 async def run():
     hub = neohub.NeoHub()
     system = await hub.get_system()
-    hub_data, thermostats = await hub.get_live_data()
-    for device in thermostats:
+    hub_data, devices = await hub.get_live_data()
+    for device in devices['thermostats']:
         print(f"Temperature in zone {device.name}: {device.temperature}")
         await device.identify()
