Ikettle+ifttt

Hi all I’m hoping someone can help. I’ve bought a ikettle 3.0 but I’ve noticed I can’t add it to my smartthings hub so I’ve created a simulated switch and added it to ifttt. Now I’ve got two applets running with ifttt. The first one is if kettle switched on (which is the name of my simulated switch) then turn on kettle. My actual kettle. Which is running fine. Now my second applet is if kettle has finished boiling then turn off kettle (the simulated switch in smartthings) but for some reason it’s not turning off the switch in my smartthings app which then means i have to go into the app to turn off the switch otherwise it won’t run as it already sees the switch as on. I hope this makes sense. Any help would be much appreciated.
