# ESPHome ↔ L&S Emotion Control: reconstructing a smart-light radio client

> An ESPHome component recreates L&S Emotion Control remote commands so an ESP32 with a CC2500 radio can control furniture lights and reflect physical remote presses in Home Assistant. Its documented radio configuration uses MSK at 2436.2 MHz, a sync word, and 14-byte payloads carrying the remote ID, command, and value.
