Smart Hotel Room Control
Wired hotel gateway + control panel + room devices: stability-first room control
Built around an STM32 wired hotel gateway — Ethernet uplink, RS-485 downlink to room devices — paired with a control panel with custom UI and voice, and integrated with the hotel management system and cloud platform.
Problems to solve
- 01Hotels have heavy interference and short maintenance windows; wireless links drop out
- 02Room-control protocols and PMS differ from hotel to hotel and need per-project integration
- 03The room panel has to look good and work well; false voice wakes are unacceptable
