It's real easy to trigger A tuya device in Smartthings, but I need to go the other way. I need to trigger something in Smartthings from Smart life. I tried adding a Virtual switch in Smart life to use IFTTT, but it does show up in IFTTT.
Like physical Tuya devices, Tuya virtual devices have different 3rd party integrations. Most have Alexa and Google home, a few have IFTTT and a few have SmartThings (ST) integrations. Find one with a ST integration and bypass IFTTT. One of the virtual Brazilian power strips has a ST integration and it will give you multiple visual switches that will show up in ST
