thermostat settings beforehand.

There are plenty of other interesting features, but the last couple of things we would like to mention are the Vacation Hold and Holiday/Event modes. Using these features, you'll be able to suspend the schedule while you're away on a holiday or set a specific schedule for this period of time.

All things considered, the Honeywell RTH9585WF1004/W might very well be the best programmable thermostat on the market today. The number of features is impressive in its own right, but it is their execution that allows this product to take the room-temperature cake.

ecobee3 lite (EB-STATE3LT-02)

Save Your Funds

The Ecobee3 lite Smart Thermostat is the kind of model that has all of its advantages put in the name. The "eco" part of that name is right on the money since this nifty little device will allow you to receive up to 23% savings on heating and cooling costs (depending on your settings). The "smart" part is there not just for show either. The model works with just about any iOS and Android device, even including the Apple Watch. Furthermore, with the help of Amazon Echo, you will be able to just ask Alexa to adjust the temperature settings without standing up from your chair or using your smart device.

Of course, these compatibilities are all well and good, but they wouldn't be enough to justify the said "smart" part. On that note, we would like to point out the set of alerts and reminders. The manufacturers made sure to incorporate those in order to offer their customers a certain peace of mind. Simply put, the WiFi thermostat senses when something doesn't work at all or doesn't work according to your programming and sends a convenient alert to your smart device. There's also the vacation mode that the device automatically adjusts to whenever you leave the house, a rather sophisticated solution that allows you to save a considerable amount of money in the long run. Finally, in terms of HVAC compatibility, the model works with most residential heating and cooling systems.

All in all, the Ecobee3 lite Smart Thermostat is all about saving money and offering convenient ways to control the temperature around the house. Plus, the installation process is extremely easy since all you need for it is included in the package.

Lux GEO

Flexibility and Control

What makes this unit stand out is the unusual design that makes it look like a regular thermometer. Unlike a regular thermometer, though, the device hides a lot of useful features beneath its housing. So, let’s take a closer look at what makes it so unique, shall we?

Right off the bat, the device features a monochrome yet highly detailed LCD screen that will conveniently show all the data you may possibly need when assessing the overall climate inside your house. This includes the current temperature (both indoor and outdoor), date, and time of day, along with the current status of the ventilation, heating and air filtering systems.

Moving on, this smart thermostat has a number of convenient features that will help you in creating and maintaining a constant ambient climate inside of your house or apartment. Let’s start off with the controls. There are two ways you can go with this model, either by installing the Lux mobile app that is available for Android and iOS devices or by using the interface of the thermostat itself. Easily programmable with just a dial and two buttons you can set up a schedule for temperature change throughout the week. Although it is quite easy to do, it will be just a bit too time consuming with the manual controls, and thus, we strongly recommend using the mobile app instead.

The device can be installed either vertically or horizontally and depending on which one you choose the LCD screen will adapt and turn accordingly. Furthermore, this model can be powered in three different ways: by micro USB, c-wire or by 2 regular AA batteries. This feature alone makes it a good choice in terms of reliability, especially in situations when power outages are common or expected.

To wrap things up, the GEO thermostat from Lux is definitely one of the go-to picks when it comes down to versatility and sheer effectiveness. On top of that, this model is budget-friendly as well, so in case you always wanted to improve your existing HVAC system and create a truly smart home it is time to stop hesitating.

Hive US9000891

An Affordable Controller

By being one of the most accessible models on the market this smart thermostat from Hive beats almost any other model in the medium price range out of the competition. When it comes to functionality and the number of options it provides you with there are just a few alternatives to the Hive hub and their thermostats.

First of all, the thermostat can be connected to the existing HVAC systems such as boilers, climate controls (both heating and cooling), as well as ventilation and air pressure controllers. Speaking of the latter, the device wouldn’t be able to interact with them and is only capable of monitoring their current status. With that in mind, the large LCD screen of this model will show you the temperature as well as the status of the mentioned systems.

The only issue that is worth noting is the programming of the device, which is quite complicated to begin with. First, the unlinking process is quite tiresome and may take a while to complete. Secondly, you will have to manually delete every day from the schedule before you will be able to add any new data, which is a bummer, since if you have a slow internet connection the process may take up to 10-15 minutes to complete.

Other than that inconvenient feature, the device is quite easy to use and control. You can easily manage all the connected systems via a mobile application that is available for download for both iOS and Android-powered devices.

Review of Hive US9000891 Smart Thermostat

Control the Climate How You Want

By using the mobile app you can set up the current temperature and see the status of all the HVAC elements of your house in real-time. What is more, you can also link the thermostat to the Alexa products in order to manage the climate. After the Alexa compatible device is connected and linked to the climate control unit all you need to do in order to change the temperature is say the command out loud.

In addition to an already impressive list of features, you can add more than one thermostat of the same model to one hub. This will be convenient for users that need more than one temperature setting for different rooms at the same time. For example, you can disable heating in the bedrooms when you are at work and turn it on in the living room and kitchen so the house will utilize the energy more efficiently.

In the end, this model from Hive is perhaps the best smart thermostat available on the market when it comes to technologically advanced climate controllers. Moreover, thanks to its affordable price, it makes smart technology available for every household.

What Is a Smart Thermostat?

A smart home is becoming a commodity that is affordable for many of us these days. Remote control over household appliances and systems allows cutting down utility expenses, to say nothing about convenience.

As we all look for a solution to pay less for electricity during colder months it may be hard to pick a product that will make the indoor climate comfortable. The best solution to get your heating system under control and use it in the most efficient way is a smart thermostat. Not only is it a great addition to any house in terms of convenience, but it will also help you to save up on the electricity bills. Some people who use a regular thermostat or don’t have any at all, tend to turn the heating systems on and off manually to keep an eye on energy consumption. However, the chances are - you will likely forget to turn it off and waste energy anyway.

A modern thermostat, on the other hand, gives you the power to control the temperature remotely via your smartphone or another mobile device. You can also choose the most comfortable individual setting depending on the temperature outside and your personal needs. What is more, with such advanced devices, you can make up your own heating schedules for weeks and days ahead individually.

So, if you want your house to always stay cozy without extra hassle, choose one of these. And if you want to enjoy the ambient warmth, no matter where you are, we recommend taking a closer look at the top personal heaters as well as at space heaters that will improve the climate in rooms without central heating.

What Features to Compare

Finding a good thermostat that will suit your home or apartment might be a real challenge. However, it is not nearly as hard as it may seem at first glance. There are many different aspects that make some models suitable for your climate control systems, while others don’t. Thus, it is important to consider all features that may boost or, in some cases, interfere with the ambient temperature of your house. Before making a final decision, we encourage you to take a look at the core features that make each thermostat product unique to a certain extent.

Control Type

First things first, the controls are, perhaps, one of the fundamental aspects of any thermostat. Without them - you wouldn’t be able to set the temperature level that these climate control units are keeping at a constant level. Fortunately enough, the majority of modern smart models feature both manual and digital controls. If one of the two systems fails you can always rely on another in order to keep yourself cool or warm, depending on the time of the season. The convenience of modern devices lies in details since today you can access the control panel of the thermostat using your mobile device. Likewise, you can use a touchscreen or dial buttons just like the good old days when everything was analog (however, this is a mere necessity of emergency controls rather than the only control option available).

HVAC Compatibility

The ability of the thermostats to blend in seamlessly into your existing home climate control system is a must, especially nowadays, when multiple home systems are interconnected with each other. Some models can only be connected to boiler and heating systems, while others can also interact with humidifiers and dehumidifiers. With that in mind, it is important to assess the total number of connections that your new thermostat can handle at the same time. The HVAC systems may include electric, gas, air supply as well as air conditioning systems, hence, if you want less hassle with all of them we recommend opting for a thermostat that is capable of controlling most of them simultaneously.

Power Supply

Without electricity, a thermostat would be as useful as a regular thermometer. So, usually, the smart devices can be powered by either the home's electric system, batteries or both. While the majority of the households in the US rarely suffer from power outages it is not a bad idea to be prepared for the worst, especially in winter. If you need additional peace of mind, we recommend the models that can be powered by both outlet and batteries.

Display

It wouldn’t be a smart thermostat if it didn’t have a display that shows information about the climate indoors, would it? That’s why almost all models have at least a monochrome LCD screen. Even though LED displays are pretty beautiful to look at, it is the functionality that is important. By choosing a model with a display that will show you detailed data from relative humidity to ambient temperature inside your house you will future proof the premises for years to come.

Did you know?

How to Install and Set up a Smart Thermostat

Programmable thermostats are designed to make climate control as easy as using a TV remote control. However, installing these devices might appear finicky at first. Even more so, trying to wire the thermostat into an existing HVAC system can be a painstaking task, especially if you have little to no knowledge in the area of climate control systems. That being said, the installation process can be easy if you follow some simple instructions.

  • First and foremost, you should always check if the new thermostat model came with instructions or a user manual from the manufacturer. As simple as it may seem, this is an important part of almost any installation process, so don’t hesitate to give the manual a thorough read before trying to install the device on your own. By doing so you will avoid a lot of common mistakes such as selecting between gas or electric means of central heating.
  • Moving on, it is time to check the voltage and turn off the existing thermostat (if you have one). After that, you will need to cautiously cut the wires and disconnect the old thermostat. Note that it is important to not let the wires fall back into the wall, use duct tape if you need to secure the cables. In addition, you can label the wires so it will be easier to connect them later. In order to make the process easier, you can tape all the cables to a regular pencil so they will be in one place.
  • After the old device is out of the way, it is time to install the mounting wall plate of a new thermostat on the wall. If the new plate is bigger than an old one, use the new one as a template for drilling the screw holes. A level is a must, especially if you want your new climate controller to blend with your room design. Most thermostats come equipped with mounting screws, however, sometimes you will have to figure out the correct screw size (a 3/16” drill will suffice most of the standard sizes). Don’t forget the anchors, since they will stabilize and hold the thermostat on the wall.
  • And now it is time for the most interesting part - wiring. Hook all the disconnected wires to your new thermostat, and use notes or labels that you have already made to re-connect the cut cables. If you wish, you can copy the pre-existing wiring. If you have some empty ports and connections left, don’t worry about it, the device will work fine without them.

After everything including the back panel, wiring, and the thermostat itself has been installed and connected, you can finally update the firmware and proceed to the programming part. Even though the software solutions for each model differ, one thing always stays the same - users manual. By following the user’s manual you will find every programmable option you may need. Alternatively, you can use a mobile application to make the programming process quicker. Most of the modern thermostat applications feature a thorough tutorial on how to set up a schedule for your smart thermostat. The programmable thermostat can and will save you a lot of money on heating bills, so by using all the features in a clever way it will definitely improve your annual savings.
