NMEA 2000 and proprietary edge protocol decoder
Marine edge hardware talks to the NMEA 2000 CAN bus and engine ports, processes PGNs and ECU streams, and turns them into standardised JSON.

Smart marine telemetry — NMEA 2000 LoRaWAN
Edge computing, NMEA 2000 protocol decoding and wireless LoRaWAN mesh
A vessel solution that brings engine protocols, compartment sensors and shore-side views together — without drilling through watertight bulkheads.
Executive summary
Smart marine telemetry
Vessel managers need reliable telemetry to protect operations, track fuel use and plan maintenance. Shipboard environments make that hard — complex maritime protocols, metal compartments and strict cabling limits.
WSmart built marine telemetry and environmental monitoring for a private vessel operator. An edge marine protocol converter decodes NMEA 2000 and proprietary engine data in real time, with an on-board LoRaWAN sensor mesh into WSmart.io.
The edge system decodes NMEA 2000 CAN bus PGNs and proprietary engine metrics, then sends standardised telemetry over cellular or satellite. LoRaWAN sensors watch bilge water, engine-room temperature and door status — without damaging watertight bulkheads or long field cabling.
The challenge
The challenge
- Complex maritime protocols: engine diagnostics, fuel rates, RPM, coolant temperature and navigation metrics run on NMEA 2000 CAN networks or proprietary ECU protocols that standard IoT gateways cannot interpret directly.
- Cabling cost and bulkhead integrity: drilling through steel bulkheads and watertight compartments risks hull integrity, may require classification approvals and creates high labour cost.
- Multi-faceted vessel health monitoring: shore-side teams need visibility into bilge water, battery-bank voltage, ambient heat and emergency door status in addition to engine performance.
- Intermittent connectivity at sea: offshore vessels experience fluctuating cellular coverage, so local edge buffering is needed to prevent telemetry loss during connection dropouts.
Architecture pillar
The solution · WSmart edge-to-cloud marine telemetry
WSmart designed a multi-tier maritime setup: local edge computing, protocol conversion, long-range wireless sensing and a central cloud view.
Wireless on-board LoRaWAN mesh
Sensors across watertight compartments, bilges and engine rooms track bilge-pump triggers, water ingress, temperature and humidity — no drilling or conduit runs.
Store-and-forward local caching
The WSmart Edge Gateway caches decoded telemetry during blackouts and syncs history when the link returns.
Centralised fleet cloud platform
The shore dashboard shows engine health — RPM, oil pressure, coolant temperature, fuel rate and running hours — plus fault codes, bilge-flood warnings and history.
Outcome
Results
- Zero structural alteration and 70% cable savings: wireless compartment sensing eliminated complex cable runs through watertight bulkheads and cut installation labour by more than 70%.
- Seamless legacy and NMEA 2000 integration: the edge converter bridge-decoded CAN messages and proprietary engine formats without engine replacement or intrusive controller changes.
- Proactive predictive maintenance: continuous shore-side telemetry helps engineers detect temperature spikes or pressure drops before catastrophic engine failure at sea.
- 360-degree vessel risk mitigation: immediate alerts for bilge-water ingress or compartment overheating support a fast response that protects crew and maritime assets.

Marine telemetry FAQ
Can marine vessel systems be monitored wirelessly without drilling watertight bulkheads?
Yes in many installs: edge protocol decoding (including NMEA 2000 context) plus wireless vessel monitoring reduces invasive cabling through watertight structure. You get one view for vessel sensors and alerts to shore or crew workflows. Classification or survey constraints need client-supplied wording before we publish them.
