The Smart Battery Monitor connects via Bluetooth® using the RedVision App, not the device’s native Bluetooth® settings. Pairing is done by putting the monitor into pairing mode, selecting it in the app, and completing the request once the Status LED turns solid blue.
If Bluetooth® connection is lost or intermittent, users should delete the device from both the app and phone settings, restart the phone, clear pairings on the BSEN500, and then re-pair following the setup steps. Connection issues can also occur if multiple devices try to connect at once or if the app is left running in the background and moves out of range.

- Smart Battery Monitor (BSEN500)
Here is how to successfully establish a Bluetooth® connection for the Smart Battery Monitor and the tips and tricks for your Bluetooth® connection if it stops working.

Bluetooth® pairing
To successfully establish a Bluetooth® connection to the BSEN500, follow these steps:
- Download the RedVision App using the QR code above.
- Ensure Bluetooth® is switched on your device
- Press the Control button on the BSEN500 for 0.5-3 seconds then the Status LED will flash Blue and the BSEN500 will enter Bluetooth® Pairing Mode.
- Open the RedVision® App and allow the required permissions if it's the first time using the App. Then, tap the Menu Icon . Under the devices heading, tap the green Add Icon (+).
- Find and select the device that matches the Product Serial Number on your Battery Monitor
- Read and agree to the disclaimer.
- When the Bluetooth® pairing request appears, tap Pair (first time pairing may take a few moments).
- Once the Status LED turns solid Blue, and the system information appears on your smartphone, the Bluetooth® pairing is now complete.
Note: When establishing the Bluetooth® connection for the Smart Battery Monitor, ensure you are connecting through the RedVision App and not through the Bluetooth® settings on your device.

Troubleshooting a lost or intermittent Bluetooth® connection
If you are having difficulty establishing a Bluetooth® connection, here is the Bluetooth® troubleshooting guide to address your connection issues, follow the steps listed below:
- In the RedVision App, Tap the Menu Icon to navigate to the list of devices, locate your Battery Monitor device and delete it.
- Clearing Bluetooth® Pairing on the device - In your smartphone's Bluetooth® settings, remove the Battery Monitor from your Bluetooth® devices list.
- Switch off and re-start your smartphone.
- Clearing Bluetooth® Pairings on the BSEN500 — Ensure the Battery Monitor is in Bluetooth® pairing mode (Status LED is flashing Blue), then hold the Control Button for 5 seconds or until the Status LED begins to flash rapidly. Once the Status LED stops flashing rapidly, all Bluetooth® pairings are cleared from the Battery Monitor.
- Once successfully cleared, follow the Bluetooth® pairing instructions listed above.

Troubleshooting 'No Device Selected' and no device information
This can occur when the Bluetooth® connection is lost between a device and the BSEN500.
- If multiple devices are used to connect to a BSEN500 at the same time, this can contribute to connection issues and one of the two devices will lose its Bluetooth® connection.
- The RedVision User app is left open and running in the background on your smart device and you move out of range of the system. Simply close and re-open the RedVision App, then recheck operation.
- If the above are determined not the cause, carry out the procedure listed above to clear and re-pair the BSEN500 and smart device (smartphone/tablet).
Note: For an improved user experience, once you are finished using the RedVision App, it is recommended to close the app rather than leaving it running in the background as this improves the app reconnection speed when opening the app next time and avoids any unnecessary connection lag.
