So for a while I’ve been looking at hacking into the wink hub 2. I’ve had it for a number of years and so far it has just worked for what I needed it for. Then wink starts with the subscription nonsense and this morning it refused to connect at all. So time to take it apart.
It’s a pretty easy disassemble.
- 2 screws under the rubber bumper on the device.
- Pull the base free, you’ll see the bottom edge of the PCB.
- The one side snaps of with a little bit of pressure separating the 2 halves. I used a spudger to help it along.
Awesome looks like there are headers on the board again. Lets see the other side.
They were even kind enough to label all of them. So I soldered on a UART header and connected up my FTDI cable.
No surprise here, it’s running u-boot

No surprise that there isn’t source code published by wink.

Maybe if we all ask nicely they will release some.
