Frequently Asked Questions

Does VoltSyncra require internet access to read nearby Bluetooth devices?

No. BLE telemetry is local. Internet access is required for registration, email confirmation, sign-in, password recovery, device activation, and periodic server entitlement validation. After a successful validation, VoltSyncra can continue using a valid cached entitlement for up to 30 days while the server is unreachable, but never past a known trial or access expiration date.

Will I have to sign in every time I open the app?

No. VoltSyncra stores the activated device session securely and attempts to renew/validate it silently. If the server is temporarily unreachable and a valid offline authorization is available, the app can continue without forcing another login.

When does the 30-day trial start?

The trial starts after a device is successfully activated, not simply when the account is created.

What if I forget my password?

Use Forgot password? on the Sign in tab. The reset link is delivered by email for confirmed accounts.

Does VoltSyncra configure my chargers, shunts, batteries, or inverters?

No. The monitoring architecture is designed to be read-only. Protocols that require a request packet are restricted to reviewed telemetry operations; control/write commands are not part of normal monitoring.

Why can the manufacturer's app see a device when VoltSyncra cannot connect?

Manufacturers may use private protocols, firmware-specific behavior, or exclusive BLE connections. Confirm the exact model and firmware and close the manufacturer's app before testing VoltSyncra.

Why does a device show up but VoltSyncra cannot identify it?

BLE discovery and telemetry decoding are separate steps. Run the protocol probe. If no supported protocol responds, you can copy/send the probe diagnostics and optionally save the equipment as an Unknown device for future support.

Can I use several identical devices?

Yes. Give them physical names that make sense in your installation, such as Port MPPT, Starboard MPPT, House Shunt, or Starter Battery.

What is the best reference for a whole battery bank?

A properly configured shunt is an important reference for total current and consumed amp-hours because it measures the current entering and leaving the bank as a whole. Individual battery BMS readings remain useful for identifying imbalance.

Should I delete and re-register a device when it fails once?

Usually no. Use Retry, Refresh All, and the Details diagnostics first. Temporary BLE timeouts can occur, and diagnostic information is more useful than repeatedly recreating the registration.

Where should I start when asking for support?

Use the Send Support Report option on the About page, the Details dialog for a problem device, or see Diagnostics & Support.
