Recently I updated to v2 and now I’m getting used to the App on my Android phone 🙂

My first question is about the Homey logic variables; I see a bunch of them when I go to “More / Meer” and “Logic / Logica”. Is there a way to find out **where** these variables are used?

Also; what is the fastest way to check the Papertrail log?

Thanks!
