Power Dashboard with PC controls

enter image description here Control your PC and monitor the power consumption of connected device. I used a NETIO cable to power up my PSU (a similar effect can be achieved with Sonoff POW R2) to take over the control and measurements.

Features:

  • Online Dashboard
  • Dynamic buttons
  • WOL, Sleep, Restart PC options
  • Total and Daily Cost
  • Total and Daily Power use
  • Total and Daily Up time
  • 7 Day dynamic chart
  • Secure restart
  • 2FA Restart authentication

You will need the following nodes:

  • node-red-dashboard
  • node-red-contrib-wol

This article uses 2FA tutorial and build on the washing machine notifications.

You will also need:

or

Settings

  • Refresh Rate time interval in seconds to get the readings
