No retrofit inside the pump
FERP taps the signal already going to the dispenser's display. The pump's own metering and certification are untouched.
Product
FERP: every sale at the pump, accounted for.
A small board fitted at the dispenser reads each fuelling transaction as it happens, sends it to the cloud, and prints the customer's receipt at the pump. Running today across 12 filling stations.
FERP is the hardware layer. The station owner's side of it — billing, accounts, stock, staff and credit customers — is MyFuelStation, running on these boards at the same 12 stations.
The problem
The dispenser already knows. It just never tells anyone.
A fuel dispenser computes litres and price for every sale and shows them on its display. That number reaches the customer and nobody else. Reconciling the day's takings means reading totalisers by hand and trusting the paperwork in between.
Transaction-level detail
Not just a daily total: nozzle up and down, litres, price and the running totaliser, timestamped per sale.
Works with what you have
Sanki, Censtar and Wayne display protocols are supported, with per-site configuration for other pump types.
How it works
Five steps, from the display line to your records.
Tap the display line
The COM board is fitted inside or beside the dispenser and connects to the display lines and power through a custom harness.
Decode the transaction
A dedicated display-tap chip reads the protocol and works out nozzle state, litres, unit price and the pump totaliser for each sale.
Send to the cloud
Each sale and status event goes to the CubeSphere cloud over HTTPS. A parallel MQTT link carries commands, configuration and updates.
Print at the pump
When the attendant presses the print button, a thermal printer issues the customer's receipt — over UART or USB, depending on the model.
Keep a local record
An SD card logs everything on site and a DS1307 RTC keeps time, synced with NTP. A dropped connection delays data; it does not lose it.
The equipment
Hardware line-up.
| Item | Detail |
|---|---|
| COM board v1 | Board "2308" — ESP32 main chip with an ESP07 display-tap chip. |
| COM board v2 / v3 | ESP32 main chip with an ESP32 display-tap chip. The current line. |
| Receipt printer (COM) | ESP32 board driving a thermal printer over UART. |
| Receipt printer (USB) | ESP32-S3 board driving a USB thermal printer. |
| Cable harness | Custom harness connecting the COM board to the dispenser's display lines and power. |
| Test rig | Display emulator that imitates a Sanki or Censtar dispenser, for bench testing without a live pump. |
Typical fit-out is one COM board per dispenser — covering one or two nozzles — plus one or more receipt printers per station.
Support
Most problems are fixed without anyone driving to the station.
Our support console shows the whole fleet: which boards are online, what firmware they are running, when each was last seen, and the cloud log for any device. Configuration can be read and written remotely, and snapshots are kept so a change can be rolled back.
When a fix is ready it goes out as an over-the-air update — in batch across the fleet if needed. A site visit is for swapping hardware, not for diagnosis.
- Live fleet view: online state, firmware version, last seen
- Remote configuration read and write, with snapshots
- Batch over-the-air firmware updates
- Per-device cloud logs, collected continuously
- Full audit log of every change made
- On-site serial log viewer for the rare hands-on case
In the field
Deployed and supported, not piloted.
12 stations live
FERP equipment runs in production at twelve filling stations, including sites at Nawinna, Makola, Yakkala and Dambulla.
About two support calls a week
Across the whole fleet. The equipment is built to be quiet, and most of what does come in is handled remotely.
Built in small batches
Boards are assembled, flashed and bench-tested in batches as each new station is fitted, so what ships has been run first.
