IoT Hack for my Maverick ET-733

  1. Hello, all. I'm a tinkerer and voider-of-warranties who is hellbent on making my Maverick ET-733 part of the Internet of Things (IoT) so I can chart cooking temps/times and other fun stuff. I've even seen a thread here that led to a project where a new device was created to read the radio signal between the transmitter and receiver to do the work. I was hoping to instead hard-wire-tap into the receiver's data feed and manipulate it that way. The simple question so far is, how do I do the wiring to get the data?

    What I've done so far:

    Opened receiver part and identified the various points where the data received by the radio circuit connects to the front panel and display.

    The feeds from left-to-right read: VCC (+5V), PD (not sure what this is), GND (ground), and DATA.

    I then attempted to simply "tap" into the data and GND feeds to see what I could get: nothing. Connecting the power lead (VCC) to my Arduino data logger resets the Maverick receiver, so I know this is too much voltage. I also tried PD in place of DATA to no avail. 

    To start, can any electronics experts see a way to accomplish what I am trying to do or give me a shove in the right direction with respect to the wiring part? BTW, could this have been working and my Arduino data logger sketch have been the culprit? I'd appreciate your thoughts.

  2. Any movement on this project?
    I'm getting one of these for Father's day this year. Can't not hack it if there's info out there. :)
    I'm rusty with my tech skills.
