+### Multiple devices
+
+As of 1.2.0 the Hassio addon supports multiple devices by running paralell NodeJS processes in PM2. Old configurations will work, but are deprecated.
+
+Deprecated config example:
+
+```json
+"hvac_host": "192.168.0.255",
+"mqtt": {
+ "broker_url": "mqtt:https://localhost",
+ "topic_prefix": "/my/topic/prefix",
+}
+```
+
+Correct config example:
+
+```json
+"mqtt": {
+ "broker_url": "mqtt:https://localhost",
+},
+"devices": [
+ {
+ "hvac_host": "192.168.0.255",
+ "mqtt_topic_prefix": "/home/hvac01"
+ },
+ {
+ "hvac_host": "192.168.0.254",
+ "mqtt_topic_prefix": "/home/hvac02"
+ }
+]
+```

 ## Configuring HVAC WiFi
 
 1. Make sure your HVAC is running in AP mode. You can reset the WiFi config by pressing MODE +WIFI (or MODE + TURBO) on the AC remote for 5s.
