Once you have added the Cosy skill to your Alexa account, you'll need to link your Cosy system so that Alexa can control it.

To do this, simply click the 'link skill' button from the Cosy skill page, you'll be taken to a login page where you'll need to enter the credentials that you use to sign into the Cosy app. After a few moments, the page will confirm that your Cosy system has been successfully linked with your Alexa account.
