How To Buy the Best Battery-Powered Smart Thermostat

Since the market is never short of these smart home devices, you will need to consider a few features to source the latest smart thermostats for your residential space. And these features include the following:

The User Interface

Smart thermostats with a touchscreen interface are easier to control. They boast a one-touch touchscreen display for adjusting the temperature with a single touch. As such, they offer efficient temperature control and comfort customization. But this will require you to be closer to your unit. Since a touchscreen interface guarantees ease of control, you can consider buying smart thermostats with touchscreen displays.

Remote Access

The idea for installing a smart thermostat in your home is to control your home temperature from wherever you are. Remote access comes in handy if you want to customize your home temperature when you’re many miles away. But for this to be possible, your smart thermostat needs to connect to the Wi-Fi using its built-in Wi-Fi.

Additionally, it could also connect to a smart hub for remote control. Therefore, consider a smart thermostat that grants you remote access. But since those requiring a smart hub subject you to spending a few extra bucks, you could buy those with built-in Wi-Fi. But if you’re looking to control other smart home devices remotely, invest in a smart hub.

Geofencing

This is a smart feature you want in a smart thermostat. It uses the smart thermostat’s mobile app and your phone’s GPS service to know where you are. As a result, your smart thermostat will always know when to power down the HVAC system and when to power it up again.

And in the long run, your smart thermostat will save electric power, slashing a few bucks off your electricity bill in the process. Since this is an energy-saving feature, ensure your preferred smart thermostat features it.

Auto Home and Away

Smart thermostats use different techniques to know if you’re at home or away. And the Auto Home and Away is one of the features they use to know if you’re present or absent. If such a smart thermostat detects that you’re absent, it turns down the heat to save energy. It will only turn up the heat if you’re within your premises. Since this feature also saves you energy, you should consider a smart thermostat featuring this energy-saving smart feature.

Room Sensors

Room sensors assist your smart thermostat in customizing the temperature for each room. You only need to place sensors in rooms whose temperature you’d love to customize. As such, room sensors are an excellent addition to your smart thermostat. But some smart thermostat models don’t come with these useful accessories. And you want to ensure your smart thermostat includes them in the package.

Also, room sensors detect unoccupied rooms. And your smart thermostat will then shut down the temperature regulation of the unoccupied room. As a result, your HVAC system will use less electric power since it will only customize the temperature of the occupied rooms. Therefore, consider smart thermostats that include room sensors.

Compatibility with Voice Controls

If you need hands-free control of your smart thermostat, pair it with a compatible voice control device such as Alexa and Google Assistant. But as you might expect, your smart thermostat might be incompatible with some voice control devices. So, you want to buy a model that works with your preferred voice control device.

Once you have paired your smart thermostat with a voice control device of your choice, you can be sure to control the temperature by voice. For example, you could ask Alexa to turn up or turn down the heat, and your HVAC system will follow your voice command. Therefore, voice controls provide convenience, and it is something to look for when buying smart thermostats.

Electrical Power Needs

Some smart thermostats use battery power to function, with most models relying on electric power from a C-wire. But since we’re talking about battery power in this case, you want to carefully consider the type of battery your smart thermostat will use.

First, you want powerful batteries. Besides, powerful batteries provide steady and reliable power to your smart thermostat for an extended period. Second, batteries with sufficient power will not need frequent charging. So, you have reasons for selecting powerful batteries. But to know a powerful battery, check its milliamp Hour (mAh) rating.

The higher the rating, the more powerful the batteries are. So, look for a higher mAh rating. Also, consider opting for rechargeable batteries. But non-rechargeable batteries also function well if you don’t mind replacing them once they run out of charge. You could also select a smart thermostat that requires a C wire as an alternative power source. This means you could still power your smart thermostat if your batteries run out.

Integration with Smart Home Devices

You might want to control your smart thermostat remotely alongside other smart home devices. If this is the case, you want to ensure your smart home devices are compatible with other smart home devices. But this will require a smart hub. What’s more, you could link a smart thermostat with a smoke detector, and it will stop the HVAC fan if there is a smoke buildup in your residential space.

Also, a smart thermostat that seamlessly integrates with other smart home devices allows you to link it with occupancy sensors. And when no one is in a room, the smart thermostat can turn down the heat to save energy. Therefore, ensure you buy a model that integrates with other smart home devices for efficient temperature control.

FAQs

How many volts do smart thermostats need to function fully?

Smart thermostats that use battery power to function require a certain voltage to function fully. Usually, they require 3.6 volts to function, and a dip below this voltage threshold could mean your smart thermostat will forfeit some functions.

For example, the Nest Learning thermostat requires 3.6V for all of its features to function. And if the voltage falls below 3.6V, it will disable some features such as Savings Finder and weather forecast to conserve energy.

Do battery-powered smart thermostats also require power from a C-wire?

Some battery-powered smart thermostats also use power from a C-wire to supplement the battery power if their batteries run out. A good example of such a smart thermostat is the Emerson Sensi Wi-Fi Smart Thermostat. So, battery-powered smart thermostats could also use power from a C-wire to function.

Can I control my battery-powered smart thermostat by voice?

Yes, you could control your smart thermostat by voice, but after you have paired it with a voice assistant. Fortunately, these devices connect to your Wi-Fi network, allowing you to control them by voice using smart speakers connected to the same Wi-Fi network. But they might be incompatible with some voice assistants. So, you want to make sure you’re pairing them with only compatible voice control devices.

What does Geofencing work to achieve in a smart thermostat?

Geofencing is a smart feature that uses the smart thermostat’s app and your phone’s GPS to know where you are. Then it instructs the smart thermostat to turn down the heat if you’re far from home. And this action saves electricity bills in the long run. Therefore, you want to ensure you’re buying smart thermostats with this feature.

Wrap Up

Battery-powered smart thermostats can help you control your home temperature excellently without relying on some other electric power source. What’s more, they connect to your Wi-Fi network to grant you remote control over them. Also, their Wi-Fi connectivity makes it possible to control them by voice using your preferred voice control device.

They have everything you need to control your home’s comfort while also saving energy. Therefore, they are ideal for any smart home. But the market has plenty of battery-powered smart thermostats, and you can be sure to find substandard models.
