EWD22S LoRa Remote Control Switch

EWD22S LoRa Remote Control Switch

The EWD22S series is a high-performance LoRa-based long-range remote control switch developed by EBYTE. It utilizes advanced LoRa spread spectrum technology in the 410–493 MHz band with frequency hopping for excellent anti-interference and long-distance communication (up to 3.5 km in open areas with certain models). The device features two-way communication with real-time status feedback to the handheld remote, wall penetration, power isolation, zero-crossing detection, and optional power-failure memory. It supports multiple remotes per switch, manual override, and is ideal for applications such as agricultural irrigation, outdoor lighting, industrial equipment, home automation, and remote appliance control. Paired with the EWD22S-YK02 series interactive feedback remote control.
