01 / For integrators, property managers & employers

Bookings that switch the power.

We make existing charge points bookable and switch them physically – without replacing the wallboxes. Fair time slots instead of parking-lot fights. Retrofit for a fraction of a wallbox swap.

01

No swap

existing wallboxes stay – retrofitted, not replaced

02

Gulf region

building complex, white-label under the operator brand

02 / Context

You know the problem

More EVs than charge points. First come, first served – everyone else is frustrated. Calendar tools don't help because nobody has to obey them. And new smart wallboxes cost €1,500–2,500 per point plus electrician hours.

01

Book instead of hope

Users reserve time slots via app or browser – with fair rules, reminders and automatic completion.

02

Enforced, not just noted

The charge point is physically switched on for the booking and off afterwards.

03

Fail-safe by design

Every switch-on command carries a local auto-off timer inside the device. If the internet or server dies, the charging session still ends on time – proven under test.

Our principle

“A booking with us is not a calendar entry. It is power.”

03 / System

How the retrofit works

01 — Distribution board

Measure & switch

Per charge point: an industrial energy meter with contactor control in the distribution cabinet. The load current stays where it belongs – the wallbox stays untouched.

02 — TLS / LTE

Secure connectivity

Devices connect encrypted (TLS) via an outbound connection – no port forwarding, no VPN, works over an LTE router per building.

03 — Per device

Commissioning in minutes

Technicians provision devices with a setup script or directly in the browser via Bluetooth. Every device reports to the dashboard within seconds – acceptance testing is part of the software.

04 — 24/7 operations

Operations & monitoring

Live status, power telemetry, offline alerts and a complete switching audit trail. Manual override for facility management included.

04 / Hardware

Works with your hardware

Two paths to a controllable charge point – depending on what is already on your wall.

Universal

Retrofit – any wallbox

Metering and switching gear in the distribution cabinet makes any existing wallbox controllable – including devices without any interface, like the Tesla Wall Connector. Hard switch-off guarantee through the local fail-safe timer inside the device.

  • Tesla Wall Connector
  • Heidelberg
  • ABL
  • Webasto
No extra hardware

Smart wallboxes – direct cloud API

Wallboxes from Zaptec, go-e and Easee connect directly through the manufacturer API – live status and charging data today, active slot switching as a project deliverable. No work in the distribution cabinet required.

  • Zaptec
  • go-e
  • Easee

Other manufacturers or a mixed fleet? That is exactly what the project business is for – talk to us.

05 / Current project

One building complex, one white-labeled platform

For a building complex in the Gulf region we are retrofitting existing wallboxes without any interface with metering and switching gear – booked through a fully white-labeled platform under the operator's own brand. Without replacing a single wallbox.

  • Existing hardware without OCPP – retrofitted, not replaced

  • White-label: own domain, own branding, own app

  • Fail-safe proven under stress: charging ends on time even with the server down

06 / Partnership

The partner model

You bring the customer relationships and the electricians – we bring the platform and the hardware know-how. You sell under your brand; your customers only ever see you.

01

White-label platform on your domain, with your logo and colors

02

Hardware bill of materials, provisioning tools and an installation runbook

03

Fair partner terms per charge point, billed by invoice
