In this article, I provide a side by side comparison of Sensibo Sky vs Ceilo Breeze Plus vs Ambi vs Tado. Which smart ac controller and app is best? Let’s find out.Ah yes. The Dog Days of Summer.
We are really in the thick of it now. With last week’s heatwave, August just starting to heat up, and even more oppressive heat in the forecast for many parts of the U.S., all I can say is…it’s hot!
And that has me thinking about my AC – and last month’s electric bill 😢. AND wouldn’t it be great if I could save some money somehow, some way.
I don’t have central AC so a smart thermostat is out. So, what is a sweaty frugal boy to do?
The short answer is: there’s an app for that! In fact, there are four really good ones that will let you control both window and portable AC units. They are: Sensibo Sky, Ceilo Breez Plus, Ambi Climate 2, and Tado.
They aren’t free and don’t come cheap, but with the savings you can get on your electric bill, they could more than pay for themselves in a couple of seasons.
But which product is best?
With its user-friendly app, support for iOS and Android devices, simple set up, robust smart assistant support, plus intelligent climate control and support for IFTTT, Sensibo Sky is my top choice for the best smart AC controller and app. The Ambi 2 is a solid runner up, though it requires an existing AC remote with an LCD screen.
I will take a closer look at features and compare the products side by side in this post. This way, you can choose the best smart AC remote for your unit.
In fact, let’s start with that.

Sensibo Sky (International)
Sensibo Sky from Sensibo also supports window A/Cs, ductless min splits, portable A/C units with an existing remote control. Like Cielo, you can control your AC from anywhere using your smartphone: iOS, Android, Web app.
The “coolest” feature of this controller is probably its GeoFencing capability. This feature can be used to base operation on proximity to your home. On your way home from work about a mile away? No problem. The GeoFencing feature can be used to automatically fire up your AC based on the distance from your house. Forget to turn the A/C off before leaving your apartment? Sensibo has you covered as it can be set to automatically turn off after the last person leaves home. Cool.
You can also control your AC unit using your voice with your choice of Amazon Echo, Google Home, and even Apple Siri.
Video Review: Sensibo Sky
Here is a nice video review of the Sky from the Gadget Whisperer. Great tee shirt, man!
The company claims that Sensibo can help you save up to 40% on energy costs. Many customers who own this product swear by it.

Cielo Breez Plus
The Cielo Breez Plus from Cielo will let you control any standalone AC, including window, portable and mini-split units. The only requirement is that they either have an existing remote control or one will allow for infrared (IR) control. Oh, and it makes its initial connection through your wifi router so you will need to have existing wifi for setup.
Video Review: Cielo Breez Plus
The company has a nice overview video and covers the general installation process here:
What is great about the Cielo Breez is its flexibility in the ways you can control your AC. These include your iOS or Android device, Amazon Alexa, and Google Home.
Comes with all required accessories including the wall plate and even a free table stand if you prefer to place it on a desk or table. It helps you create zones for efficient heating or cooling.
- Set up weekly schedules as per your lifestyle
- Saves you up to 25% on your AC’s energy bills
- The app displays a timeline of air conditioning actions.
- Able to control your connected AC even without Wi-Fi [after set up is complete].
- On-device controls for local control
- Can set triggers based on temperature or humidity
- Can power up Cielo Breez Plus using 24V OR 12V hard wiring OR through 5V adapter (included in the box).
- Dedicated support team available Monday-Friday 9 am-9 pm EST
- Requires an existing AC remote
Where To Buy
👉Check the latest price and read a nice colorful brochure on Amazon’s product page.
Out of the gate, let me start by saying if you have an LCD screen remote for your existing AC, then I like this controller from Ambi Climate the best. If you don’t have one, go with Sensibo Sky.
Probably the most unique feature of the Ambi Climate Controller and app is that it learns based on your feedback. A feedback screen on the app lets you choose between Too Warm, Too Cool, Just Right, etc., so it will learn your preferences over time.
Video Review: Ambi Climate 2
Julian Ambi’s Founder has a nice demo that he did for Kickstarter out on YouTube. I’ll include it below:
Like the other controllers here, Ambi also works with Alexa and Google Home. If you have a preference for Apple’s Siri voice assistant (I prefer Alexa), then the company has you covered there too.
The controller also supports IFTTT & Geolocation services.
- Works with Alexa, Siri and Google Home
- Integrates with IFTTT
- Works with both iOS and Android devices
- Compatible with most brands of AC
- 2-year manufacturer warranty is longer than other products here
- Requires an existing LCD screen AC remote in order to work; it will not work with traditional AC remotes.
Where To Buy
Like the other products here, the Tado Smart AC controller was designed to make your dumb AC smart, and it does it using a controller and app for your smartphone or tablet. It also requires that your AC unit has an existing remote [or at least the ability to be controlled using an IR signal].
The controller itself has a sleek design with a handy display that shows you the current room temperature and a status indicator.
As Digital Trends points out in their video review, the app is where the magic really happens. In manual mode, you can control the AC and its temperature and control how and when the unit kicks into the automated mode. Smart features include the ability to set and control schedules up to a week ahead.
Video Review: Tado Smart Air Conditioner Control
Here is a nice overview from the company’s founder and CEO.
The app also has an advanced Geolocation based control. Other members of your family can also download the app and use this feature so that the AC can be set to power on when someone is getting close to home. Similarly, the AC can be set to automatically turn off when the last person leaves the house.
- Tracks temperature and humidity over time
- App control is excellent, easy to use and simpler than the other models here
- Geolocation lets you set it and forget it to enhance your ongoing comfort
- Must have existing AC remote
- A few customers have complained about setup issues and compatibility with existing IR ACs
- Micro USB cable somewhat difficult to install in the bottom of the unit
- Need a direct line of sight between Tado and AC in order for it to work
