Web UI

Ideas

• Webui will be a service, not rolled into the Casa codebase automatically.
• When a service starts, it could publish a text/template to some topic that the webui service will use when displaying content relevant to that service.
  • This allows the various services to control what information is displayed and how. This should prevent the webui from being out-of-date because as the services are updated so are their webui sections.
