  • Add automation yaml:

• Change
  • sensor.p1_meter_power by your P1 meter 'Power' (in Watt)
  • 192.168.0.179 by the IP-address of your Shelly plug
• Optionally change the colors:

  • Original colors

    Power	Color
    <=-1000 Watt	Blue
    0 Watt	(out)
    1000 Watt	Green
    2000 Watt	Yellow
    3000 Watt	Red
    >=4000 Watt	Purple

  • Between the values, a gradient is used. e.g. 2500 = Orange

  • Original table

     (-1000, 0,   0,   100),
     (0,     0,   0,   0  ),
     (1000,  0,   100, 0  ),
     (2000,  100, 100, 0  ),
     (3000,  100, 0,   0  ),
     (4000,  50,  0,   100)
    

  • Explanation of the 'stops':

    • Every line contains a Power to color mapping

    • First column is Power in Watt, negative (injection) or positive (consumption)

    • The others are the 3 rgb-colors: Red, Green, Blue (0 - 100)

      Color	R	G	B
      (Off)	0	0	0
      Blue	0	0	100
      Green	0	100	0
      Yellow	100	100	0
      Red	100	0	0
      Purple	50	0	100

  • If you want fixed colors, use this script instead: (only the rgb parameter is changed)
