TP-Link HS110

A smart plug with energy monitoring

Danger to life!
Never connect the device to mains power. Use a safe separate 3.3V supply for the wifi board.

Contains a MAX71020A, connected over SPI for power monitoring

DANGER: HIGH VOLTAGE inside!
Opening this device exposes
parts under high voltage (110/230 VAC)!

  • Risk of deadly electrical shock
  • Risk of irreversable damage to other components attached, e.g. your PC connected via serial

Make sure to keep your fingers, conductive tools and serial cables away from the high voltage at all times!

Capacitors can still retain dangerous voltages
after disconnection from mains!

Continue at your own risk!

FIXME Describe what needs to be done to open the device, e.g. remove rubber feet, adhesive labels, screws, ...

  • To remove the cover and open the device, do a/b/c
