I just added a FRIENT Electricity meter to my homey.
It is using an optical probe to count LED pulsations.
On the smartphone, I have these features shown, and except the top left one, I am wondering what are the others made for ?
Any clues ?
The Top-right value should be the momentary used power, the total of all active appliances.
The bottom looks like it gives a “connected” indication, but I’m not sure about that.
