🔌🚗 QA Wallbox ABL eMH1 EMS Modbus ASCII
QA Wallbox ABL eMH1 is an application for communication and control of the ABL eMH1 wallbox. It enables reading operating and status values and direct manual control of charging modes and power.
The application can be used standalone as a monitoring and control interface, or integrated as part of home energy management. The application itself does not contain automation logic, but serves as a data and control interface for superior applications.
💼 Business Presentation
The application provides an overview of charging status and wallbox operating values and allows its manual control. In standalone operation, it serves as a monitoring and control interface.
For automatic charging control based on photovoltaic surplus, an extension with the QA Consumption Control application is required.
For spot-rate charging control, a combination of QA Spot PRO and QA Wallbox Control applications is required.
The QA ABL eMH1 Integration application itself does not control charging automatically, but provides communication, data collection and direct wallbox control for superior control systems.
📊 Analysis and Data Processing
For clear visualization, work with measurement history and graphs, we recommend connecting to SCADA Mervis.
