I've written a very simple MacOS/iOS app to allow management of the User PINs for the lock on my AirBnB using the RESTful interface of Indigo and this Plugin. Having the PIN read from a variable I could set through the REST interface was essential, thanks for adding that earlier. To make it fully generalized it would be nice if the user field in the plugin was the same, so I chance a few lines of the python and xml files accordingly and it works great. It would be nice if became part of the release so I though I'd post this here. Not much of a git user but let me know if I can help, if you want to do this for the few lines of code.
