Hey Dennis,
In the Advanced Virtual Device - Forum from Device Capabilities - Forum you can fully configure as many fields as you would like, and each of the default functions (fields/ShowAs) that Homey has is supported.
If you need help, let me know, i can create a AVD and Share The Device! - Forum even with the Flows in it: The Flow Exchange(r) - Forum.
And if something is missing, DC and the AVDs is fully worked on, so just let me now.
(Custom Dropdowns are on the list, just haven’t found a “real” solution yet, only a very dirty one.)
