This is why my doorbell is on a separate VLAN, without internet access.
This was honestly more secure than I expected. Nothing that would survive defcon but that’s a neat sync protocol.
Does anyone ever wonder why a doorbell needs to be connected? I do, so I don't have one. Diminishing returns by design? I've never been like "oh I am glad my doorbell is connected to my network". Wondering what marketing I didn't see (and fall for).
This is just one reason I prefer zigbee for smarthome devices. There is a protocol-level isolation between them and my home network. Really sad to see zigbee devices getting rarer
