- No, I don’t believe Sense will “find” servers behind a UPS for two reasons. Some UPSes will obscure the signatures of the devices on the protected side. But even if if you had them plugged in directly, servers, like many electronics don’t really have a definitive on-signature, plus any regular patterns that they might have (booting) are hidden behind an energy-use-flattening power supply. I would suggest an HS110 or HS300 - you’ll get a better picture of your server usage.
- I have put my 2 Sonos units on an HS300, because, being electronics, they are also unlikely to be detected by Sense. My discovery from that is that they use far more power in standby than I would expect - 7W each. So I have used my HS300 to power them down most of the time.
- You can see a bunch of hourly energy use profiles for my devices on Smartplug above and in this link (includes Sonos)
