-To get your KNX switches working with Home Assistant, follow the instructions for the [KNX component](/components/knx/).
+
+The KNX switch component is used as in interface to switching actuators.
+
+```yaml
+switch:
+  platform: knx
+  name: KNX Switch
+  address: 0/0/1
+  state_address: 0/0/3
+```
+
+- **name** (*Optional*): A name for this devices used within Home assistant
+- **address** (*Required*): The KNX group address that is used to turn on/off this actuator channel
+- **state_address** (*Optional*): Some KNX devices can change their state internally without any messages on the KXN 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 wil 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 configrue the state address

+The KNX thermostat component is used as in interface with KNX thermostats.
+
+KNX thermostats use at least 2 group addresses: one for the current temperature and one for the target temperature (named set-point in KNX terms).
+
+```yaml
+thermostat:
+  platform: knx
+  name: KNX Thermostat
+  temperature_address: 0/1/1
+  setpoint_address: 0/1/0
+```
+
+- **name** (*Optional*): A name for this devices used within Home assistant
+- **address** (*Required*): The KNX group address that is used to turn on/off this actuator channel
+- **temperature_address** (*Required*): The group address that is used to communicate the current temperature. Data format must be datapoint type 9.001 DPT_Value_Temp (2-Octet float value) (see http://www.knx.org/fileadmin/template/documents/downloads_support_menu/KNX_tutor_seminar_page/Advanced_documentation/05_Interworking_E1209.pdf)
+- **setpoint_address** (*Required*): The group address that is used to set/read the target temperature. Data format must be datapoint type 9.001 DPT_Value_Temp (2-Octet float value). Make sure, you set the read-flag for the thermostat to allow Home Assistant to read the target temperature.
+
+With the current version of the module, no advanced KNX thermostat functionalities (e.g. HVAC mode) are supported.
