Flo

Flo — field brand hub

Flo Smart Two AC units show up on workplace and public Level 2 pads. Ownership is the pedestal: pilot path, meter, auth card, and enclosure thermal — plus Flo network auth. Split “won’t authorize” from “authorizes but no energy” before you open the enclosure.

When this OEM shows up

Typical tickets: auth card not accepted, meter error, pilot diode fail (no charge with EV plugged), overtemp enclosure in sun/poor airflow. Site owns PE and feeder; Flo/CPO owns credential mapping; the unit owns pilot, meter, and local thermal path.

How faults present

• Local LEDs / display: meter error, overtemp, fault.
• Flo network / OCPP: Authorize rejected vs Faulted mid-session. Auth-only: /guides/fleet-cms-triage, /entries/protocol-ocpp-f03-authorize-rejected-invalid-idtag. Hard Faulted: /guides/ocpp-faulted-triage.
• Cloud: card credential mapping and meter register history.
• Physical: hot enclosure in sun, blocked vents, damaged cable/pilot pins.

Ranked failure patterns

1. Auth card not accepted — Credential/list/reader; not a pilot fault. Entry: /entries/flo-flo-st-auth-auth-card-not-accepted. Related: /entries/protocol-rfid-01-rfid-reader-no-uid.

2. Smart Two meter error — Meter path / CRC-class issues affecting session close. Entry: /entries/flo-flo-st-met-smart-two-meter-error. Metering guide: /guides/metering-payment, /entries/protocol-met-01-energy-meter-crc-error.

3. Pilot diode fail — CP path; EV never reaches charge-ready. Entry: /entries/flo-flo-st-pilot-pilot-diode-fail.

4. Overtemp enclosure — Sun load, blocked vents, failed fan if equipped. Entry: /entries/flo-flo-st-temp-overtemp-enclosure.

Logs / tools

Flo portal event log, Authorize timeline, LED photos, IR on enclosure, DMM on CP, known-good credential card, PE continuity (/entries/protocol-gnd-01-ground-continuity-fail-at-dispenser).

Escalate when

• Electrician: Supply issues, enclosure heat from upstream overload, wiring on pilot, PE problems.
• Network/Flo ops: Card not in allow-list, site group mis-map.
• OEM: Meter board or pilot hardware after credential and wiring cleared.

Do not OEM-escalate auth rejects that are credential-only.

Field checklist

1. Split the ticket: auth fail vs meter/pilot/thermal with auth OK.
2. Photo LEDs/display and note ambient sun load on the enclosure.
3. Pull Flo portal Authorize timeline and last good session.
4. Try a known-good credential before opening the pilot path.
5. If meter error: capture register/CRC evidence for /guides/metering-payment — do not treat as isolation.
6. If no charge after authorize: CP/pilot check and second vehicle when available.
7. Clear vents / shade path before condemning overtemp hardware.

Soft-offline with healthy local LEDs is backhaul/CSMS (/entries/protocol-ocpp-f02-heartbeat-timeout-to-csms), not a pilot diode.
