Seems pretty easy to open up. One philips screw from the front. (Needs a skinny screwdriver tho...)

First thing you see is the important part (From a hacking viewpoint).
[[File:Sonoff D1-Inside.jpg|none|thumb]]
There're actually 2 boards with a 4x2 interconnect.

All the power stuff is on the one on the right.

The one on the left is the WiFi & RF board.

===There are 2 switch locations on the board.===
S1 is un-populated but seems to be for a push-button on the ESP chips GPIO0 pin.

S2 is a slide switch labelled "OTA" (Not the default position...). This switch appears to be accessible through a small slot in the front cover of the unit.
