Good question
The reason I guess is I haven't found one that does what I want...
There is this one, [RELEASE] Laundry Manager, but from what I have seen it relies upon reseting the washing machine to "idle" by pushing a button. The WAF will go out the window if she has to push a button every-time she changes the laundry.. might be a small thing to do, but trying to make this more automated not less.
"Can assign a button to reset status to any finished status to idle (I have a Samsung button mounted near the W/D to quickly reset the status)"
I don't know why they don't have it setup with a door sensor so when the door opens it gets reset. Even if you open it to throw in something new, it should just go back to a running state as power levels will reach the trigger point.
Are there any better ones out there I might be missing, I have done some searching but haven't come across one. I don't think the Rule I created would be that taxing on Hubitat itself, the rules really only run while the wash machine is on which is only a few hours a week.
