   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.

   POST /cnf?cmd=set_device HTTP/1.1
   Property: allow_ph_sw
   Value: true / false
   Property path: devices[0].allow_ph_sw
   

   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

   For a phase switch you can add the following code to your configuration.yaml:

   command_line:
     - switch:
         name: cfos_phase_switch
         command_on: "curl -s 'http://user:password@192.168.0.0/cnf?cmd=modbus&device=evse&write=8087&value=1'"
         command_off: "curl -s 'http://user_:password@192.168.0.0/cnf?cmd=modbus&device=evse&write=8087&value=0'"
   

   You have to replace user (often admin), password and the IP adress.
   After restart you will find a integration called "Command line" and there the entity "cfos_phase_switch".
   On (=1) is 1-phase and off (=0) is 3-phase.
   Yo can ckeck the state using the following URL: http://192.168.0.0/cnf?cmd=modbus&device=evse&read=8087

   This has been implemented in PR #92.

   A new select entity Phase Mode is added for each EVSE with options 1 phase and 3 phases. It uses Modbus register 8044 (used_phases bitfield: 1=L1 only, 7=L1+L2+L3).

   There is also a new service powerbrain.set_phase_mode for use in automations:

   service: powerbrain.set_phase_mode
   data:
     dev_id: E1
     phases: 1
