The following steps describe a concise, safe setup for the Shelly BLU door/window contact sensor. This guide covers unboxing, connecting via Bluetooth, placement and basic testing. Do not perform any electrical work — this device is a low-voltage Bluetooth contact sensor and does not require mains wiring.

  • Unbox and inspect
    • Open the package and confirm the sensor body and magnet are present and undamaged.
    • Look for any quick-start leaflet from Shelly for product-specific details; this guide assumes Bluetooth pairing capability as indicated by the product title.
  • Prepare your smartphone or tablet
    • Install the Shelly Bluetooth or Shelly mobile app from your device's app store if available. If unsure which Shelly app to use, search for Shelly Bluetooth or consult Shelly support.
    • Enable Bluetooth in the device settings and grant any location or Bluetooth permissions the app requests (required for Bluetooth scanning on many devices).
  • Power and initial device state
    • Some wireless contact sensors ship with a factory-installed battery; the battery type and whether it is pre-fitted are not specified here. If the sensor has a removable cover, open it gently to check for a battery and follow any leaflet instructions for insertion.
    • If the sensor requires a user action to enter pairing mode, follow the manufacturer leaflet. If no leaflet is available, place the sensor close to your phone and proceed to the app; many Bluetooth sensors advertise automatically when powered.
  • Pair the sensor via Bluetooth
    • Open the Shelly app and use the device discovery or add-device function. Allow the app to scan for nearby Bluetooth devices.
    • Select the sensor from the list when it appears. The device name will usually include "Shelly" or "BLU"; exact naming is not specified here.
    • Follow the app prompts to complete pairing. The app may ask you to confirm a device ID or press a button; follow on-screen instructions in the Shelly app.
    • After pairing, check the app shows the sensor as connected and reports an initial contact state (open or closed).
  • Verify behaviour and perform a functional test
    • Bring the magnet and sensor together and observe the app state change to "closed" (or equivalent). Move the magnet away and confirm the app reports "open".
    • Repeat several times to ensure consistent reporting and confirm Bluetooth range is sufficient for your intended location.
  • Mount the sensor and magnet
    • Choose a flat mounting surface on the door and frame (or window and frame). Clean surfaces with a cloth or alcohol wipe and let dry.
    • Position the sensor body on the fixed frame and the magnet on the moving part so that when the door/window is closed the two parts are aligned and close together. Maintain a small gap; the exact maximum gap is not specified here, so keep them as near as practical without obstructing movement.
    • Fix in place using the supplied double-sided tape or screws. If using screws, use the small Phillips screwdriver. Ensure secure mounting so alignment does not shift in normal use.
  • Final checks and maintenance
    • Confirm the app still shows correct open/closed status after mounting and after several open/close cycles.
    • Check the Shelly app for available firmware updates for the sensor and apply any updates the app offers.
    • If planning to integrate with third-party systems or hubs, consult Shelly documentation; third-party integration is not specified here.
    • Replace batteries as recommended by the manufacturer; battery specifications and life are not specified in this guide.
