You can use the cFos Charging Manager for an unlimited time to read meters (freeware). That means you can use the cFos Charging Manager, including HTTP API, as free software to visualise meters.
During the 90-day trial period, currently until 1.1.1900, you can configure a maximum of 5 EVSEs and control them remotely. This way you can try out whether the cFos Charging Manager works well with a certain type of EVSE. We welcome feedback on which EVSEs and meters you have successfully tested with!
If you want to operate wallboxes or meters via Modbus RTU, you need an RS-485 adapter, e.g. this USB RS485 converter.
This will show up as a COM port on Windows and Raspberry. You must then specify the correct COM port number in the "Address" field of the cFos Charging Manager, e.g. COM3.
For Windows and Raspberry, the cFos Charging Manager for HTTP and HTTPS is installed on ports 4712. You can change this later if necessary.
Here is the list of changes.
