Adding & Managing Devices

VoltSyncra discovers nearby BLE equipment, probes unfamiliar devices, and stores the information needed to monitor registered equipment.

Scanning

Scanning listens for nearby Bluetooth Low Energy advertisements. A device does not necessarily need to be actively connected in order to appear. Keep the application near the equipment and avoid running another application that holds an exclusive BLE connection while troubleshooting.

Tip: if a device is visible in the manufacturer's app but not VoltSyncra, fully close the manufacturer's app and scan again. Some BLE devices accept only one active connection.

How the scan list is organized

Unregistered supported batteries and other equipment are presented separately from unfamiliar devices. Devices already saved in VoltSyncra appear in the Already Registered section rather than being offered for registration again.

Probing unknown devices

If VoltSyncra cannot identify a device from its advertisement, you can run a protocol probe. A successful probe can identify supported battery telemetry. If no supported protocol responds, VoltSyncra keeps the technical probe details available so you can copy them or prepare an email to support.

An unidentified device can also be saved as Unknown. This preserves its device identity and diagnostic fingerprint without pretending that live telemetry is supported.

Registered devices

Registration tells VoltSyncra which discovered devices belong to your system. It stores the selected protocol/device type so VoltSyncra does not have to probe every device whenever the application starts.

Use meaningful names. If you have multiple identical devices, include location or purpose in the name.

Dashboard states and controls

Connecting: VoltSyncra is currently attempting to obtain a reading.
Live: A current reading has been received from the device.
Offline: The current attempt did not produce a usable reading. Use Retry for that device or Refresh All for the dashboard.
Canceled: The current connection attempt was manually stopped.
Details: Opens technical information when diagnostics are available. Diagnostics can be copied or sent to support.

PINs and Victron keys

A Bluetooth PIN and a Victron Instant Readout key are different credentials. VoltSyncra provides a general PIN field for equipment that requires Bluetooth pairing/authentication. Victron Instant Readout uses a separate 32-character hexadecimal key shown in VictronConnect. A PUK is a recovery credential and should not be used in either field.

Read-only monitoring

VoltSyncra's monitoring design is read-only. JBD/Xiaoxiang and other command-based integrations are restricted to explicitly reviewed telemetry requests; write/control commands are blocked by the application.
