go-e Charger - MAHO LABS
The building block integrates a go-e Charger (Gemini, HOME+, or HOMEfix) directly with the Gira X1 or L1, enabling monitoring, control, and automatic switching between single-phase and three-phase charging. It provides access to charging status, currents and voltages on phases L1-L3, charging power, session energy, total energy consumption, and the currently available grid phases.
Charging current (6-32 A) and charging authorization can be controlled directly via KNX group addresses or from logic functions. For PV surplus charging, the integrated phase-switching automation automatically changes between single-phase and three-phase operation based on the available surplus power. Hysteresis and a minimum switching interval prevent frequent switching and ensure stable operation.
Requirements: Modbus interface enabled in the go-e app (Internet → Advanced Settings → Modbus), firmware version 55.6 or later, and a charger with a fixed IP address on the same network as the Gira X1.
Key Features:
Monitoring of vehicle status, error codes, currents and voltages (L1-L3), charging power, and energy values
Control of charging current from 6 to 32 A, including charging enable/disable
Automatic phase switching between single-phase and three-phase charging based on PV surplus, using two configurable thresholds (hysteresis)
Minimum switching interval of 5 minutes between phase changes
Optional smooth switching: charging is briefly paused before a phase change and automatically resumed afterward
Clear-text phase status information (e.g., "Wallbox operating in 3-phase mode, vehicle charging in 1-phase mode") and dedicated diagnostic
outputs for troubleshooting and monitoring.
