 This Repository contains a Home Assistant Addon to run Ism7MQTT for reading data from Wolf heaters, equipped with an ISM7 Module, directly.
 
-Please refer to <https://github.com/zivillian/ism7mqtt> for more information, especially for creation of the parameters.json file required to run this.
+Also supports running multiple instances of ism7mqtt. To do so, configure the first instance normally, then, for each ISM7 you have, specify a block like this under "additional ISM7 devices":
+```
+- device_name: "WolfHeizung2
+  ism7_ip: "192.168.x.y"
+  ism7_password: "something"
+  interval: 60
+```
+
+Note that each ISM7 needs a distinct device name without spaces or special characters.
+
