you got it right, I didn't have the TRIGGERcmd Smart Home skin installed, the one that was active was the other two you mentioned. Now it worked, thank you very much.

I installed triggercmd on my windows 10 machine (administrator account). Triggercmd appears in the tray but when trying to add devices to alexa, it does not find triggercmd commands. My computer appears in the list of computers on the site normally but alexa does not find the devices. Both are on the same local network. What could it be? I've tried to reinstall the triggercmd and the skill on alexa but it didn't solve.
