  "description_en": "Hisense AEH-W41H1 local control replaces the air conditioner's cloud-connected Wi-Fi module with ESPHome firmware for an ESP32 board or the stock RTL8710C module. The implementation speaks the A/C's RS-485 bus and exposes climate controls and diagnostics to Home Assistant. Protocol notes describe the frame envelope, checksum, bus roles, and command/status behavior derived from device observation.",
