Please add a switch for 1-phase charging #71

Open DenBir opened 11 months ago

DenBir commented 11 months ago

The Power Brain Wallbox Solar use as default 3-phase charging and with a switch in the UI you can set to 1-phase charging. It would be great if you add this switch in your HA Power Brain integration.

Thanks, Dennis

Hi, unfortunately I do not own a powerbrain wallbox with the phase switching feature and have no possibility to develop and test it. If anyone wants to contribute, please feel free.

Hi @mb-software ,

I have a WB with phase switching (with the provided upgrade kit) but no knowlegde for Python.

Of course, I can provide you with the necessary information and then be happy to test it.

I found on the homepage the following guide https://www.cfos-emobility.de/en/cfos-charging-manager/documentation/automatic-phase-switching.htm

Set up an RFID for 3-phase charging in the user settings and set "Method" as the Charging Manager Output: GET and "URL" for this card: http://localhost/cnf?cmd=modbus&device=evse&write=8087&value=0 For single-phase charging, you can set up an RFID card with Charging Manager Output "Method": GET and as "URL": http://localhost/cnf?cmd=modbus&device=evse&write=8087&value=1 The prerequisite is that the wallbox runs as a master with activated load management.

and here the the necessary register 8087 https://www.cfos-emobility.de/en/cfos-power-brain/modbus-registers.htm
