ZenDoor+ Installation-Guide

Product overview and configuration.

Written By Support Team

1. Overview

ZenDoor+ is a rugged wireless beacon designed for door status monitoring and temperature monitoring in demanding environments such as trailers, containers, and warehouse doors.

The device uses a TFT Eddystone data payload protocol (default) to transmit door and temperature data to compatible gateways and telematics platforms. With an IP67-rated enclosure and long battery life, ZenDoor+ is ideal for long-term, low-maintenance deployments.

2. Key Features

  • Door status monitoring

    • Detects whether the door is open or closed using a magnet-based sensor.

  • Temperature monitoring

    • Continuously monitors ambient temperature in the installation area.

  • Rugged design (IP67)

    • Water-resistant and dust-tight housing suitable for harsh environments.

  • Long battery life

    • Approx. 1,650 days of operation (under typical usage conditions).

    • Non-replaceable battery – designed for sealed, maintenance-free operation.

  • Wireless transmission

    • Transmission range up to 200 meters (line-of-sight; actual performance may vary based on environment and obstructions).

  • Standard data protocol

    • TFT Eddystone data payload protocol (default configuration).

  • Door Closed Detection Distance:

    • The beacon and its magnet must be within 3 centimeters to reliably detect door closed status.

4. Operation & Behavior

4.1 Device Activation

ZenDoor+ uses a front light sensor to power on and activate the device:

  • When exposed to light (e.g., removing it from packaging, installing in a lit environment), the device powers on and begins normal operation.

  • Once activated, it starts broadcasting its data payload at the configured interval using the TFT Eddystone protocol.

Note: Avoid covering the front light sensor when performing initial activation.

5. Door Sensor Setup & Configuration

Door sensor functionality is enabled and configured using the TFTBLE mobile application.

5.1 Requirements

  • Mobile app:

    • TFTBLE app installed on your smartphone or tablet

    • Available on Apple App Store (iOS) and Google Play Store (Android)

  • Physical access to the ZenDoor+ device and its QR code label.

  • Default configuration password: 654321

5.2 Enabling the Door Sensor (Step-by-Step)

  1. Install TFTBLE App

    • Download and install TFTBLE from the Apple App Store or Google Play Store.

  2. Open the App

    • Launch the TFTBLE application on your mobile device.

  3. Search for the Beacon

    • On the top-right corner of the app, tap the search option to add or locate devices.

  4. Scan the Device QR Code

    • Use your phone’s camera to scan the QR code printed on the ZenDoor+ device.

    • The app will associate this QR code with that specific beacon.

  5. Open Configuration

    • After the device is found, tap Config (or Configure) to access the device settings.

  6. Enter Password

    • When prompted, enter the default password: 654321.

  7. Enable Door Sensor

    • In the configuration screen, locate the Door parameter or Door toggle.

    • Toggle the “Door” switch ON to activate the door sensor functionality.

  8. Save / Apply Settings

    • Confirm or save the configuration in the app so the changes are written to the beacon.

  9. Do Not Modify Other Parameters

    • Unless specifically instructed by your system integrator or support team,
      do not modify other configuration settings (e.g., transmission interval, TX power, protocol mode, etc.).

    • Changing these may affect battery life, communication range, or integration behavior.

6. Installation Guidelines

6.1 Door & Magnet Placement

To ensure accurate door status detection:

  • Mount ZenDoor+ on the door frame or a fixed surface.

  • Mount the magnet on the moving door (or vice-versa), aligned with the beacon’s sensor area.

  • When the door is closed, ensure:

    • The distance between the device and the magnet is 3 centimeters or less.

    • Alignment is as straight as possible to improve reliability.

If the distance is greater than 3 cm when the door is closed, the device may detect the door as open.

6.2 Environmental Considerations

  • Install within the specified operating temperature range (as defined by the hardware spec sheet).

  • Avoid fully enclosing the device in metal housings that can severely block the Bluetooth signal.

  • Ensure the front light sensor is not permanently obstructed during activation.

7. Battery & Maintenance

  • Battery is non-replaceable:

    • The unit is sealed to maintain IP67 protection and reliability.

  • Expected battery life is approximately 1650 days under default settings and typical operating conditions.

  • When battery life is exhausted, the device will stop transmitting and must be replaced.

For fleets and large deployments, plan a replacement cycle aligned with the expected battery life.

8. Best Practices & Notes

  • Use only the TFTBLE app for configuration unless instructed otherwise.

  • Always enable the Door sensor via the Door toggle as described above; do not modify other advanced settings without guidance.

  • Verify door status readings in your gateway or telematics platform after installation:

    • Open and close the door and confirm that “open/closed” states are reported correctly.

  • Document the device ID and installation location (e.g., trailer number, door position) for easier support and troubleshooting.
