Setting up the Compleo eBOX without an app: Wi-Fi, LAN, backend and PV surplus

You can set up your Compleo eBOX in just a few minutes directly in your browser – no app needed. The wallbox has its own web interface, which you can open with any laptop or smartphone with a LAN adapter. In this article, we show step by step how to connect the eBOX to your network via Wi-Fi or LAN, link it to a backend, connect it to an energy management system and charge with PV surplus. You do not need the former eConfig app for this – it only runs on older Android devices anyway.

The Compleo eBOX at a glance

The eBOX comes in two lines: the eBOX smart is the slim wallbox for the home, while the eBOX professional adds features for businesses, residential complexes and billing, such as MID meters or versions compliant with Austrian and German calibration law (Eichrecht). Both charge at up to 22 kW and can be set up via the same web interface.

• Compleo eBOX smart socket – with Type 2 socket
• Compleo eBOX professional cable – with 6.5 m cable
• Compleo eBOX professional cable MID – with MID meter
• eBOX professional socket EKA and cable EKA – compliant with Austrian and German calibration law (Eichrecht)

You can read how installation with the eCLICK system works in our article Compleo eBOX & SOLO: easy installation with eCLICK.

What you need for setup

• Laptop or smartphone with LAN adapter (USB-C to Ethernet)
• A network cable
• The PUK of your eBOX – it is printed on the back of the operating instructions. You cannot log in without the PUK, so keep the instructions in a safe place.
• For Wi-Fi: network name and password. For LAN: a free IP address in your home network or DHCP on the router.

Important: Network port 2a (LAN2) is located under the cover of the eBOX. Work on the opened device may only be carried out by qualified electricians in compliance with protective measures.

Connecting to the web interface

1. Plug the network cable into port 2a (LAN2) of the eBOX and the other end into your laptop or smartphone.
2. If no address is assigned automatically, set your device to a static address of 172.16.0.2 with the subnet mask 255.255.255.0.
3. Open https://172.16.0.1 in your browser. The certificate warning is normal for this device – confirm and continue.
4. Log in with the user name admin and the PUK as the password.

After switching on, it takes the eBOX up to five minutes until the page is reachable. Save each section with OK.

Setting up the eBOX via Wi-Fi

Under Network → Interface:

1. Select wlan as the interface and tick active.
2. Enter the network name (SSID) and password – note upper and lower case.
3. Optionally, tick Static IP active and assign a fixed address.
4. Apply with OK.

Under Network → Status you can see whether the connection is established. If reception at the installation location is weak, a LAN connection is the more stable choice.

Setting up the eBOX via LAN: static IP or DHCP

LAN is the most stable connection and a prerequisite for Modbus. Under Network → Interface, Ethernet settings (net2):

• Static address: tick Static IP active and enter a free address from your home network and the subnet mask. Do not use the addresses 172.16.0.1 and 192.168.1.1.
• Automatic (DHCP): untick static IP or tick Start DHCP client. You will then find the address in your router's device list.

If the eBOX needs internet access, for example for a backend, select net2 as the interface under Network → Interface and tick active. Then unplug the laptop and connect the eBOX to your home network. From now on, it can only be reached at the new address.

Tip: For Modbus, load management and PV surplus, always use a static address or a fixed assignment in the router – otherwise the address may change after a restart.

Configuring the charging point correctly

Under LDP1 → General:

• Max. current to match the circuit protection of the supply cable, maximum 32 A.
• Number of phases: 1 or 3.
• Phase setting L1–L3: with several boxes, rotate the phases to avoid phase imbalance.

We explain why a wallbox connected on a single phase delivers less power in 11 kW or 22 kW wallbox connected on a single phase.

Connecting a backend (OCPP)

A backend gives you billing, access via charging card or app, and remote maintenance. The eBOX registers via OCPP, for example with Monta or eCarUp, and needs an internet connection to do so.

1. Under ECU → ACCU, set the operation mode to b2b and the protocol to OCPP-generic.
2. Under ECU → OCPP, enter the chargebox ID, endpoint URL (wss://…) and, if required, the password. You will receive this data from your backend provider.

Some backends restart the eBOX once more after the first connection – this is normal.

Load and energy management via Modbus

An external energy management system – for example Loxone – can set the charging current of the eBOX via Modbus TCP. This works with the eBOX smart and the eBOX professional. A static IP address is required; a wired connection is recommended.

1. Under LDP1 → Load management, select the type modbus_tcp, port 5555.
2. In case the connection is lost, select Control Computer and set a current limit of 6–10 A. This way the box keeps charging slowly instead of stopping.

Important: The eBOX only accepts one Modbus controller at a time.

More on this topic in Load management made easy.

Charging with PV surplus – one wallbox

The internal load management of the eBOX reads a smart meter at the house connection itself – for example the Shelly Pro 3EM – and charges your car with the electricity that the PV system currently has to spare. No additional energy manager is needed, and there are no running costs.

What you should know

• Start threshold: a wallbox charges with at least 6 A per phase. On a single phase, this corresponds to around 1.4 kW of surplus; on three phases, around 4.1 kW.
• Small PV system? On a single phase, charging starts earlier, but the grid operator's phase imbalance limit applies.
• Protection: the house connection is never loaded beyond the set maximum current.
• PV surplus via the internal load management and an external energy management system via Modbus are mutually exclusive.

How to set it up

1. Install the smart meter: Shelly Pro 3EM in the distribution board directly after the grid operator's meter, current transformers around all three line conductors, arrow pointing towards the house. (A job for a qualified electrician.)
2. Prepare the smart meter: static IP address in the same network as the eBOX; enable Modbus TCP in the Shelly settings.
3. eBOX as controller: assign a static IP; under LDP1 → Load management, select type modbus_tcp, interface net1 or wlan1, and tick Controller active.
4. Open the load management portal: via Open controller or https://<IP of the eBOX>:8087, log in with admin and the PUK. Set the max. current to the rating of the house connection fuse, with a reduction factor of e.g. 0.9 as a buffer.
5. Add the smart meter: enter the Shelly with its IP address and enable charging with PV surplus.
6. Secure and test: minimum current 6 A, fallback current e.g. 6 A. When the sun is shining, plug in the vehicle – the grid consumption at the meter should approach zero.

Frequently asked questions

The page does not load – what should I do?

Check the cable in port 2a and set your own address to 172.16.0.2 / 255.255.255.0. After switching on, the box needs up to five minutes.

The login is rejected.

The user name is always admin; the password is the PUK from the back of the operating instructions.

After a change, the eBOX can no longer be reached.

After some changes, the box restarts – wait a few minutes. After an IP change, it can only be reached at the new address; with DHCP, you will find it in the router's device list.

The eBOX does not charge.

Check under LDP1 → Authentication: with “none”, the box charges as soon as a vehicle is plugged in. With a backend, authorisation is given via the backend. If the box shows “out of service”, set the operational status under LDP1 to “operational”.

My car charges more slowly than expected.

Check the max. current and number of phases under LDP1 → General. Many vehicles only charge on one or two phases on AC – more on this in Why won't my plug-in hybrid charge at full power?

How do I check and update the firmware?

The version is shown under System → System data in the ACCU firmware version field. You install an update under ECU → Update with “Upload FW”. eBOXes from e-leiwand already have at least firmware 2.6.

How do I back up my settings?

Under System → Configuration, you can download all settings as a text file. This is recommended before updates and major changes.

How do I reset the eBOX?

Under System → Reset with “APP Reset”. Afterwards everything has to be set up again – so back up your settings first.

May the eBOX be installed in Austria?

We explain which requirements apply to wallboxes at the grid connection in OVE R 37 explained.
