I just have been using esp32's over wireless and a couple of DuPont pins wired to the rx/tx pins and the 5v pin with a buck converter. Does the job if you can deal with wireless oob. If I'm using sfp's they are 10gb and don't want to waste one on oob

@ewenmcneill If you add a relay you also get cheap lights out/power management

@jwp yeah it seemed to me a solution that worked best when you had an all SFP switch (eg, 24-48 x SFP) in the rack, which didn’t have all the ports used, and not much spare rack space. There’ve been other DIY solutions before, but this one seems like a clever compact implementation.
