Energy usage has become a more relatable phrase to most homeowners over the years. And whenever it comes to controlling power usage around the home, smart thermostats that don’t require a C wire are often the best bet. They are incredibly convenient, making it possible for you to automate your home’s cooling and heating system.
Regardless of where you are at any given time, you can control your smart thermostat by simply connecting it to a Wi-Fi connection. This is possible even when you are not at home. Apart from helping you beat down your energy bill to a considerable extent, you are also able to schedule the proper temperature for your home. So, if you are looking for the best means to get started on building a smart home, you can begin by opting for smart thermostats.
When seeking the best smart thermostats for your home, there are certain things you need to consider. Top of these factors that should be considered is whether the device requires a C wire or not.
What Exactly is a C Wire?
Commonly referred to as C wire, this term is a short form of ‘common wire’. It is a cable that provides a continuous flow of 24 volts AC (24 VAC) to power a smart thermostat. Although this is similar to the R wire, it is quite different. Unlike the R wire, this cable provides constant and uninterrupted power. This is what makes it primarily suitable for smart thermostats.
This does not rule out the fact that using a smart thermostat without a C wire is possible. Since C wire isn’t often included in most home wiring, running thermostats without C wire is possible. Thanks to technology, many smart thermostats that do not need C wire to get powered are now available.
Things to Consider Before Buying a Smart Thermostat
It is essential that you consider some factors before settling for any smart thermostat, especially when you are purchasing for the first time. By getting yourself familiar with the different qualities to look out for, you will avoid making mistakes that will save you some repair costs in the future. Not only that, the right smart thermostats will increase your chances of controlling activities around your home.
Although most smart thermostats come at cost-friendly rates, you should opt for an internet-compatible device. With the aid of technological advancements and improvements, a large number of these devices are equipped with Wi-Fi connections. As a result, you are able to connect them to your home internet and network. This enables you to control the device remotely using a free mobile application via your smartphone or tablet.
To complement the ease of these smart thermostats, some of them can be controlled via a web browser. Thus, if using a smartphone or tablet isn’t a suitable option for you, you can settle for a Google browser to help you out.
Heating and Cooling Controls
It goes without saying that you want a device that will enable you to decrease and increase your home’s temperature. The basic controls attached to most smart thermostats will allow you to do the following.
- Make a seven-day cooling and heating schedule
- Turn the system on and off
- Adjust a previous schedule due to emergency
- Keep a tab on daily activities, including your goings and comings.
You have more benefits to enjoy if you settle for some cutting-edge thermostat models such as the Nest Learning Thermostat. Being one of the most effective smart thermostats that don’t require a C wire, this device keeps a tab on your heating and cooling trends over time. This way, it is able to determine your preferred temperature at any given time. Interestingly, it can create a cooling and heating schedule based on your presence or absence from the home.
This is a modern tech attached to most smart thermostats. If your device supports this tech, it will be able to lower your home’s temperature whenever you are out and kick back whenever you come in. The Nest Thermostat remains a prime example of a smart thermostat with this technology.
With the aid of this tech, your smart thermostat can determine whether you are in any part of your house or not, thereby controlling the temperature around you. This is possible through your mobile phone’s location services.
All you need to do is mark your preferred Home and Away temperatures and ensure that you have your phone with you each time you’re in or out of your house. This way, the thermostat will be triggered each time you step into or step out of your home.
Humidity sensors are another perk you should look out for in a smart thermostat. You should find them readily attached to most of the latest smart thermostats. These tools usually trigger an alert when a low or high humidity level is detected. That’s not all. Some thermostats have the capacity to show your local weather forecast.
A good example of such a device is the Ecobee Smart Thermostat. It has a remote room sensor and voice control that ensures that temperature remains uniform in every part of your home, especially in areas that are at a distance from the thermostat.
Display and 21st-century Design
Whichever device you will be considering the best for your home must be feature-rich. Display is one thing you can’t leave out of the features to look out for before buying smart thermostats that don’t require a C wire. Programing and configuring your thermostat come in handy once it has a colorful touch display. This display gives the thermostat a touch of style, allowing you to read even from a distance.
By simply tapping the screen of most typical thermostats, the menu settings, temperature, and current time come up. However, advanced and smart thermostats come with motion sensors that will get the display activated once you step into the room.
Apart from this, 21st-century designs such as Google Assistant voice commands, Apple Siri, and Amazon Alexia are included in most smart thermostats.
These designs allow you to use your voice to determine the current temperature and change temperature settings. Just like a smart speaker, most smart thermostats have readily attached Alexia voice control that enables you to:
- Change temperature settings
- Determine the weather forecast
- Get the latest sports scores and news
- Play music, and do a lot more with your voice.
