Why AV360-RS485

Built for Genset &
Industrial Monitoring

Real-Time RS485 Polling
Polls Modbus RTU devices every 1 second. Configurable register maps for DSE7320 and any standard Modbus controller.
Systemd Managed Service
Monitoring script runs as a systemd service with auto-restart. Survives reboots and network drops without manual intervention.
Offline Data Buffering
Stores telemetry locally during cellular outages. Automatically syncs to ThingsBoard when connectivity is restored.
Remote SSH Access
WireGuard VPN tunnel or reverse SSH for remote diagnostics and firmware updates — even behind cellular NAT.
Dual RS485 Channels
Two independent RS485 ports enable simultaneous connection to genset controller and fuel/level sensor at different baud rates.
ThingsBoard Native
Publishes to ThingsBoard via MQTT Gateway API format. Works with both local CE server and cloud deployment out of the box.
