How to Make Your Air Conditioner Smart

If you are into smart home devices and you want to buy a new air conditioner, you will probably know what to choose. But, the question is what to do if you already have an air conditioner that you have purchased before the era of smart home devices? You would probably want to control your air conditioner with your phone, set schedules for cooling and heating, enable geofencing, improve your comfort and save energy. In other words, all functionalities that are shipped in modern smart air conditioners.

One of the first questions that will come to your mind is “How Do I Make my Air Conditioner Smart”? In order to make your old air conditioner smart, you will need a separate device called “Smart AC control”, also known as “Smart Air Conditioner controller”. This device uses infrared technology and can mimic the regular remote control. On the other side, it is WIFI enabled and you can access its interface by installing a proprietary application on your phone. This application makes it possible for you to control your air conditioner remotely using your phone and also brings smartness to your old AC. This is the most efficient way to turn the old air conditioner into a smart air conditioner.

I will explain all of this little more.

What is a Smart AC Controller?

A smart AC controller is a device that uses infrared technology and is able to manage the air conditioner similar to the common remote control does. Unlike the common remote control, this smart AC controller is WIFI enabled and is enriched with almost all the features as the modern smart air conditioners. The smart AC control is usually placed near the old air conditioner, therefore it has a direct line of sight to the air conditioner.

On the other hand, the Smart AC Control is connected to your home WIFI and it exposes all its functionalities through a mobile app that you can install on your phone, which now becomes your new remote control. In simple words, the smart AC controller acts as a bridge between your old AC and your phone. The fact that it is connected to your home WIFI network, gives you the freedom to control your AC from wherever you are and utilize all of its smart functionalities.

Can I control Smart AC controller with my phone?

Yes, you can control the smart AC controller with your phone. This is because all smart AC controllers come with a proprietary mobile application that you will install on your mobile phone. On the other side, the smart AC controller is connected to your WIFI meaning that it is reachable over the Internet. Either from your home or from your workplace, you have a direct insight into the ambient conditions in your home, therefore you can manage the temperature levels, set schedules, etc. based on your preference.

Can I control Smart AC Controller with Google Home or Alexa?

Most of the Smart AC controllers available on the market are compatible with Google Assistant, which means you can integrate them with Google Home app.

But they are not only compatible with Google’s technology. At the same time, they are compatible with Amazon Alexa, which leaves you the most of the options open to choose how you will use them.

Does Smart AC Control improve energy savings?

According the US Department of EnergyOpens in a new tab., you can save an estimated 10 percent a year on heating and cooling costs by just using a programmable thermostat. And this is a conservative estimate because some of the manufacturers estimate energy savings up to 25%, which means lower energy bills.

The modern smart AC controllers have embedded temperature sensors and you can set schedules to turn the air conditioner ON or OFF if they reach the defined temperature levels. In other words, the smart AC controller acts as a programmable thermostat that you can configure based on your heating/cooling needs.

How to know if your old air conditioner is compatible with a smart AC controller?

Maybe you are tempted to convert your old air conditioner to a smart air conditioner, but the first thing you need to do before making a final decision is to see whether the potential smart AC controller will be compatible with your old air conditioner.

Some manufacturers provide simplified guides by referring to the remote control, whether it has a full state display, or whether it shows temperatures only, or it doesn’t have a display at all. Tado Smart AC Controller is an example of thisOpens in a new tab..

Some manufacturers, like Atomi Smart, claim that their Smart AC Controller is compatible with all air conditioners with remote control.

However, there are manufacturers who offer pretty detailed information in terms of compatibility, such as Sensibo. They have a dedicated web pageOpens in a new tab. where you just type your AC model and you find out right away whether it is compatible with your air conditioner or not.

  1. Thanks for the review Milan. I own two x Sensibo. They are fine except for two reasons:
    – My wife insists on using the “normal” remote causing the app getting out of sync
    – I don’t want a cord hanging down my wall (They all have it)

    I am trying to find something similar but cordless. Kind of like a remote.

    Thanks again

    1. Hi Jimmy, congrats for having Sensibo. I understand your concerns. If I were on your place I would speak with her and explain the advantages of using the phone to control the AC, at least I would configure the Google Assistant to work with Sensibo, and then just explain how to use it “Hey Google, increase the temperature”, or similar prompts. People usually stick with old methods until they are educated to use new technologies. And afterwards they recognize the benefits. And for the second concern, I would hire a handyman to drill the wall and hide the cord behind it, then fix the holes and paint it again – so only the device will be visible on the wall. I hope this will help :)
