I’m sure Andy’s port is going to work well for you. If not, I did this for my washer and dryer. Dryer works perfect, every time. I had a delay of 30 seconds for the dryer because I was using ST for notifications and wanted to be sure they happened. Now that I’m using IFTTT, it can be removed. Washer delay is longer because the current fluctuates close to the off state, toward the end of a cycle, as it shifts the clothes for a high speed spin, and then again to loosen clothing from the drum at the end of the cycle. Haven’t figured out how to consistently avoid multiple notifications toward the end of a cycle yet. Dryer drops to 0 every time though, and is very reliable with just a single notification that is always accurate.
