Thanks for the question @bryan,
@senseinaz and @kevin1 are right, Network Device Identification or (NDI) is looking for any on/off clues from devices on the same network as Sense. Some devices on the network are really good about providing clear and consistent pings (Samsung TVs are remarkably polite…) while others can create quite a bit of noise that we’re working our way through over time. Those pings are used to inform the traditional model building and load calculations, as none of these network pings broadcast any information about how much power said device is using, so your monitor still needs to build a model for measurement which takes some time. With that being said, we won’t be able to immediately identify all the devices on your network, but with NDI enabled, you’re helping contribute to this research so we can figure out better ways to parse the network data and get better device identification to the entire community!
I hope that’s helpful. There’s a bit more information in this blog post if that’s useful:
