6 Best Smart Air Conditioner Controller Reviews 2021

You can now control your air conditioner from the comfort of your phone, thanks to smart AC controllers. These intelligent devices give you the tools to manage the home’s temperature from wherever you are so you can walk into the most comfortable environment when you arrive home from work.

You can also adjust temperatures from your phone from the car as you leave the house in the morning.

We’ll discuss how to pick the best smart AC switch for your home shortly. However, let’s begin by rounding up some excellent options to consider if you’re in a hurry.

What’s a Smart AC Controller?

An intelligent AC controller is an electric device that turns your air conditioner unit from a basic digital control unit to a smart appliance controllable via smart home systems.

The smart AC controller connects to your existing smart home technologies and devices to upgrade your AC and other appliances, eliminating the need to purchase a new smart air conditioner. Typically, it works with any AC unit that uses Infrared (IR) signals.

Most smart controllers support a wide range of air conditioners, including window units, ductless mini splits, portable models, and through-the-wall models. However, a few are designed specifically for selected AC types. For instance, the device may only support ductless mini splits or ductless units and window ACs.

Traditionally, smart AC controllers also target specific AC models, especially from the major manufacturers. It’s crucial that you keep this in mind. You want to choose a unit that supports your AC model.

How Does a Smart AC Controller Work?

It’s a two-part process. First, the smart controller needs to connect to your air conditioner. It does this by mimicking your air conditioner’s remote. Secondly, it needs to connect to the app on your smartphone. It does so by leveraging your home’s Wi-Fi network.

Once the two processes are completed, the smart controller gains complete control over the connected air conditioner. Remember that you can connect it to one AC or a group of air conditioners. Some even connect to fans and dehumidifiers.

To change your AC settings, all you need to do is access your smartphone, find the relevant app, and make the desired changes. If the smart controller connects to other home comfort appliances, such as humidifiers and fans, you’d be able to control nearly every aspect of your indoor climate from the convenience of your smartphone.

Smart AC Controllers vs. IR Repeaters; Which one is Better?

Smart AC controllers are better. Infrared repeaters give you a degree of control over your AC too. Indeed, you can change temperature settings with ease using the average IR repeater. However, the smart AC controller is superior for the following reasons;

  • Greater climate control: The smart AC controller gives you greater control over temperature, modes, and fan speeds. To control all these indoor climate elements using an IR repeater, you’d need a custom program for each function.
  • More user-friendly: All smart AC controllers come with a smartphone app that makes it extremely easy to adjust temperatures and make necessary changes for ultimate indoor comfort. IR repeaters aren’t as friendly.
  • Built-in humidistat and thermostat: Above all, smart AC controllers typically feature a built-in thermostat and humidistat for greater temperature accuracy in real-time. This enhances precision in climate control.

Does that Smart AC Switch Sync with the AC Remote?

It’s a question many people using the smart AC controller for the first time ask – can I sync the controller with the remote?

The short answer is – no. The smart AC controller only allows for one-way communication to the air conditioner. It sends commands to the AC but cannot take instructions or receive information from the same AC.

So, you can change cooling temperatures from the smart controller, but if someone adjusts the settings at the AC itself, you wouldn’t know. Also, the typical smart AC controller wouldn’t detect if you change the AC settings using the IR remote.

Ditching manual controls completely can help eliminate this problem to a degree. It clears the communication path between the controller and the AC.

What Else Do I Need to Know?

A few advanced smart AC controllers can detect and keep track of infrared signals from your remote controller, thus know what your AC is doing at any given time.

Cielo and Sensibo AC controllers are particularly good at IR remote tracking. However, if you’d like a smart AC controller that gets as close as possible to providing a synced performance where everything is connected, you should consider the advanced controllers from these two companies.

Smart Air Conditioner FAQs

Can I control my AC remotely? Yes, you can control your AC remotely using a smart AC controller. These controllers come with an app that allows you to adjust temperature settings, change modes, etc., from your smartphone’s convenience.

Can I control my AC with my iPhone? Yes, you can control your AC with your phone using a smart AC controller application. The best part is that most smart AC controller manufacturers have apps for Android and Apple devices.

Do I need an AC controller for every AC unit? Yes, in most cases, you need an AC controller for every air conditioner in your home. The only exception is when using smart AC controllers that can group AC units. These controllers allow you to control more than one AC unit from the same app.

What are the benefits of a smart AC controller? There are many benefits. Smart AC controllers help you save energy. You can save up to 25% of energy costs by investing in one. Secondly, they increase user convenience. You can control the AC from your phone. Above all, they are also a great way to transform into a smart-home life.
