 ## How you can use this integration
 
-The IronOS integration lets you monitor and control your smart soldering iron from Home Assistant and automate related tasks. For example, you can turn on a fume extractor automatically when the soldering iron enters soldering mode, and turn it off when the iron is laid down. You can also monitor the temperature of the tip and handle, as well as power draw and input voltage, directly in dashboards.
