Using an old air conditioner (AC) as a smart plug without any wiring or installation is not possible in the traditional sense. A smart plug is a device that you plug into a standard electrical outlet, and it allows you to control the power supply to whatever is connected to it remotely through a smartphone app or voice commands if it supports smart home platforms like Amazon Alexa or Google Assistant.
An old air conditioner typically requires a direct electrical connection to a power source, and it cannot be controlled solely through a smart plug because the AC needs to be powered on and off to function. The smart plug can only control the power supply to the plug itself, not the AC unit that is hardwired.
If you want to make your air conditioner "smart" and be able to control it remotely, you have a few options:
Smart AC Controller: There are smart AC controllers available in the market that can be installed on the AC unit itself. These devices allow you to control the AC remotely via a smartphone app or smart home platform.
Smart Thermostat: If your AC system is connected to a thermostat, you can replace your old thermostat with a smart thermostat that offers remote control features and compatibility with smart home platforms.
Smart Plugs for Other Devices: While you can't directly control the AC with a smart plug, you can use smart plugs for other devices or appliances that are plug-and-play, such as lamps, fans, or other small electronics.
Remember that for any smart device integration or installation, it's important to follow the manufacturer's instructions and safety guidelines to avoid any electrical issues or damage to the devices involved. If you're not confident in handling electrical connections or installations, it's best to consult a licensed electrician or HVAC professional for assistance.
