So there are a lot of home appliances that I would like to detect status of. Examples would be is the coffee make brewing, what cycle is the washing machine on, things like that. All of these statuses are usually indicated by an LED light on the appliance. I's it out of the realm of possibilities to plug into these LED lights to see if they are on or off? Not by light sensing but through splitting the wire to the led and detecting the voltage?Thanks for the input!
