+
+The Möhlenhoff Alpha 2 integration allows you to control a
+[Möhlenhoff Alpha 2](https://www.moehlenhoff.de/en/products/room-by-room-control/oem-alpha-2-system)
+temperature control system.
+
+## Prerequisites
+
+Please make sure the base station is turned on and connected to your local network.
+
+
+{% include integrations/config_flow.md %}
+
+## Climate
+
+The  climate platform provides current and target temperature information,
+HVAC and preset mode.
+
+A climate entity will be created for each area. The name of the entity is
+taken from the name of the heat area defined in the Alpha 2 base station.
+
+The state is polled from the base every 60 seconds.
+
+Please note that after changing the temperature in Home Assistant,
+it may take up to 10 minutes for your room control units to display these
+changes.
+
