If all you want to know is when the cycles are complete, it's easy to do without trying to decipher Samsung's wifi output.
The end of cycle signals on my LG washer and dryer can't be heard in my living areas and LG smart app requires precise location permissions enabled all the time to function. Not gonna happen.
A power monitoring Zigbee plug was an easy solution for the washer but I could find nothing like that for a 220V dryer. A ZigBee vibration sensor did the trick even though the units are stacked.
