Profi Wi-Fi

Optim 3.0 is the reliable freight-transport tracker. It supports GPRS and SMS, integrates easily with LLS sensors, and is rated IP52. Profi 3.0 is built for extreme conditions, with wide voltage tolerance, heavy vibration resistance, IP54, used in mining, construction, and fuel tankers. Profi 3.0 Wi-Fi adds local-network data transfer for sites with no cellular coverage. All trackers carry a 3-year warranty.

Optim 3.0 is the right choice for delivery vans, light commercial diesel trucks, and freight fleets operating in areas with stable cellular coverage. It is the lower-cost tracker in the lineup and integrates with standard fleet management workflows. Profi 3.0 steps up to handle the abuse heavy diesel machinery delivers daily: temperature extremes from minus 40 to plus 85 Celsius, voltage spikes from auxiliary equipment, vibration from off-road operation, and dust ingress from quarries and construction sites. It is the recommended tracker for diesel excavators, haul trucks, drilling rigs, cranes, and tankers. Profi 3.0 Wi-Fi adds a critical capability for remote operations: when the vehicle returns to a Wi-Fi hotspot at the depot or worksite, it offloads buffered data automatically. This is the standard for mining fleets in remote areas, agricultural operations across large fields, and any site where cellular service is unreliable or expensive. All three trackers speak the OMNICOMM LLS protocol over RS-485, which lets partners pair them with OMNICOMM sensors or mix and match with third-party hardware.

Yes. The fuel level sensor itself is wired to a GPS tracker or terminal via RS-485 or MODBUS, so it does not depend on a cellular signal to operate. Cellular coverage is only relevant to the connected tracker, which buffers data locally when out of range and uploads it once a network is available again. No fuel data is lost during the gap.

The sensor measures fuel level once per second and outputs that reading on the digital RS-485 / MODBUS interface to whatever terminal is connected: an OMNICOMM tracker or any third-party tracker that supports the LLS protocol. From there, how the offline period is handled is a tracker question, not a sensor question. The terminal stores events in its onboard memory and uploads them on the next available link, whether that link is cellular, Wi-Fi, or a wired connection at the depot. For deployments where vehicles spend long periods out of cellular range (mining haul trucks in pit areas, agricultural tractors across large fields, forestry equipment, offshore vessels), the buyer chooses a tracker with sufficient local storage and the appropriate uplink. See this answer for the full remote-site workflow including how OMNICOMM and partner-supplied trackers handle offline buffering and periodic upload.

Remote sites without reliable cellular or wired internet are a core OMNICOMM use case. The fuel sensor itself is wired to a tracker via RS-485 / MODBUS and works independently of any network. The connected GPS tracker buffers events locally and uploads them on the next available link, whether that is cellular, Wi-Fi at a depot or fuel station, or a wired connection at base. No fuel data is lost during the offline period.

Mining haul trucks operating in pits with no cellular signal, agricultural tractors crossing fields beyond 4G coverage, forestry machinery deep in remote blocks, and offshore support vessels all share the same operating pattern: hours or days without an internet link, followed by occasional time at a base location. Any GPS tracker with enough onboard storage and a Wi-Fi or cellular uplink can handle this workflow; the choice depends on the buyer's existing fleet platform. OMNICOMM's Profi 3.0 Wi-Fi is one option and is built specifically for this pattern, with internal storage that buffers up to several weeks of detailed event data and automatic upload over Wi-Fi when the vehicle parks at a depot or fuel station hotspot. Third-party trackers that support the LLS protocol can deliver the same offline-then-upload behavior using their own buffer and uplink. Fides Mining in Brazil runs OMNICOMM sensors across a 260-vehicle fleet in remote Matupa using this approach. Agricultural and construction fleets in similar conditions follow the same workflow. For permanent installations on stationary generators or fuel tanks at remote sites, the same pattern applies: the chosen terminal handles offline buffering and periodic upload so a generator's daily fuel consumption is captured even when the site has no cellular service for weeks at a time.
