My washing machine doesn't have any bells/whistles/buzzers to let me know when it's done. I just got my first Raspberry Pi and am thinking wiring it up so it texts me when a load of clothes is finished would make a good first project. First thing I need to get started is a way to monitor the current going to the washer. (There is nothing digital on the washer so when it's not running there is no current moving.)
I can think of three options:
- Wire the Raspberry Pi directly to the washer cord to monitor changes.
- Use something that go between the washer cord and the wall that can signal the Raspberry Pi.
- Use something that will monitor current going through the cord externally.
I would much prefer to do option 2 or 3 since I'm new to this. Is there something like a SmartThings SmartPower Outlet that can talk to a Raspberry Pi?
