The flow that is started by pushing the button is this one. This is the same flow that starts in the morning to turn on the X-mas lights at 06:30. That’s why I put in the set status at the end of it: [https://homey.app/f/uVcjOj](https://homey.app/f/uVcjOj) ---

> [@Roger\_Gorissen](#): > > I think I used the right trigger, the one from DeviceCapabilities. No, sorry, both (de)activating flows use the default Homey Flow cards, that are created because of the Create Flow Cards option. The device also has a few custom flowcard triggers, al starting with “When” (in AF, in normal flows they all end in set/pushed, and are located as first six flowcards, above al other). You need that one for the button. You will only need one (de)activate flow with the correct When card. Then check the value-tag from that flowcard for true or false (logic cards). ---

Thanks! Didn’t know that, wasn’t aware of it. Now I see and understand what you mean. I created a new button to test, without creating flowcards. Then you can see the difference. Back to my problem. IT’S BEEN SOLVED 😀. Thanks! That was just my beginning with this beautiful app. Now I have to find my way in its enormous possibilities. ---

Yeah, i know these different flowcards can be a bit complicated. But the option Create Flow Cards: it makes the field, like a OnOff, the real deal. This is needed sometimes, f.i. for Google Home. But it also creates default Homey flowcards. Those can be “nice to have” sometimes, but are not controlled by an app developer: whenever and however a field (capability) value **changes** , default flowcards will be triggered. ---

Hi, I am struggling with restarting the app after importing a new icon, .svg. “Restart the app” , then timeout after 3000ms. And secondly, how can I get for example degree Celsius (symbol: °C) when making my own app and creating different values that will show temperature. ---

Not sure what you mean here, but have a look at the developer page, it has a lot of info on how to handle Celcius. ---

I have reinstalled the app. It is possible to activate/deactive it. This seems to have no effect on the change of imported icon in format .svg. Tried to restar the app, still getting timed out and I haven’t created or edited anything yet. ---

There are only a handful of apps that make use of the _external_ Homey API (apps that need to read information from other apps for example (Heimdall), or in the case of device capabilities, change more then a regular app can), technically it wasn’t/isn’t really meant to be used in apps, but for web interfaces (like the web GUI and the mobile app), dashboards, etc. But as that is the only way to read out any information outside of your own app, some developers have no other option than to use it. Such apps will also ask for _permission_ when you install such app, as they technically can change (almost) everything in your Homey. ---
