I’ve been using EmonPi for a few months now and while I was doing some other research (typical link surfing) I came across an energy monitor that caught my attention.
It claims that it can identify what device is being used by the noise/interference from the power line.
I can understand that this is possible as in essence, this is how ethernet over powerline adapters work.
I can understand that each device has it’s own distinct power draw profile (unless it’s a heating element as the draw and resistance changes as it heats up)
The only issue I can see so far (bearing in mind this was a passing thought), is if electrical devices have a similar draw/noise profile on the powerline and the system couldn’t distinguish between the 2. E.G 2 vacuum cleaners of the same make and mode.
While writing this a suggested article popped up
I’ve no idea if this is the same thing as I don’t understand fully what’s being discussed in the article.
Either way, if there was a way of identifying what electrical device is being used and how much power it’s using, then that would just be nothing short of amazing!
I know that there are plugs that you can add in between the wall outlet and the electrical device but this is somewhat of a pain in the behind to go round every single device and measure it.
Do you think this is even possible to build this into EmonPi?
