All measurements are on the primary side of the power brick. Therefore, they include all the power lost in the power brick.
Idle (just running, not serving any pages) 1.39W
The power strip reports a power consumption of 0.011kWh for the last nine hours.
Sounds very acceptable. You can hardly wish much better values.
So far as I can read it on the internet it seems to be the same or more or less better (depending of the power loss of the power brick) than the most economical Raspberry Pi with LAN (I assume that's the Raspberry Pi 1 B+).
(But the Internet does not always report the same consumption data and it is not always clear which mode of operation is meant.)
Thank you for your effort!
