I don't know how to acquire the ApplicationID when using mqtt

ChirpStack Application Server

Log into your chirpstack web-interface at http://blah:8080 and navigate to any of your devices. Then, look at the ADDRESS line of your browser, just after “applications/”.

For me, using Opera, that’s:
http://10.1.6.90:8080/#/organizations/1/applications/5/devices/0025ca0a000001e9

Your number will depend on how many times you’ve clicked “CREATE” in Application page.

I didn’t find this very intuitive either - that’s saying something as I grew up on and still use vi as editor of choice :slight_smile: See my other ‘discoveries’ on this very topic HERE.
