Hi Erwin, > For Fibaro, the debug-feature could probably be built as a plugin or virtual device. Docs on both subjects, however, are nowhere to be found on the web. I could try to ask the fibaro support guys if they have any. Thank you for the additional information. It would be good to have access to the plugin docs (if they exist in some form). At the very minimum it would be interesting to see if it's possible to execute a Lua fragment remotely (for example, through http); Vera devices support this through http requests that can take lu_action and runlua parameters. I'm in contact with Fibaro, but don't expect any update until early next week. Paul.
