Raedian NEX AVIA VOLT
Controls and monitors the AVIA VOLT AC Wallbox via Modbus TCP
This template integrates the Raedian NEX AVIA VOLT AC wallbox via Modbus TCP. It reads charging state, voltage, current, power, and energy data while allowing control of charging current limits and session start/stop. Ideal for installers managing EV charging infrastructure remotely.

Use cases
- Monitor real-time charging state, voltage, and current across all three phases on a live dashboard.
- Set dynamic charging current limits remotely to implement load management across multiple wallboxes.
- Create alerts when the charging session stops unexpectedly or when power consumption exceeds a threshold.
- Track energy delivered per session to generate usage reports for billing or cost allocation.
- Start or stop charging sessions remotely from the ModbusCloud platform without on-site access.
- Verify wallbox performance after installation by reviewing phase voltages and current readings.
Installation
Commission the Raedian NEX AVIA VOLT wallbox using the Raedian install app and assign a fixed IP address via LAN or WLAN.
Connect the ModbusCloud Gateway to the same local network as the wallbox.
Verify that the wallbox is reachable on its fixed IP address from the gateway network.
Import the Raedian NEX AVIA VOLT template in the ModbusCloud platform and configure the wallbox IP address and Modbus TCP port.
Confirm that readings such as charging state, voltage, and current appear correctly on the ModbusCloud dashboard.
Set the maximum charging current limit according to your grid capacity and the installed fuse rating for the wallbox.
Things to watch for
The gateway cannot connect to the wallbox over Modbus TCP. What should I check?
Verify that the wallbox has a fixed IP address assigned via the Raedian install app. Ensure the gateway and wallbox are on the same network and that no firewall rules block Modbus TCP traffic on port 502.
I set a charging current value but the session paused instead of charging. Why?
The valid range for Mode 3 charging is 6000 to 32000 (representing 6A to 32A). Values between 0 and 5999 will pause the charging session. Set the value to at least 6000 to resume charging.
Can I use WLAN instead of LAN for the wallbox connection?
Yes, the AVIA VOLT supports both LAN and WLAN. However, a fixed IP address is required regardless of the connection method. A wired LAN connection is generally more reliable for Modbus TCP communication.
What determines the maximum charging current I can set?
The maximum charging current depends on your grid capacity and the fuse rating installed for the wallbox. Do not exceed the rated capacity of your electrical installation.
