I was digging this morning for something premade (no sense in wasting the time doing something somebody is already selling on Amazon) and I stumbled on this little DIN power monitoring and remote switching.
You can power up your CNC with voice or smartphone as well as figure out what it’s truly costing you on your electric bill.
I am lazy, I just make the things that plug into the walls report their usage. No wiring or installs. It’s “Hey Google, what is the power consumption of all light bulbs that are blue colored?”
