KEBA Wallbox + Display - MAHO LABS
The package integrates a KEBA KeContact P30 or P40 wallbox into the Gira X1 logic directly via Modbus TCP – with no cloud service and no manufacturer account. The wallbox node reads the charging state, currents and voltages per phase, power, power factor and both total and session energy, and it can set the charging current and enable or block charging. This makes PV surplus charging, load limiting and dashboard displays straightforward to implement.
The second node in the package shows any text on the wallbox display – a greeting, a "charging complete" message or the current PV surplus. Both nodes share a single licence. On the wallbox side, DIP switch DSW1.3 must be on, the unit must be on the same LAN and the device ID must be 255.
Key features
• Complete measured values: plain-text charging state, current and voltage per phase, power, power factor, total and session energy, cable status and error code.
• Active control: charging current continuously adjustable from 6 to 63 A, with a dedicated input to enable or block the charging process.
• Shared register map for P30 and P40 – one node covers both series.
• Robust connection handling on demand (connect, read or write, disconnect) with a plain-text diagnostics output.
• Display node with adjustable minimum and maximum display duration; the text is sent automatically whenever it changes.
• Automatic limiting of invalid setpoints: values below 6 A are raised, values above 63 A are capped.
