Sensibo Sky Review

Having the perfect temperature at home in very cold or hot weather becomes very important. While heating and cooling systems help attain a comfortable home, they are also very energy-consuming.

According to some sources, the average consumer’s electricity bill is from their heating and cooling systems.

This is where smart thermostats come in. They not only help you adjust the temperate on your smart devices, but are also energy-saving. Most come with energy-star certification as well. Although there are a few factors to be considered, that will be discussed shortly.

What makes these thermostats smart is their support for other smart devices such as your smartphone, tablet, PC, and smart assistants. Most smart thermostats are supported by the big three: Amazon Alexa, Google Home System, and Apple HomeKit.

Others such as Samsung SmartThings or IFTTT are not found as frequently. Also, some smart thermostats come with sensors that allow the thermostat to automatically make adjustments to the thermostat.

Additionally, a few smart thermostats also come with learning capabilities that provide ease of use to the user. However, not all smart thermostats offer the same functions and features.

Some are compatible with specific types of HVAC and smart home systems. Moreover, some are made for easier scheduling, while others are made for more advanced features.

Similarly, the prices also vary some are budget-friendly, while others are slightly more high-end. Thus, at the end of the day, it depends on the kind of requirements, budget, HVAC system, and smart home system that you have.

While I was replacing mine, I got one with the c-wire and my previous one did not have it. Thus, I had to get the wiring redone for the thermostat to work with my HVAC system.

Sensibo Sky

A smart thermostat that caught my eye during this process was the Sensibo Sky. This review will be useful if you wish to know if it is the one you want.

Who Should Buy Smart Thermostats?

If you are someone who wishes to make their home smart, then a thermostat is a good start. They provide ease by giving you remote access to the thermostat. People who travel a lot are a good fit for smart thermostats.

They can make sure that the house is at the optimal temperature before coming home, as the smartphone app works no matter where you are. Handicapped people are also well suited to the smart thermostat as they can simply give their voice assistant a command to adjust the temperature.

Not only that but people who like multitasking can now do so without needing to leave what they’re doing. They can simply continue their tasks and give commands to the thermostat using their voice assistant.

Smart thermostats are generally good for people who have a wifi connection. As long as you have that, a smart thermostat will work for you. If you have a c-wire connection in addition to that then you should invest in a smart thermostat. This will save you the hassle of getting a new connection as most smart thermostats come with the c-wire.

Anyone looking to reduce his or her energy costs should invest in a smart thermostat. They help save about 23% annually on average.

Factors to Consider Before Buying Smart Thermostats:


If your smart thermostat works without batteries, then there’s a high chance it will come with a c-wire. C-wires ensure that the thermostat is connected to the wifi without interruption.

If it requires a c-wire but you don’t use it then there is a high chance your HVAC system will damage. However, not all thermostats require a c-wire, as some come with an adapter so you don’t need a new connection.

Ease of Installation

Youtube has a vast number of installation videos, so installing the thermostat most times is a breeze. Not only are there videos so readily available but the thermostats also come with very detailed user guides. Smart thermostats are easy to install unless you have a very complex HVAC system that requires professional configuration.


This feature is available on many basic thermostats, but that does not guarantee that all of them have it. Geofencing detects whether the GPS signals of your phone are within a certain range.

If they aren’t then the thermostat automatically makes the temperature more optimal in a way that helps save on energy costs.

HVAC System

The type of HVAC system you have determines whether your smart thermostat is compatible with it. Most smart thermostats are compatible with low-voltage systems, but some have support for line-voltage or more complex systems.

Therefore, before you purchase a thermostat you must make sure your thermostat is compatible with the system type.

Smart Home Integration

Smart home systems allow you to give voice commands to the thermostat. Although you need to make sure that the thermostat is compatible with the system before purchasing it.

Amazon Echo, Google Home Assistant, and Apple HomeKit are the three big names that most smart thermostats support. However, each thermostat has its unique capabilities so there is no guarantee that your thermostat will support the three.

Sensibo Sky Smart Thermostat and its Alternatives

The Sensibo Sky is a smart air-controller that is reasonable, allows for scheduling, and has geofencing capabilities. You can now control your air conditioner with a simple device that will provide ease of accessibility to you.

It helps you connect your old AC to your smartphone, so you can change the temperature even if you are not home.

The temperature and humidity are monitored on the phone app, which sets this thermostat apart. The 7-day scheduling, voice control through Amazon Alexa and Google Home assistant, and geofencing are its key features.

It has an infrared sensor and another S-shaped blue indicator light that works when the thermostat is in pairing mode.

Moreover, to make wall mounting easier, it has a peel off-sticker glue at the back for easy mounting. The Sensibo Sky works with any AC unit that uses a remote. This includes mini-splits, window units, central AC, and portable units.

However, it is not compatible with Apple HomeKit or IFTTT, so if you have these smart home systems then the Sensibo Sky is not ideal for you.

Alternatively, the Emerson Sensi Thermostat is not only cheaper than the Sensibo Sky but is known for its compatibility with a wide range of smart home systems. These include Apple HomeKit, Wink, and Samsung SmartThings in addition to Amazon Alexa and Google Home. However, it lacks the geofencing capabilities that the Sensibo Sky does.

The Ecobee 3 Lite is another alternative In the same price range as the Sensibo sky. It has advanced control features that interact with the local weather schedule.

Its smart sensor compatibility also sets it apart and helps save energy costs as compared to the Sensibo Sky. Moreover, it is compatible with far greater smart home systems such as the Emerson Sensi thermostat.

Honeywell Home T5Honeywell Home T5

Last but not least, the Honeywell Home T5 falls in the same price range as the Sensibo Sky. It offers much of the same features as the Sensibo sky but its adaptive recovery feature makes it stand out. Apart from that, it is energy-star certified so you will be saving up on your energy costs.

Features of The Sensibo Sky Smart Thermostat

1. Design and Installation

The device comes in plain black or white and black options and can easily fit into the palm of your hands. It has a modern, matte look with a glossy top that fits into any home’s aesthetic. However, the display does not have any controls but it needs to be mounted somewhere in front of the AC.

2. Installation

The installation is even simpler, all you need to do is connect to the power through its USB cable. Alternatively, you can connect it to a battery pack as well. Downloading the Sensibo app is a breeze as you can simply scan the code from your smartphone.

3. Climate React

This feature uses the changes in temperatures and humidity and intelligently adjusts the temperature accordingly. For instance, if the temperature drops below a certain level, then the unit turns on itself.

Although it only provides one option, it is a useful feature regardless as it helps save energy. This feature works along with geofencing that automatically knows when you aren’t home, with the help of the GPS signals.

4. Compatibility with Smart Home Devices

Sensibo is compatible with Alexa and Google Home and you can give it voice commands once connected. It will not work if the unit is not powered on. While Sensibo can connect to other smart systems like IFTTT, but the usability is quite limited.

4. Sensibo App

The Sensibo App is available on both Android and iOS smartphones. It is very easy to use and provides additional information such as the temperature of the room you are in. Furthermore, if you tap on a room you can see the fan strength, along with the temperature settings. Thus, the interface allows you complete access to your thermostat at any time and place.

What Users Think of The Sensibo Sky Smart Thermostat

My research on the Sensibo Sky showed that users thought the thermostat offered good value for the price that it is for. The setup hardly takes a few minutes, which many customers like along with the accessibility of the app.

Also, many people liked that they could check and control the humidity and temperature from anywhere in the world. Many like the geofencing feature as it helps them save on energy costs without any involvement from them.

Thus people appreciate the Sensibo Sky for its price, usability, installation, and simplicity. Its smart home capability also helps users in their everyday lives.

Final Thoughts on The Sensibo Sky Smart Thermostat

Overall, the Sensibo Sky is a basic, easy-to-use, programmable air controller whose smart features make it worth the buy. It is not a high-end thermostat as the only smart thing is its ability to pair with other smart devices.

However, it is still a good thermostat to go for if you have Amazon Alexa and Google Home. Similarly, if you don’t have these two then you should look for an alternative that is compatible with your smart home system.

The Sensibo Sky Smart Thermostat helps reduce energy costs, has geofencing and climate react features that make it a good investment. Especially considering how it does not require other installation prerequisites like having a c-wire.

However, if you need advanced features or one that supports other smart assistants then you should consider other alternatives mentioned above.
