This is just a head’s up to all:
Vera released a firmware update over the weekend: 1.7.481.
Up until this point, if you did not have a JSON file distributed with your plugin (or if your json was invalid), some of the default tabs (including “Advanced”) would automatically be made available.
After the update, the tabs are still there, but if you expand them, they are blank. So it appears that if you want users to have access to those default tabs, you’ll need to provide a json that explicitly provides access to them.
