Many, my self included, use an Aeon HEM device, to monitor power usage from their washer and dryer. I have used Mike Maxwell’s DTH for an old Aeon HEM v1 Device for years successfully.
However, the v1 devices ar hard to find. There are newer versions available, but I have no firsthand experience with them. I recommend you search the community for Laundry Monitoring solutions. ST_Anything does not have any easy solutions for this.
