Compleo eBOX
Monitors and controls Compleo eBOX EV chargers via Modbus TCP
Modbus TCP template for Compleo eBOX EV chargers, compatible with the eBOX smart, professional and touch models. Reads charging currents, energy meter values, cable state, OCPP state and availability. Also allows write control of max current limits, fallback currents, phase setup and availability.

If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Monitor per-phase charging current and energy consumption of Compleo eBOX chargers on a live dashboard.
- Set maximum current limits remotely to implement dynamic load management across multiple charging points.
- Create an alert when the cable state changes unexpectedly or the charger becomes unavailable.
- Track cumulative energy meter readings for billing or tenant energy accounting purposes.
- Adjust fallback current settings from the cloud to ensure safe operation during communication loss.
- Schedule availability changes for eBOX chargers in semi-public or workplace charging scenarios.
Installation
Connect the ModbusCloud Gateway to the same local IP network as the Compleo eBOX charger.
Verify the IP address of the eBOX in its configuration menu and ensure Modbus TCP is enabled.
Import the Compleo eBOX template from the ModbusCloud template library into your project.
Enter the eBOX IP address and Modbus TCP port (typically 502) in the gateway configuration.
Confirm the eBOX firmware is version 2.1.0 or later if you need voltage and energy meter registers (IDs 13 to 16).
Check that readings appear in the ModbusCloud dashboard and verify a test write to the Max Current register.
Things to watch for
Why are the voltage and energy meter registers returning zero or invalid values?
These registers (IDs 13 to 16) require Compleo eBOX firmware version 2.1.0 or later. Update the charger firmware through the Compleo service portal if you are running an older version.
What data format do the registers use?
The template uses float32 values that span two consecutive Modbus addresses. The byte order and register pairing are preconfigured in the template, so no manual adjustment is needed.
Do I need RS-485 wiring for this template?
No. The Compleo eBOX communicates over Modbus TCP, so only an Ethernet or Wi-Fi network connection between the gateway and the charger is required.
Can I control multiple eBOX chargers with one gateway?
Yes. Add a separate device instance for each charger in the ModbusCloud project, each with its own IP address. The gateway communicates with all of them over the local network.
