Teltonika Connection Lost
Severity: High
Applies to: Teltonika lock connections

What is a Teltonika device?
A Teltonika device (TRB141 or TRB142) is an IoT gateway installed near your doors that communicates with Unloc over the internet. It receives unlock commands from Unloc and triggers doors to open. Using a breakout card, a single Teltonika device often controls several locks — meaning a connection loss may affect multiple doors.
Why does this happen?
- Power loss — The Teltonika device has lost power.
- Internet connectivity — The device is not connected to the internet.
- Intermittent network issues — The device may have experienced network instability, leaving it in a disconnected state.
How to fix it
- Verify that the Teltonika device has power.
- Check that the device has an active internet connection.
- Power cycle the device — this often resolves intermittent network issues.
- If the problem persists, contact your installer to inspect the device and installation.
If you're unable to resolve the issue, contact Unloc Support.
