To turn on the air conditioner with your phone, you first need to make sure that your phone is infrared-capable. Only with this feature can your phone communicate with the air conditioner and send control commands.
Once you confirm that your phone has infrared function, you can use the remote control app that comes with your phone to operate or install a universal remote control app, such as "Smart Home" or "Remote Control Genie", etc. These apps can communicate with the air conditioner via infrared, allowing you to control the air conditioner using your mobile phone.
*And after installing the app, you need to follow the instructions of the app to set it up. Usually, you need to pair your phone with your air conditioner so that your phone can recognize and control your air conditioner.
Once the pairing is successful, you can use your phone to turn the air conditioner on or off, adjust the temperature, set the mode, and more. With the touch screen or voice assistant on your phone, you can easily control your air conditioner without leaving the comfort of your couch or bed.
Alternatively, if you don't have infrared capabilities, you can also consider purchasing an external IR emitter. This device can turn your phone into a remote control, allowing you to control infrared-capable devices such as air conditioners, TVs, etc., from your phone.
In short, using a mobile phone to turn on the air conditioner requires a certain amount of technical knowledge, but if you are familiar with the operation of the mobile phone and the use of the remote control app, you will be able to easily control your air conditioner and enjoy the convenience and comfort brought by smart home.
