Hi Steve,
In terms of instructions, it sounds as though you would benefit from watching a couple of the key VC video tutorials to help you understand some of the fundamentals of how to use VC and xml you find on the forum etc., as it will save you a lot of time and headache in the long run.
First, an important tip is that you should not need to save xml you find in a code box on the forum to a file and then import it. You can actually just select that text, and
copy and paste it directly into your command tree.
Also, not all xml posted as message *attachments* are commands. Often these attachments are payload xml files that are used with a posted command. This should be evident from the context of the post.
Second, it will be important for your Fibaro needs to learn about how payloads work, and how to construct/edit commands in general.
For a quick start to learn about commands similar to what you want to do with the Fibaro, I recommend you watch the
Vera video tutorial. The concepts discussed there will be generally applicable to the Fibaro, except that you'll be using the Scrape action instead of the Vera actions.
It's also important for all new users to watch at least the first
Editing & Building Commands tutorial, though watching both of the "Editing Commands" tutorials will go a long way.
http://voxcommando.com/mediawiki/index.php?title=Video_TutorialsYou will ideally want to create a payload XML file that contains the IDs for your different dimmable lights associated with whatever phrase you want to use for each (25 --> living room light).
You will understand how this works much better by watching the Vera video.
However, you can start by directly copying and pasting the command URL you mention above into the Scrape commmand and hitting "save and execute". That should test whether the command effectively dims or brightens your light with ID 25 to 50% brightness.
As a starting point, I've attached an annotated image of the command I posted as well.
