My washer/dryer has no smart functionality. I explained it here but I put a device in my breaker box with a clamp on the two lines and that just sends the current to Home Assistant. I read a bunch before I ever tried it and many people have put vibration sensors in/in their dryers. But, this way seems more reliable.
I did my laundry 3 hours faster than usual today because I actually knew when it was done. Worth it to me.
