+The **APsystems** {% term integration %} allows you to read the data from your [APsystems EZ1](https://emea.apsystems.com/diy/ez1/) microinverter.
+The following data is provided by the integration:
+
+- Lifetime production (Per input and in total)
+- Current production (Per input and in total)
+- Today's production (Per input and in total)
+
+## Prerequisites
+
+Make sure the local API is activated and set to **Continuously**. For that, connect to the inverter via Bluetooth using the app and go to **Settings** > **Local Mode**, set the switch **Enable Local Mode** to on and make sure to set this to **Continuously**.
