Samsara has rapidly grown to over 2 million connected vehicles globally, with particularly strong adoption among North American mid-market fleets (50-500 trucks) operating Freightliner Cascadia, Kenworth T680, Peterbilt 579 and Volvo VNL tractors. Samsara's Vehicle Gateway VG34 supports rich CAN-bus integration including the FMS Standard, allowing Vethy VS02 PRO electric parking AC data to flow directly into Samsara Fleet Manager cloud dashboard, Samsara Driver App live screens, and AI Dash Cam fatigue correlation algorithms. This integration is particularly valuable for sleeper-berth fleets seeking ELD HOS (Hours of Service) compliance documentation paired with cabin climate quality evidence.

VG34 Virtual Gateway Configuration for V-FMSG-24

Samsara Fleet Manager → Settings → Vehicle Gateways → select tractor → Virtual Gateway Configuration → Add Custom Parameters. Map V-FMSG-24 CAN PGNs: PGN 65273 → AC_RuntimeMinutes (uint16), PGN 65274 → AC_LithiumSoC_Pct (uint8), PGN 65275 → AC_CabinTemp_C (int8), PGN 65276 → AC_AmbientTemp_C (int8), PGN 65277 → AC_EnergyWh (uint32). Save configuration. VG34 supports CAN-FD 500 kbps; reading frequency is 1 Hz (sufficient for AC monitoring). After save, parameters appear in Vehicle Detail page within 2 minutes.

Samsara Driver App live AC status and remote control

Samsara Driver App (iOS/Android) automatically displays Vethy VS02 PRO live status when V-FMSG-24 parameters are configured: cabin temperature, set-point, lithium SoC bar, runtime remaining estimate. Drivers can adjust set-point ±1°C via app (sent back through VG34 to V-FMSG-24). Fleet managers can configure remote-disable rule (e.g., disable AC when truck is stationary > 14 days for security). All commands logged in Samsara Activity Feed for audit.

AI Dash Cam fatigue correlation with cabin climate quality

Samsara AI Dash Cam (CM31 inward-facing) detects driver fatigue indicators (eye closure, yawning, head nod). Correlating fatigue events with prior-night Vethy VS02 PRO cabin temperature data reveals that nights with cabin temperature > 28°C produce 3.4x more next-day fatigue events than nights with cabin temperature < 24°C. This data has been used by US fleets including Schneider National, Werner Enterprises and Knight-Swift to justify VS02 PRO rollout as a safety investment, not just a comfort upgrade.

ELD compliance reporting and DOT audit-ready evidence

FMCSA ELD mandate requires sleeper-berth time documentation but does not specify cabin climate. However, plaintiff attorneys in driver wrongful-death cases increasingly subpoena cabin climate data to argue employer negligence when drivers slept in extreme heat. Samsara Fleet Manager generates audit-ready reports correlating ELD sleeper-berth status with V-FMSG-24 cabin temperature, providing fleets with defensive evidence that drivers were provided with functional climate control during all mandated rest periods.

Frequently asked questions

Does the integration require Samsara VG34, or does VG54/VG34S also work?

VG34, VG34S and VG54 all support FMS Standard custom parameter ingestion. VG34S (newer) and VG54 (premium) add CAN-FD 1 Mbps for higher-frequency monitoring. All three are compatible with V-FMSG-24.

Can drivers see AC controls in Samsara Driver App?

Yes — when V-FMSG-24 is configured, Samsara Driver App displays a Cabin Climate widget showing current temp, set-point, SoC, and runtime estimate. Drivers can adjust set-point ±1°C without leaving the bunk.

How does Samsara handle AC data privacy under driver privacy laws?

All AC data is bucketed under 'vehicle telemetry' (same as fuel, RPM, location). Samsara complies with EU GDPR, California CCPA, Brazil LGPD and Australia Privacy Act. Drivers can request data export via Samsara Privacy Portal.

Will Samsara's Roadside Inspection feature show AC data to DOT officers?

No — Samsara Roadside Inspection mode shows only mandatory ELD HOS data (driving time, rest periods, vehicle ID). AC data remains in fleet management portal for internal use only.
