Per device energy tallies also give you interesting data.
Home Assistant can do that in the Energy dashboard, and you can answer questions/learn surprising things, like how much energy my "rack" (UPS+mac mini+5 disk bay+a few other things) actually uses vs e.g my fridge or my washing machine, or my desk compute actually is quite low but boy does the screen costs a lot when active, or what does charging the electric bike costs, or what's the effect of setting thermostat to 19 instead of 20 in winter, or oh wow in summer this fan that we use a lot to make things bearable actually ends up using as much energy as our water heater!
(power measurements are done using Shelly Plug Plus S + 3EM + 4PM devices, thermal measurements using Shelly H&T Plus)

Jokes aside, it's also interesting seeing wall draw vs UPS draw vs PSU draw if each piece of your equipment supports that. The Shelly stuff is also quite fun to play with (I recommend a AC adapter for H&T). I have the little black spherical sensors and the data resolution is significantly worse on battery since it tries to sleep in low power state as much as possible. It's fun to see the server cabinet (mine's enclosed) vs room vs different room temps. You can also see when the HVAC cycles on and off and when someone takes a shower (humidity spikes).
