UniControl Remote: Universal Remote Control for Home Appliances

C/C++
To use the UniControl Remote:

Power On: Turn on the UniControl Remote by pressing the power button.
Connect to WiFi: The remote automatically connects to your home WiFi network. Ensure your WiFi credentials are saved in the remote or enter them through the mobile app.
Select Appliance: Use the touchscreen interface to navigate and select the appliance you want to control.
Control: Adjust settings, turn devices on/off, or manage operations through the touchscreen, mobile app, or by voice command.
Voice Activation: Simply speak your command, like “Turn on the lights,” to control appliances hands-free.
Mobile App: For remote access, use the UniControl mobile app, which mirrors the remote's interface and offers real-time control from anywhere in your home.
