When deleting a device, flows get a triangle with exclamation mark in it indicating that they are still using a non-existing device and won’t work anymore. However when deleting a variable, flows do not get any indication that it is using a non-existing variable, instead the flow card just gets an empty field. So when deleting a variable, it seems that there is no other way then just opening all the flows and checking the flow cards for empty fields. Or does somebody else have a smart idea how to check, whether flows are using non-existing variables? ---

The most simple way i use is the naming of the variables. It’s an indication what it’s used for and therefore easier to trace where it is likely used. But i guess if you have many of them that would be more difficult. ---

I have approx 90 variables of all kind of types, not sure if that’s a lot of not. I do give them self explaining names, but that’s not enough to determine **all** the exact flows (more than 100) they are used in. Thanks anyway for your suggestion though 👍 ---

Try searching for “broken”, not sure if that works for variables. ---

Not a real solution to your problem, but it does help preventing it. What I did is: 1.I installed the [flow viewer](https://community.homey.app/t/how-to-view-your-homey-v2-flows-in-a-browser/7427) (thanks to @DaneedeKruyff) . 2. Your browser will now allow you to print a pdf of all your flows 3. The pdf is searchable, so when you remove a variable, search for it and remove it too ---

Thanks, that might help indeed. ---

I tried in a logic flow card when adding a variable and then searched for “broken”. No results. Could be because there are none anymore, but could also be that your idea does not work. But thanks anyway
