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.

    Quick question the low fuel indicator is it some sort of coloured LED?

    If so you could just use a small photo sensitive resistor over it and when that lights up send data to something like home assistant.

      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.
