Can anyone tell me how many watts are used by the LEDs on an Insteon switch?
The specs say the "power consumption" of the switch is 0.59 watts. Is that just the LEDs, or does the switch itself consume power other than the LEDs, and is it constant, or just when triggered manually and/or remotely?
In my searches, the only answers I find are that it is so minimal it doesn't matter; but I would really like to know what the "power consumption" really means.
Thanks!

That's the operating energy use for the entire switch--the receiver/transmitter/repeater; the microprocessor that recognizes when it should respond, when it should transmit, and when it should sit quietly; and the LEDs that show the current dimmer state.

The power consumption is continuous. That includes the LEDs and the circuitry as the device has to always listen for an Insteon signal. It'd take nearly 170 Insteon devices to be the equivalent of a 100W bulb.

Any gear that listens for a signal, such as from a remote control, also uses power 24/7. So do wall warts even when they're not powering anything.

Hey, thanks so much for your answers. A quick calculations shows that my 50 switches collectively take 258.42 KWH per year. At our lower Utah power rate of $0.088/KWH, that is $22.74 per year, or 1.90 per month to have the switches sit there. Dont' get me wrong---I'm not complaining---well worth it to me for the great automation! I had to prove to my wife that it wasn't costing a fortune!

Slightly less than 258.6 KWH if you include leap years

Right! I had to figure that one again. Should have multiplied by 365.2425, instead of 365.0. That makes a difference of just over a tenth of a penny in the average month! But who wants to be technical, right?

An LED requires between about 1.5V to 3V (depending on its color) and typically 20mA to light up. That is 30 to 60 milliwatts per light.
