When you have a usage relationship with a resource, you can interact with it.
You can remote control a resource by using its control panel to send supported command requests and check sensor readings. Use the resource page for the full resource-wide panel; use your home page for compact cards from the current dashboard. Learn more about the remote control of resources.
You can access a resource by clicking on its image. If the resource is connected with a link to a service, the image shown in the page of the resource and in your home page will point to that service. Learn more about the resource access.
