Victron Devices

VoltSyncra supports read-only Victron BLE monitoring through Instant Readout advertisements and selected connected GATT paths, depending on the product and firmware.

Victron data paths in VoltSyncra

Victron Instant Readout uses encrypted BLE advertisements and does not require an active GATT connection. When this path is available, VoltSyncra uses the device's 32-character hexadecimal Instant Readout key.

Victron GATT is a connected BLE path used for selected equipment that does not provide usable Instant Readout telemetry. Some connected devices require the six-digit Bluetooth PIN saved when the device is registered.

Common Victron equipment recognized by the current integration

SmartShunt / Battery Monitor
Battery-monitor telemetry such as voltage, current, power, SOC and capacity-related values when exposed by the selected protocol.
Solar Charger / MPPT
Battery, PV, charger-state, current, power, and yield-related values when the selected Victron record/protocol supplies them.
Inverter
Instant Readout record types for supported Victron inverter families are recognized, with available telemetry depending on record type.
DC/DC and SmartLithium families
Some Victron Instant Readout product families are recognized; the exact fields available depend on the BLE record exposed by the product.

Finding the Instant Readout key

In VictronConnect, open the product information and the Instant readout details view, then choose SHOW. VoltSyncra expects 32 hexadecimal characters (16 bytes). This key is separate from the six-digit Bluetooth PIN.

Keep the key private. Do not include the Instant Readout key in screenshots, public posts, or manually entered support messages.

Older Victron devices

Victron has used more than one Bluetooth data path across product generations and firmware versions. A device being visible in VictronConnect does not prove that it supports Instant Readout.

VoltSyncra detects the capabilities actually exposed by the device. Older equipment may use a connected GATT path instead of encrypted advertisement readout.

Before troubleshooting VoltSyncra

  1. Confirm the device is visible and readable in VictronConnect.
  2. Record the exact product name, part number, and firmware version.
  3. If testing a connected GATT path, fully close VictronConnect first.
  4. Verify that the saved Bluetooth PIN or Instant Readout key matches the data path being used.
  5. Keep the phone/computer near the Victron device.
  6. Use VoltSyncra Details/diagnostics to capture the detected protocol and failure stage.

VE.Smart Networking is different from VoltSyncra monitoring

VE.Smart Networking allows compatible Victron products to exchange selected measurements and coordinate charging. Seeing a Network option in VictronConnect does not indicate which third-party BLE readout path a product exposes.

What to include in a Victron support report

  • Exact product name and part number.
  • Firmware version shown by VictronConnect.
  • Whether VictronConnect was fully closed during a connected-BLE test.
  • Platform and OS version.
  • VoltSyncra scan/probe result and selected protocol.
  • The VoltSyncra Details text and relevant log excerpt.
  • A screenshot of the values VictronConnect shows for comparison, with credentials hidden.
