+Before you can use the IHC Sensor platform, you must setup the [IHC Component](/components/ihc/)
+
+When auto setup is enabled the following products will be found in the IHC project and setup as sensors:
+
+* Dataline temperature sensor - Will insert 2 temperature sensors
+* Dataline Humidity - Will insert 1 humidity and 2 temperature sensors (calculated dewpoint)
+* Dataline Lux - will insert 1 light and 1 temperature sensor
+
+To manually configure IHC sensors insert this section:
+
+```yaml
+sensor:
+  - platform: ihc
+    sensors:
+      - id: 12345
+        name: 'mysensor'
+        unit_of_measurement: '°C'
+      - id: 12346
+        ...
+```
+
+{% configuration %}
+sensors:
+  description: List of sensors to setup manually
+  required: false
+  type: map
+  keys:
+    id:
+      description: The IHC resource id.
+      required: true
+      type: int
+    name:
+      description: The name of the component
+      required: false
+      type: string
+    unit_of_measurement:
+      description: Defines the unit of measurement of the sensor, if any.
+      required: false
+      type: string
+{% endconfiguration %}
+
+The resource id should be a IHC float resource.
+For more information about IHC resource ids see [Manual Setup](/components/ihc/#manual-setup)
