Found a device on my network that I don’t recognize, and now it’s bugging me.What I’d really like to do is physically find the thing before I go nuclear and start changing passwords / rebuilding the network.
Is there any app or method that actually helps with that? I’ve got an iPhone if that matters.
If you’re on iPhone, NetSpot for iOS is actually a decent fit here. It has Device Discovery, which shows connected devices and whatever info it can collect about them, and then you can use signal changes as you move around to narrow down where the device likely is.
If your signal search has led you roughly to the right area, but you can’t find the exact spot, start cutting off the excess. Simply disconnect circuits one by one. Keep in mind that many smart dimmers and other internal components only stop producing interference when you completely de-energize the room or trip the circuit breaker.
Yeah, I wouldn’t rotate passwords first unless you actually think it’s hostile. Block internet, keep it contained, then identify it. If the vendor matches a brand you’ve bought before and the signal gets stronger near one part of the house, you’re probably dealing with your own forgotten IoT junk, not some random intruder.
It’s simpler than I expected. I’ll start by searching by vendor and signal source. If that doesn’t work, I’ll go check the circuit breakers.
