The Barn (Devon) Holiday Lets — Turning EV charging into a measurable guest service
A simple guest experience, automated charging and payment workflows, and clear operational insight from a connected Easee One charger.
The business
The Barn at Cob Tree Cottage, a Devon holiday rental associated with feeed.
From a physical charger to a service the host can understand, manage and improve.

01 / The opportunity
An amenity.
An operational need.
For some guests travelling in an electric vehicle, access to reliable self-service charging is something they actively look for when choosing accommodation. At The Barn, the opportunity was practical: let guests charge where they stay, without turning each charging session into an exchange of messages with the host.
At The Barn, charging is an amenity guests actively use. Around one in five guest groups arrives with an EV, and every EV-driving group has used the service during its stay — sometimes nightly. The opportunity was to turn that practical need into a straightforward guest service, backed by clear information for the host.

Guest-group figures are based on the host’s observations; charging activity below is recorded by the app.
02 / The challenge
A domestic charger.
A guest-facing service.
The installed charger is a domestic Easee One. Its normal companion app is not a self-service checkout and payment workflow for a succession of short-stay guests. Guests need a clear way to choose an amount of energy, pay and see what is happening; the host needs fair consumption tracking without manually piecing together each session.
The challenge was to join these needs up. Device control, metering, payment and the browser experience had to become one usable service, while retaining enough visibility to investigate charging attempts that did not deliver energy.
03 / What feeed built
A straightforward journey from QR code to charge
feeed developed Guest EV Charge Hub as a responsive, browser-based service. Guests enter through a QR code, without downloading a special app. They can see availability, select their desired kWh and view an estimated driving range before making a secure Stripe payment.

Receipt
A record of the charging session
The Easee API provides device control and metering data, bringing the physical charging session into the web app. Guests can monitor progress and receive receipts, rather than needing the host to interpret the charger’s companion app for them.
Session completion and refund processing are automated where supported, while management tools give the host visibility and control when an exception needs attention. The guest journey and the operational workflow are designed together.
04 / App-recorded evidence
A guest service with a measurable footprint
Nearly 500 kWh delivered, with a clear record of when and how it was used. The app turns everyday charging activity into useful operational evidence: energy supplied, consumption per session and activity over time.
- Energy supplied
- 495.6kWh
- Completed live-mode sessions with positive energy
- 21sessions
- Average per energy-delivering session
- 23.6kWh
- Days with recorded energy-delivering live charging
- 20days

Energy delivered by month
2026 / kWhMonthly data table
| Month | kWh | Coverage |
|---|---|---|
| June | 0.00 | 30 June only |
| July | 335.75 | Full month |
| August | 112.56 | Full month |
| September | 0.00 | Full month |
| October | 47.25 | 1–20 October only |
What this tells the host
July accounts for most of the energy delivered in this period. The monthly view makes peaks and quieter periods immediately visible, giving the host a starting point for reviewing demand, comparing future seasons and planning the service around actual usage.

Why the exceptions matter
The dashboard makes exceptions useful. “Cable disconnected” and “Car refused charge” give the host specific outcomes to investigate, helping focus attention on the sessions that need it.
06 / Management insight
Clear data to act on
The admin console brings tariff settings, charger status, sessions, refunds, discount codes, reporting and diagnostics into one place. It gives the operator a practical route from an observation to a decision, rather than simply displaying a running total.

Monitor demand
Review energy over time and look for demand or seasonal patterns worth investigating.
Understand consumption
Review delivery and consumption by session, including the difference between requested and delivered energy.
Reconcile money flows
Review payments and refunds alongside the charging sessions they relate to.
Inspect unsuccessful attempts
Use recorded outcomes and diagnostics to investigate sessions that transferred no energy.
Adjust the service
Manage tariffs and discount codes using operational context, not guesswork alone.
Identify problems
Review charger status and session evidence to decide where an operational issue needs attention.
07 / The feeed approach
Useful software.
Connected to real life.
feeed took a specific hospitality need and delivered a working bespoke web app that connects physical hardware, an API, payments and usable management data. The result is software shaped around the way The Barn operates.
For guests, there is a clear route from choosing their energy to paying, charging and receiving a receipt. For the host, charging becomes a manageable service: consumption is visible, payments and refunds can be reviewed, and exceptions can be investigated. The data supports practical decisions about how to run and improve the amenity.
This is the wider feeed approach to rapid custom software development: start with the operational need, connect the systems that matter, and make the resulting data useful for the people running the business.
