The [KNX](https://www.knx.org) integration for Home Assistant allows you to connect to KNX/IP devices.
The integration requires a local KNX/IP interface or router. Through this, it will establish a connection between Home Assistant and your KNX bus.
Please note, the `knx` platform does not support KNX Secure.
There is currently support for the following device types within Home Assistant:
- [Binary Sensor](#binary-sensor)
- [Climate](#climate)
- [Cover](#cover)
- [Light](#light)
- [Notify](#notify)
- [Scene](#scene)
- [Sensor](#sensor)
- [Switch](#switch)
- [Weather](#weather)
## Basic Configuration
To use your KNX bus in your installation, add the following lines to your `configuration.yaml` file:
```yaml
knx:
```
In order to make use of the various platforms KNX offers you will need to have the following configuration inside `configuration.yaml` depending on what
platforms you intend to use:
```yaml
knx:
binary_sensor: !include knx_binary_sensor.yaml
switch: !include knx_switch.yaml
sensor: !include knx_sensor.yaml
cover: !include knx_cover.yaml
light: !include knx_light.yaml
notify: !include knx_notify.yaml
scene: !include knx_scene.yaml
```
Please check the dedicated platform documentation about how to configure them correctly.
Optional, or if you want to use the XKNX abstraction also for other scripted tools outside of Home Assistant:
```yaml
knx:
config_file: '/path/to/xknx.yaml'
```
{% configuration %}
config_file:
description: The path for XKNX configuration file. See [xknx.io](https://xknx.io/configuration) for details
required: false
type: string
rate_limit:
description: Defines the maximum number of telegrams to be sent to the bus per second (range 1-100).
required: false
default: 20
type: integer
individual_address:

{% endconfiguration %}
## Services
In order to directly interact with the KNX bus, you can use the following service:
```txt
Domain: knx
Service: send
Service Data: {"address": "1/0/15", "payload": 0, "type": "temperature"}
```
{% configuration %}
address:
description: KNX group address
type: string
payload:
description: Payload to send to the bus. When `type` is not set, raw bytes are sent. Integers are then treated as DPT 1/2/3 payloads. For DPTs > 6 bits send a list. Each value represents 1 octet (0-255). Pad with 0 to DPT byte length.
type: [integer, list]
type:
description: If set, the payload will not be sent as raw bytes, but encoded as given DPT. KNX sensor types are valid values - see table in [KNX Sensor](#sensor).
type: [string, integer, float]
{% endconfiguration %}
You can also use the `homeassistant.update_entity` service call to issue GroupValueRead requests for all `*state_address` of a device.
## Exposing entity states, entity attributes or time to KNX bus
KNX integration is able to expose entity states or attributes to KNX bus. The integration will broadcast any change of the exposed value to the KNX bus and answer read requests to the specified group address. It is also possible to expose the current time.
```yaml
# Example configuration.yaml entry
knx:
expose:
- type: 'temperature'
entity_id: 'sensor.owm_temperature'
address: '0/0/2'
- type: 'string'
address: '0/6/4'
entity_id: "sensor.owm_weather"
- type: 'binary'
entity_id: 'binary_sensor.kitchen_window'
address: '0/6/5'
- type: 'binary'
entity_id: 'light.office'
address: '0/3/0'
default: False
- type: 'percentU8'
entity_id: 'light.office'
attribute: 'brightness'
default: 0
address: '0/3/1'
- type: 'time'
address: '0/0/1'
- type: 'datetime'
address: '0/0/23'
```
{% configuration %}
type:
description: Type of the exposed value. Either 'binary', 'time', 'date', 'datetime' or any supported type of [KNX Sensor](#sensor) (e.g., "temperature" or "humidity").
type: string
required: true
entity_id:
description: Entity id to be exposed. Not needed for types time, date and datetime.
type: string
required: false
attribute:
description: Attribute of the entity that shall be sent to the KNX bus. If not set (or `None`) the state will be sent.
Eg. for a light the state is eigther "on" or "off" - with attribute you can expose its "brightness".
type: string
required: false
default:
description: Default value to send to the bus if the state or attribute value is `None`.
Eg. a light with state "off" has no brightness attribute so a default value of `0` could be used.
If not set (or `None`) no value would be sent to the bus and a GroupReadRequest to the address would return the last known value.
type: [boolean, string, integer, float]
default: None
required: false
address:
description: KNX group address.
type: string
required: true
{% endconfiguration %}
The `knx` sensor platform allows you to monitor [KNX](https://www.knx.org/) binary sensors.
Binary sensors are read-only. To write to the knx-bus configure an exposure [KNX Integration - Expose](/integrations/knx/#exposing-sensor-values-or-time-to-knx-bus).
## Binary Sensor
To use your binary sensors please add the relevant configuration to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
knx:
binary_sensor:
- name: sensor1
state_address: '6/0/2'
```
{% configuration %}
state_address:
description: KNX group address of the binary sensor. *DPT 1*
required: true
type: string
name:
description: A name for this device used within Home Assistant.
required: false
type: string
sync_state:
description: Actively read the value from the bus. If `False` no GroupValueRead telegrams will be sent to the bus. `sync_state` can be set to `init` to just initialize state on startup, `expire ` to read the state from the KNX bus when no telegram was received for \ or `every ` to update it regularly every \. Maximum value for \ is 1440. If just a number is configured "expire"-behaviour is used. Defaults to `True` which is interpreted as "expire 60".
required: false
type: [boolean, string, integer]
default: True
device_class:
description: Sets the [class of the device](/integrations/binary_sensor/), changing the device state and icon that is displayed on the frontend.
required: false
type: string
reset_after:
description: Reset back to OFF state after specified seconds.
required: false
type: float
invert:
description: Invert the telegrams payload before processing. This is applied before `context_timeout` or `reset_after` is evaluated.
required: false
type: boolean
default: False
ignore_internal_state:
description: Specifies if telegrams should ignore the internal state and always trigger a Home Assistant state update.
required: false
type: boolean
default: False
context_timeout:
description: The time in seconds between multiple identical telegram payloads would count towards the internal counter that is used for automations. Ex. You have automations in place that trigger your lights on button press and another set of lights if you click that button twice. This setting defines the time that a second button press would count toward, so if you set this 3.0 you can take up to 3 seconds in order to trigger the second button press. If set `ignore_internal_state` will be set to `True` internally. Maximum value is 10.0.
required: false
type: float
default: None
{% endconfiguration %}
### Support for automations
You can use a built in event in order to trigger an automation (e.g. to switch on a light when a switch was pressed).
Let's pretend you have a binary sensor with the name `Livingroom.Switch` and you want to switch one light on when the button was pressed once and two other lights when the button was pressed twice.
```yaml
# Example automation.yaml entry
automation:
- trigger:
platform: numeric_state
entity_id: binary_sensor.Livingroom_Switch
attribute: counter
above: 0
below: 2
condition:
- condition: state
entity_id: binary_sensor.cover_abstell
state: 'on'
action:
- entity_id: light.hue_color_lamp_1
service: light.turn_on
- trigger:
platform: numeric_state
entity_id: binary_sensor.Livingroom_Switch
attribute: counter
above: 1
below: 3
condition:
- condition: state
entity_id: binary_sensor.cover_abstell
state: 'on'
action:
- entity_id: light.hue_bloom_1
service: homeassistant.turn_on
- entity_id: light.hue_bloom_2
service: homeassistant.turn_on
```
{% configuration %}
name:
description: A name for this device used within Home Assistant.
required: false
type: string
counter:
description: Set to 2 if your only want the action to be executed if the button was pressed twice. To 3 for three times button pressed.
required: false
type: integer
default: 1
hook:
description: Indicates if the automation should be executed on what state of the binary sensor. Values are "on" or "off".
required: false
type: string
default: "on"
action:
description: Specify a list of actions analog to the [automation rules](/docs/automation/action/).
required: false
type: list
{% endconfiguration %}
## Climate
The `knx` climate platform is used as an interface to KNX thermostats and room controllers.
To use your KNX thermostats in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
# Example configuration.yaml entry
knx:
climate:
- name: HASS-Kitchen.Temperature
temperature_address: '5/1/1'
setpoint_shift_address: '5/1/2'
setpoint_shift_state_address: '5/1/3'
target_temperature_state_address: '5/1/4'
operation_mode_address: '5/1/5'
operation_mode_state_address: '5/1/6'
```
Alternatively, if your device has dedicated binary group addresses for frost/night/comfort mode:
```yaml
# Example configuration.yaml entry
knx:
climate:
- name: HASS-Kitchen.Temperature
temperature_address: '5/1/1'
setpoint_shift_address: '5/1/2'
setpoint_shift_state_address: '5/1/3'
target_temperature_state_address: '5/1/4'
operation_mode_frost_protection_address: '5/1/5'
operation_mode_night_address: '5/1/6'
operation_mode_comfort_address: '5/1/7'
operation_mode_state_address: '5/1/8'
```
If your device doesn't support setpoint_shift calculations (i.e., if you don't provide a `setpoint_shift_address` value) please set the `min_temp` and `max_temp`
attributes of the climate device to avoid issues with exceeding valid temperature values in the frontend. Please do also make sure to add the `target_temperature_address`
to the configuration in this case.:
```yaml
# Example configuration.yaml entry
knx:
climate:
- name: HASS-Kitchen.Temperature
temperature_address: '5/1/2'
target_temperature_address: '5/1/4'
target_temperature_state_address: '5/1/1'
operation_mode_frost_protection_address: '5/1/5'
operation_mode_night_address: '5/1/6'
operation_mode_comfort_address: '5/1/7'
operation_mode_state_address: '5/1/8'
operation_mode_standby_address: '5/1/9'
min_temp: 7.0
max_temp: 32.0
```
`setpoint_shift_mode` allows the two following DPTs to be used:
- DPT6002 (for 1 byte signed integer)
- DPT9002 (for 2 byte float)
Example:
```yaml
# Example configuration.yaml entry
knx:
climate:
- name: HASS-Kitchen.Temperature
temperature_address: '5/1/1'
setpoint_shift_address: '5/1/2'
setpoint_shift_state_address: '5/1/3'
setpoint_shift_mode: 'DPT9002'
target_temperature_state_address: '5/1/4'
operation_mode_address: '5/1/5'
operation_mode_state_address: '5/1/6'
```
`operation_mode_frost_protection_address` / `operation_mode_night_address` / `operation_mode_comfort_address` / `operation_mode_standby_address` are not necessary if `operation_mode_address` is specified.
If the actor doesn't support explicit state communication objects the *_state_address can be configured with the same group address as the writeable *_address. The Read-Flag for the *_state_address communication object has to be set in ETS to support initial reading e.g., when starting Home Assistant.
The following values are valid for the `heat_cool_address` and the `heat_cool_state_address`:
- 0 (cooling)
- 1 (heating)
The following values are valid for the `hvac_mode` attribute:
- Off (maps internally to HVAC_MODE_OFF within Home Assistant)
- Auto (maps internally to HVAC_MODE_AUTO within Home Assistant)
- Heat (maps internally to HVAC_MDOE_HEAT within Home Assistant)
- Cool (maps internally to HVAC_MDOE_COOL within Home Assistant)
- Fan only (maps internally to HVAC_MODE_FAN_ONLY within Home Assistant)
- Dry (maps internally to HVAC_MODE_DRY within Home Assistant)
The following presets are valid for the `preset_mode` attribute:
- Auto (maps internally to PRESET_NONE within Home Assistant)
- Comfort (maps internally to PRESET_COMFORT within Home Assistant)
- Standby (maps internally to PRESET_AWAY within Home Assistant)
- Night (maps internally to PRESET_SLEEP within Home Assistant)
- Frost Protection (maps internally to PRESET_ECO within Home Assistant)

{% endconfiguration %}
Many KNX devices can change their state internally without a message to the switch address on the KNX bus, e.g., if you configure a scene or a timer on a channel. The optional `state_address` can be used to inform Home Assistant about these state changes. If a KNX message is seen on the bus addressed to the given `state_address` (in most cases from the light actuator), it will overwrite the state of the switch object.
For switching/light actuators that are only controlled by a single group address and don't have dedicated state communication objects you can set `state_address` to the same value as `address`.
*Note on tunable white:* Home Assistant uses Mireds as the unit for color temperature, whereas KNX typically uses Kelvin. The Kelvin/Mireds relationship is reciprocal, not linear, therefore the color temperature pickers (sliders) in Home Assistant may not align with ones of KNX visualizations. This is the expected behavior.

```
## Notify
The `knx` notify platform allows you to send notifications to [KNX](https://www.knx.org/) devices.
### Configuration
To use your KNX switch in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
knx:
notify:
- name: Alarm
address: '5/1/10'
```
{% configuration %}
address:
description: KNX group address of the notification. *DPT 16.000*
required: true
type: string
name:
description: A name for this device used within Home Assistant.
required: false
type: string
{% endconfiguration %}
The `knx` scenes platform allows you to trigger [KNX](https://www.knx.org/) scenes.
## Scene
### Configuration
To use your KNX scene in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
# Example configuration.yaml entry
knx:
scene:
- name: Romantic
address: 8/8/8
scene_number: 23
```
{% configuration %}
address:
description: KNX group address for the scene. *DPT 17.001*
required: true
type: string
scene_number:
description: KNX scene number to be activated. ( 1 ... 64 )
required: true
type: integer
name:
description: A name for this device used within Home Assistant.
required: false
type: string
{% endconfiguration %}
## Sensor
The `knx` sensor platform allows you to monitor [KNX](https://www.knx.org/) sensors.
Sensors are read-only. To write to the knx-bus configure an exposure [KNX Integration - Expose](/integrations/knx/#exposing-sensor-values-or-time-to-knx-bus).
### Configuration
To use your KNX sensor in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
# Example configuration.yaml entry
knx:
sensor:
- name: Heating.Valve1
state_address: '2/0/0'
```
In order to actively read the sensor data from the bus all 30 minutes you can add the following lines to your `configuration.yaml`:
```yaml
# Example configuration.yaml entry
knx:
sensor:
- name: Heating.Valve1
state_address: '2/0/0'
sync_state: every 30
```
{% configuration %}
state_address:
description: KNX group address of the sensor.
required: true
type: string
name:
description: A name for this device used within Home Assistant.
required: false
type: string
sync_state:
description: Actively read the value from the bus. If `False` no GroupValueRead telegrams will be sent to the bus. `sync_state` can be set to `init` to just initialize state on startup, `expire ` to read the state from the KNX bus when no telegram was received for \ or `every ` to update it regularly every \. Maximum value for \ is 1440. If just a number is configured "expire"-behaviour is used. Defaults to `True` which is interpreted as "expire 60".
required: false
type: [boolean, string, integer]
default: True
type:
description: A type from the following table must be defined. The DPT of the group address should match the expected KNX DPT to be parsed correctly.
required: true
type: string
always_callback:
description: Defines if telegrams with equal payload as the previously received telegram should trigger a state update within Home Assistant.
required: false
type: boolean
default: False

### Full example
```yaml
# Example configuration.yaml entry
knx:
sensor:
- name: Heating.Valve1
state_address: '2/0/0'
sync_state: init
type: 'percent'
- name: Kitchen.Temperature
state_address: '6/2/1'
sync_state: every 60
type: 'temperature'
```
## Switch
The `knx` switch platform is used as an interface to switching actuators.
### Configuration
To use your KNX switch in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
knx:
switch:
- name: Kitchen.Coffee
address: '1/1/6'
```
{% configuration %}
address:
description: KNX group address for switching the switch on/off. *DPT 1*
required: true
type: string
name:
description: A name for this device used within Home Assistant.
required: false
default: KNX Switch
type: string
state_address:
description: Separate KNX group address for retrieving the switch state. *DPT 1*
required: false
type: string
invert:
description: Invert the telegrams payload before processing or sending.
required: false
type: boolean
default: False
{% endconfiguration %}
Some KNX devices can change their state internally without any messages on the KNX bus, e.g., if you configure a timer on a channel. The optional `state_address` can be used to inform Home Assistant about these state changes. If a KNX message is seen on the bus addressed to the given state address, this will overwrite the state of the switch object.
For switching actuators that are only controlled by a single group address and can't change their state internally, you don't have to configure the state address.
## Weather
The `knx` weather platform is used as an interface to KNX weather stations.
To use your KNX weather station in your installation, add the following lines to your top level [KNX Integration](/integrations/knx) configuration key in `configuration.yaml`:
```yaml
# Example configuration.yaml entry
knx:
