Step 1: Install the Vethy VS02 PRO Add-In from Geotab Marketplace
Log into MyAdmin → Marketplace → search 'Vethy Parking AC' → click Install. The Add-In is published by Vethy under category 'Telematics Add-Ins / Auxiliary Equipment'. Installation takes 30 seconds and grants MyGeotab access to Custom Data parameters: AC_RuntimeHours, AC_LithiumSoC, AC_CabinTemp, AC_AmbientTemp, AC_EnergyWh, AC_StatusCode. The Add-In supports MyGeotab versions 2401+ and is compatible with all Geotab GO devices (GO9+, GO9, GO8 with IOX-CAN expansion).Step 2: Configure IOX-CAN expansion module on existing GO9+ device
Vethy VS02 PRO requires Geotab IOX-CAN expansion module (PN: GT-IOX-CAN) connected to GO9+ device. Plug IOX-CAN into GO9+ expansion port, then connect 4-wire harness to V-FMSG-24 FMS gateway (CAN-H, CAN-L, +12V, GND). In MyAdmin → Devices → select the truck → Expansion Modules → Add IOX-CAN → Configuration: Baud Rate 250 kbps (CAN-FD auto-detect), Termination Resistor ON, PGN Filter 65273+65274 (Vethy AC PGNs). Save and reboot device. Within 5 minutes, AC Custom Data parameters appear in MyGeotab Live Map.Step 3: Build Rules Engine alerts for low SoC and excessive runtime
MyGeotab → Rules → New Rule. Common rules for Vethy VS02 PRO fleets: **Low Lithium SoC Alert**: AC_LithiumSoC < 30% during driver rest period → email/SMS to fleet manager + push to driver Geotab Drive app for early engine restart. **Excessive AC Runtime**: AC_RuntimeHours daily > 12h → flag for maintenance review (potential thermostat fault or insulation degradation). **Cabin Temperature Out-of-Range**: AC_CabinTemp > 28°C during set-point < 22°C → potential refrigerant leak or compressor fault. **Energy Consumption Anomaly**: AC_EnergyWh per hour > 350Wh (normal 200-280Wh) → potential lithium cell degradation.Step 4: Driver coaching reports and per-driver AC usage benchmarking
Report Builder → New Custom Report → Data Source: Custom Data AC_EnergyWh, AC_RuntimeHours, Driver. Group by Driver, aggregate Average per night, percentile rank across fleet. Top 10% efficient drivers achieve 180-220Wh/h average (proper set-point 22-24°C, door discipline); bottom 10% consume 320-400Wh/h (set-point 18°C, frequent door opening). Use this data for driver coaching: 1°C cooler set-point increases lithium drain ~15%, doubling battery cycle wear. Coaching can extend lithium bank life from 8 years to 11-12 years across the fleet.Frequently asked questions
Does the Geotab Add-In work with GO8 devices or only GO9+?
GO9+ is preferred for full IOX-CAN-FD support and is required for Samsara/Webfleet-equivalent feature parity. GO8 works with IOX-CAN (legacy 250 kbps CAN) but limited to AC_RuntimeHours, AC_LithiumSoC, AC_CabinTemp (no CAN-FD high-rate diagnostics). We recommend GO9+ for new deployments.
How accurate is AC_LithiumSoC reading?
V-FMSG-24 reads SoC directly from the BMS (battery management system) inside the VS02 PRO LiFePO4 200Ah bank, with ±2% accuracy after coulomb-counting calibration. SoC is more accurate than voltage-only estimation used by older lead-acid AC systems.
Can I use Geotab Rules Engine to auto-start the truck engine when SoC is low?
Direct engine start command is not possible (and not desirable for safety/security). However, Rules Engine can push a Driver Geotab Drive app notification recommending engine restart at SoC < 30%, and fleet managers can configure a phone-call escalation via Geotab Marketplace integrations (Twilio, AWS Connect).
Does AC monitoring data sync to MyAdmin reseller portal?
Yes — MyAdmin reseller portals receive all Custom Data parameters via Geotab API. Resellers can build white-label fleet AC dashboards for their customers, common across North American Volvo Trucks dealers, Penske Truck Leasing and Ryder System.
