+
+The Hisense AEH-W4A1 is a WiFi module used to give WiFi connectivity to some Hisense ACs and rebranded models (Smart Cool, Beko and others).
+
+Later AC models use other WiFi modules (like AEH-W4B1 and AEH-W4E1) that are not compatible or otherwise tested with this integration.
+
+It is highly recommended not to use one of the official smartphone applications and this integration at the same time, to avoid problems related to command collision.
+
+## Configuration
+
+To integrate one or more Hisense AEH-W4A1 controlled ACs with Home Assistant, use the Configuration/Integrations or add the following section to your `configuration.yaml` file:
+
+```yaml
+# Automatic discovery
+hisense_aehw4a1:
+```
+
+Alternately, devices that are not discoverable can be statically configured.
+The use of static configuration disables automatic discovery.
+
+{% configuration %}
+ip_address:
+  description: One or more static IP addresses
+  required: false
+  type: list
+{% endconfiguration %}
+
+## Full configuration example
+
+```yaml
+# Static configured devices
+hisense_aehw4a1:
+  ip_address:
+  - 192.168.5.10
+  - 192.168.5.20
+```
