Only thing Trådfri that doesn't work are those cheap buttons with the 0 and 1 on them and their motion sensors.
That was exactly one of my problems. As every Tradfri-user I have several of their switches, including the basic dimmer switch (the one with 0 and 1 on it) and their scene switch (the round one, allwong you to dimm and change colors). As far as I've seen it, I assumed both can't be paired with Hubitat.
It is possible to control devices that are one Google Home using Google Assistant Relay, but that's a little advanced.
Yeah, that was mentioned before. I think this will be way over my head right now. 
I've a life science backround and had never anything to do with computer science so I'm a extreme newb. But thank you for that. I'll try if I can wrap my head arround all this. I'll just be very slow.
