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.
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.
