Only 2 things showing in automations as switchable devices

Hello,

Here below all my devices.

My “poort switch” is a “Fibaro dual relay switch” connected to my driveway gate.
I installed a device handler and created 2 virtual switches.
I can control the 2 separate switches from the "Things " page in my Classic app.

But I want to assign a smartthings button to control the relay.
When I go to Automation and add a routine, the app doesn’t show the relay.
When the app asks which device I want to be controlled it only shows 2 devices.

Can someone please give some advice.
What am I overlooking ?

Something not right with your switches they should say on or off on the things page. Search on here for a fibro dh with the model number , it should creat 2 more switch for you itself.

Then there is this for operating

Which DTH are you using for the virtual switches? I’d guess that the DTH doesn’t have the “switch” capability declared.
