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.

    Nah, the screen itself is a capacitive touch one. Technically it “flashes” when getting low, but it’s not really helpful.

    I waffled on doing something like that, but once I found the RJ45 I swooned at the possibilities lol

        I do not! Any suggested ones I could try to find?

        My plan is to replicate the wire layout. So first, just use a random 5e and compare the wires. Best case they were lazy and it’s just the same layout with different pin outs. Worst case I’m making a new cable with my large box of cat 6.

        Wave and holler if that plan is naïve 🙂

          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.
