I’ll take a look at your code tonight if I have time. Meanwhile, below is what I have so far. My washer/dryer turn off entirely then the cycle is done, so I don’t see any need for timing the inactivity periods. Whenever the power consumption goes to zero - the cycle is done. The “if (power > 8)” bit is to prevent starting the cycle by accidentally pushing the power button on the washer (I have two kids, so “accidents” happen all the time). My washer consumes 8W when it’s on but idle.
