Hi,

I have a strange situation in a flow on my Homey.  
I cannot not understand why some variables are not set.

So i was wondering: Is there a way to ‘trace’ what Homey is doing in a certain flow ?  
(following Homey card by card).

Peter

You can click on the test button and see what happens card by card. Not what you asked but it is a way to follow card by card if your AND or THAN cards are ok. Every card gets a ✅ or ❌

You can use this App for logging a Flow: [PaperTrails Logbuch App für Homey | Homey](https://homey.app/de-ch/app/nu.dijker.papertrails/PaperTrails-Logbuch/)
