Howdy, long time lurker!

I was wondering if anyone could give me a hand with trying to pull data from my Harmon Absolute43 pellet stove. Looking at the board, I see an RJ45 connector and thought "seems like a wireshark-like sniffer would do the job".

However, all searches end up looking at networking rather than simple data sniffing. Any ideas as to how to add a "bridge" that also stores the data? From there, I can do the publishing side of things, just the hardware component for me has me scratching my head.

I bet it is something simpler than Ethernet. I would open it up and look at the board. First I would look for magnetics because that would indicate Ethernet. I would look for labels on the silkscreen. I'll bet it is something simple.
