integration |
The keba integrates your Keba charging station/BMW Wallbox into your Home Assistant instance using the UDP Smart Home Interface (manual). The fetching interval to the charging station is set to 5 seconds, same as in the official mobile app. In order to use the integration, enable the UDP Smart Home Interface by adjusting the DIP switches within the charging station according to the installation manual.
This component provides the following platforms:
- Binary Sensors: Online state, plug state, Charging state and failsafe mode state.
- Lock: Authorization (like with the RFID card).
- Sensors: current set by the user, target energy set by the user, charging power, charged energy of the current session and total energy charged.
- Services: authorize, deauthorize, set energy target, set the maximum allowed current and manually update the states. More details can be found here.
- Notify: Show a text on chargers with a built-in LED display.
Configuration
To enable this component in your installation, add at least the following to your configuration.yaml file:
# Example configuration.yaml entry
keba:
host: KEBA_HOST
{% configuration %}
keba:
description: configuration
required: true
type: map
keys:
host:
description: Keba host.
required: true
type: string
rfid:
description: RFID tag used for authorization.
required: false
type: string
default: "00845500"
failsafe:
description: Enable failsafe mode at Home Assistant startup.
required: false
type: boolean
default: false
failsafe_timeout:
description: Timeout of the failsafe mode in seconds. Allowed values are between 10 seconds and 600 seconds (this parameter is only used if failsafe mode is enabled). Make sure to call the keba.set_curr service regularly within this timeout period!
required: false
type: integer
default: 30
failsafe_fallback:
description: Fallback current of the failsafe mode in A. Allowed values are between 6 Ampere and 63 Ampere. 0 Ampere disables the running charging process completely (this parameter is only used if failsafe mode is enabled).
required: false
type: integer
default: 6
failsafe_persist:
description: Saving the failsafe configuration to internal EEPROM of the Keba charging station. 1 means save it, 0 means do only keep this configuration until the next restart of the charging station (this parameter is only used if failsafe mode is enabled).
required: false
type: integer
default: 0
refresh_interval:
description: Refresh interval to fetch new data from the charging station. 5 seconds (same as in the official app) is recommended.
required: false
type: integer
default: 5
{% endconfiguration %}
Services
The keba component offers several services. Using these services will change the state of your charging station. So use these services with care!
Authorizing and Deauthorizing keba.authorize and keba.deauthorize
The charging station can be authorized and deauthorized via service calls (keba.authorize and keba.deauthorize) or via the lock component that is created automatically for the charging station. In both cases the RFID tag from the configuration is used.
Start and Stop keba.start and keba.stop
The service keba.start and keba.stop controls the charging process if the car is already authorized. Technically it sends ena 1 or ena 0 commands to the charging station.
Set Target Energy keba.set_energy
The service keba.set_energy sets the target energy for the current session to the given energy attribute in kWh. Payload example:
{
"energy": 10.0
}
Maximum Current keba.set_curr
The service keba.set_curr sets the maximum current to the given current attribute in Ampere. Payload example:
{
"current": 16.0
}
Request New Data keba.request_data
The service keba.request_data sends data update requests to the charging station.
Request New Data keba.set_failsafe
The service keba.set_failsafe sets the failsafe mode of the charging station. Payload example:
{
"failsafe_timeout": 30,
"failsafe_fallback": 6,
"failsafe_persist": 0
}
Notifications
Some Keba chargers are equipped with a LED text display. The notification platform may be used to display text on this display. To enable this, add the following to your configuration.yaml file:
Configuration
# Example configuration.yaml entry
notify:
- name: NOTIFIER_NAME
platform: keba
{% configuration %}
name:
description: Setting the optional parameter name allows multiple notifiers to be created. The notifier will bind to the service notify.NOTIFIER_NAME.
required: false
default: "notify"
type: string
{% endconfiguration %}
Usage
The use of the notify service is described here.
The message part of the event payload is shown on the display. Scrolling is performed if needed. A maximum of 23 characters can be shown.
The optional data part may contain specifications of the message duration. min_time is the minimum time in seconds the text will be shown if another message is requested. max_time is the maximum time to display the message when nothing else is requested. By default, the message is shown a minimum of 2 seconds and a maximum of 10 seconds.
message: "Welcome home"
data:
min_time: 4
max_time: 10
