I'm afraid there's not a Meraki Community app. The reference you found for "device ID" isn't relevant for us, sadly! Some communities powered by Lithium (our platform provider) have used the Lithium API to integrate into other mobile apps, and I believe that's what the "device ID" reference is about - but we haven't done that (maybe someday!).
Cheers! - Caroline
