It depends. Often, apartment electric utility meter panels are clustered together but, if yours is further than 4' from any other electrical equipment, (cable company and telephone company equipment is OK) then the installation will work. The issue may be with the owner of the building since they have the final say on their equipment so you'll need to ask. You might explain the benefit to saving energy to not only you but to everyone on the planet.
Glow provides the feedback you've never had. Energy monitoring has been well studied and when humans are given real-time feedback, they become aware of waste in their home. Typical results from energy monitoring are between 5-20% reduction in overall usage (on average $200+ annually). Additionally, Glow gives you a baseline for understanding what is normal. You can glance at it on the way out the door, or before you head to bed. Its glow becomes part of your home's environment that you're aware of, much like you might notice a faucet that's been left running or a window open when the AC is on.
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.
