I’ve got a non-smart washer, but after a recent power outage I noticed that it resumes the wash cycle at it’s current point when power is cut then restored.
Enter an IKEA smart button and smart plug.
I load the washer, get it started then press the button to kill power and enable an automation (currently on have 4 am and 3 pm).
At 4am or 3pm, the automation turns the power back on and disables itself.
Next step is monitoring the smart plug power monitoring to send a notification when the washer finishes.
Take it one step further and wire a smart relay to the start button.
Why a smart relay instead of the smart plug?
Because then you don’t have to push the button yourself at all. You can still use the smart outlet if you want to track power usage and prevent it from drawing ghost power when not in use.
Ahh, but most of the time I just let the washer run normally. Hence the need for a button not just an automatic start at X times.
