Quick question to the ones, that developed already apps around zwave-me:
Are there basically a certain number of default variables accessible within a app e.g. specially a code-app?

e.g. If I want to generate a SMS or E-Mail (e.g. by using a URL-call via code device app) I would like to pass over some more dynamic informations e.g. Device-Names that generated/triggered the alert or other things...

How would this be easily possible without having to write a new dedicated app?

Ideas?

You can store things in the metrics for the device. e.g. if you create a code device with a toggle button you could store something like so:

Thanks, but I was also wondering if there are default variable/objects I can access from any app/device without "saving/storing" first. Bascially I want to do the opposite. Simply use possibly existing informations to use them within different modules dynamically...

Yes, there's a lot you can access. There are links to documentation at the bottom of the Github repo.

I suggest you browse around the API docs to get a feel for what's available, it's trivial to get JSON dumps of the internal state of devices, modules, notifications etc. that way.

If you want to access things with JS from a code device or module have a look at the module developer documentation and maybe browse the code of some of the existing modules to get an idea of the syntax for accessing devices, events etc.
