The ESP microcontroller is responsible for controlling the Electra Minimax AC and its dampers.
Each ESP device is uniquely identified by its BLE MAC address, which allows the system to precisely locate and control individual devices in a multi-device setup.
This ensures that commands are sent to the correct ESP device, enabling seamless operation across multiple units.

Each ESP functions as a BLE peripheral, meaning it advertises its presence and waits for commands from a central controller.
The central controller, referred to as the BLE master, acts as the remote control for all connected ESP peripherals.
The BLE master sends commands to the ESP devices, which then translate these commands into IR signals to control the AC and its dampers. This architecture allows for centralized control of multiple ESP devices, providing a scalable and efficient solution for managing multiple AC units and dampers.
