@Michel_van_Lier There is an app called Virtual Device. https://homey.app/nl-nl/app/com.arjankranenburg.virtual/Virtuele-Apparaten/ You could try that one.
That is not the same as the app that you are now asking your question. https://community.homey.app/t/app-pro-virtual-devices-virtual-devices-to-simulate-1-or-more-real-devices/1723
