UniGuard's wired fuel-monitoring vehicle tracker on the JT/T 808 (Huabao) protocol · pairs a fuel-level sensor with position so a fleet reads tank and location together, decoded natively by Traxelio through Traccar.

Vehicle Types
UniGuard, a Shenzhen telematics maker, which markets the UM777 as a fuel-monitoring GPS tracker. It is grouped under the Huabao protocol here because it reports over JT/T 808, the Chinese fleet standard that Traccar labels "huabao".
Fuel monitoring. Its fuel-level sensor input turns tank readings into a fuel graph next to the route, which a plain GT06 unit does not do out of the box. If you do not need fuel data, a GT06 (Concox) or Teltonika unit is easier to source locally.
Yes, through the JT/T 808 (Huabao) driver in Traccar that Traxelio includes. Send the standard server-configuration command and it reports to Traxelio without any firmware change.
Only if you specifically need its fuel monitoring. It runs on 2G/GPRS available across Senegal, but the device is rare here and its app is Chinese-first · most local fleets pick GT06 or Teltonika hardware with local install support.
Overview
The UM777 is a wired vehicle GPS tracker built by UniGuard around fuel monitoring · a fuel-level sensor input feeds tank readings alongside position. It reports over the JT/T 808 (Huabao) protocol that Traxelio decodes through Traccar, so a fleet watches location and fuel on one dashboard. Common in Chinese and JT/T 808 export fleets, rare in West Africa.

The fuel-level sensor needs calibration against the real tank · take readings at empty, half, and full and enter the curve. Until it is calibrated the graph swings; a proper calibration table settles it.
Skip the vendor app. Send the server-endpoint command by SMS (Traxelio onboarding ships the exact JT/T 808 strings). The device reports the same regardless of which platform configured it.
JT/T 808 carries fuel and I/O in extension subfields that vary per OEM. Confirm the firmware emits them and that the server command requested the extended report, not position-only, then Traxelio maps the fuel channel.
