BLE Relay Bluetooth

Ble Relay Bluetooth — control BLE relays and selected smart locks from your iPhone, anywhere in the world.

Built for riders and makers who need a fast, reliable way to arm a motorcycle contact, switch channels, or open a lock—without digging through complicated tools.

Relays that just work Connect popular BLE modules including A72Z / XY-MBO21F (NBH), LC Tech (A0), DSD TECH, JDY / HM-10 UART, ZL / TwoSwitch, plus prepared profiles for Tuya, Shelly, Sonoff, ESP DIY and generic GATT. Auto-detect or pick the brand manually. Set proximity from 1–10 m, calibrate on site, adjust RSSI thresholds, TX power, PIN, name, bonding and more.

Motorcycle contact, done right Turn the contact ON or OFF from the app, the widget, or Siri—while keeping the app in the background. Auto-connect when you get within ~10 m of your saved module. One-tap control on iPhone Duo’s cover display.

Smart locks ready Browse 10 major lock brands. Nuki users can unlock, lock and unlatch over the local Bridge HTTP API (LAN). Other brands are prepared for upcoming full support.
