Actually, that's exactly what I did and the energy meter will gladly measure a 1W LED bulb. That's why I think consumption is <1W most of the time. At the end of the day, everything <5W or even <10W would be pretty great.
BTW, there are very short bursts of 1W~10W every second. And FWIW, after ~24h, the energy meter shows 0.0117kWh. Obviously, these measurements are a far cry from lab precision, but they do give me some confidence that I won't really notice the server on my next energy bill.
