No, Glow doesn't currently identify individual devices. Interestingly, there's some good scientific research that suggests that identifying specific appliances ("device disaggregation") isn't better than whole-home monitoring, and may, in fact, be worse for saving energy. In "Does disaggregated electricity feedback reduce domestic electricity consumption? A systematic review of the literature" (https://arxiv.org/pdf/1605.00962.pdf), Jack Kelly and William Knottenbelt found that "four studies which directly compared aggregate feedback against disaggregated feedback found that aggregate feedback is at least as effective as disaggregated feedback" for energy savings.
Glow does collect data directly from other devices like thermostats, solar panels, and car chargers so that we can provide the most accurate actionable energy consumption feedback. We are still evaluating if further disaggregation provides any additional benefit.
Additionally, we've found through user testing that Glow owners have no problem doing their own appliance identification. Within a short time (usually a few weeks) users know intuitively what appliances cause high usage. This is because of the real-time nature of Glow's feedback. When you have feedback on your home's usage within 5 seconds of making a change, you understand your home in a way that you've never been able to before.
