Prying Eyes: The highly integrated WeMo Switch

Recently, Belkin has come up with a Wi-Fi-based approach to home automation systems called WeMo, which I've been testing in conjunction with Amazon's Echo voice-activated virtual assistant. After you associate a WeMo device with your wireless network via an Android or iOS application, you're subsequently able to control that device via the same application while on your LAN, or optionally even through a WAN connection. For now I'd like to share my hands-on disassembly results, specifically on a WeMo Switch.



Here's what my particular unit looks like from the back, along with a closeup of the product-info sticker:




The two halves of the chassis are held together with four screws, whose heads are of the triangular anti-tamper flavor:



Two of the four are visible; the others are underneath the sticker:



Fortunately, my 30-in-one screwdriver set was up to the task. This is what the inside of the back shell looks like after removal, with the two sticker-obscured screws still poking through it. The mechanical assembly for the factory-reset button, normally at the top of the device, is visible on the left side of the photo:



Opposite it is the "guts" of the device; the digital subsystem is on the left-side PCB, with the power subsystem to the right of it:



Here's a close-up of one side of the digital PCB, still mounted in the chassis:
