Bring your EVBox
charger back to life

EVBox's EverOn backend is gone. Without it, your G2 or G3 charger is a very expensive doorstop. This small module replaces the modem and makes your charger function stand-alone — no subscription, no backend, no fuss.

Overview

What the autostart module does

EVBox G2 and G3 chargers rely on a backend to make all decisions. When EVBox shut down their EverOn backend, in December 2025, your charger had nobody to talk to — and stopped working. The autostart module steps in as a drop-in modem replacement, telling the charger everything it needs to hear to start charging.

🔌

Drop-in replacement

Plugs into the same connector as the original modem. No soldering, no modifications to the charger.

🌐

No backend required

Works entirely stand-alone. no cellular connection, no subscription, no backend of any kind.

⚡

Full autostart

Plug in a vehicle and it starts charging. Exactly what most home users want from their charger.

♻️

Prevent e-waste

Thousands of perfectly good chargers are being discarded because of a server going offline. This module gives them a second life.

Compatibility

Is your charger supported?

The module supports EVBox G2 and G3 chargers, both HomeLine and BusinessLine, produced between 2013 and 2020.

Identify your charger by serial number

Serial numbers starting with 2 are G2, and starting with B are G3.

21412801 ✓ B20449875 ✓ 320315124 ☓

The serial number is on a label on the side of the charger and also inside the housing.

Identify your charger by model number

Model numbers follow the pattern: H1161-1000 - one letter, four digits, a hyphen, then more digits. The module supports models where the first digit after the hyphen is 1 through 6.

H1161-1001 ✓ B3162-1100 ✓ H1161-5001 ✓ H1320-50082 ✓ B3162-E1901 ☓
⚠️ Not sure? If your charger looks like the standard EVBox HomeLine or BusinessLine wall unit and was installed before 2021, it is very likely supported. When in doubt, feel free to get in touch before ordering.

Installation

If you can build Ikea furniture,
you can install this

Installation requires opening the charger and swapping the modem. That's it. No tools beyond an Allen key, no electrical knowledge required.

1

Open the charger

Remove the cover of the EVBox unit. An Allen key is all you need.

2

Unplug the original modem

Disconnect the modem from its four-pin connector and set it aside.

3

Plug in the autostart module

Connect the autostart module to the same connector. It fits only one way.

4

Close the charger and you're done

Refit the cover. Plug in your vehicle and it will start charging automatically.

🔧

Build it yourself

Source the components, fabricate the PCB, and flash the firmware yourself. Everything is open source.

See the project Raspberry Pi logo

Raspberry Pi solution

Use a Raspberry Pi to emulate the modem. More configurable, but requires a Pi and some Linux know-how.

Configure a new backend

Build a USB dongle and reconfigure the charger to connect to a different OCPP backend.

Background

How this came to be

This module is the result of three years of tinkering with EVBox chargers – starting with one charger and one question: why does this thing need the internet to charge my motorcycle?

Managed EV charger to stand-alone

The original project: reverse-engineering the EVBox protocol and replacing the modem with a Raspberry Pi to make one charger work without any backend at all. This is where the protocol was documented.

Reversing the EVBox ChargeStation Tool

A deeper dive into the EVBox configuration tool, making it possible to point an existing modem at a different OCPP backend — for those comfortable with that approach.

The autostart module

When EVBox's EverOn backend went offline and readers started asking for a simple solution, these two projects came together into a small drop-in module. It runs an embedded version of the original Raspberry Pi project.
