ESPHome on the Etekcity NightLight plug and 2 & 6 Channel Power Monitoring



Finishing up the last bit of sensors and config on the Etekcity power monitoring plug.  No soldering required to flash the plug as they left us an open header to attach to.  Snuck in a little bit of the cool 3 way Martin Jerry switch.

Audio issues on the first piece, but we reset OBS to fix the issue!  Sorry guys/gals!
