Just in case it helps someone else:
I have tried other pre-cooked KEBA Wallbox integrations but have failed in a setup with multiple wallboxes.
It turned out that using the ModBus integration was actually rather easy and works like a charm for me.
It consists of 3 elements:
- The actual Modus Configuration to read the sensors
- Some template sensors to translate sensor reading e.g. into readable text
- For write-only-registers in the wallboxes you can simply use the build in modbus service calls in your automations.
For reference please see my configuration. You have to copy the sections for each of your wallboxes and just put the IP address in and change name and sensor names accordingly. I show below just one station (I have 2).
I am still waiting for feedback from KEBA on how load balancing works if you write new values into the max charging current registers, but assume for now that those will be just a reduction of the max charging current for an individual callbox and load balancing works within the max current as set via the dip switches in the hardware of the master.

- syntax for writing registers for max charging current, enabling/disabling a station, setting a session target energy for the next loading session.
You have to just take the parts without the # and use it in automations. In my case I have created a helper for the max charging current which then gets written to the wallbox.
# WriteOnly Daten
# in Automationen wie folgt verwenden:
#
# **** maximalen Ladestrom auf den Wert setzen, der in "input_number.wallboxlinks_target_current" steht
# service: modbus.write_register
# data:
# address: 5004
# hub: WallboxLinks
# value: "{{states('input_number.wallboxlinks_target_current')}}". # or put a fixed value here
#
# **** Session Energie setzen
# service: modbus.write_register
# data:
# address: 5010
# hub: WallboxLinks
# value: # put value for session energy here
#
# **** Ladestation sperren oder einschalten (enable/disable)
# service: modbus.write_register
# data:
# address: 5014
# hub: WallboxLinks
# value: "0" # einschalten/enable mit "1"
Enjoy!
