The reason I can say my smarthome is relatively secure is because I don't allow any of the devices to access the internet. IP or not seems irrelevant.

- ocdtrekkie 7y agoThe high level of sophistication of IP networking and the fact that one small mistake could mean your devices access the Internet is why a network that doesn't talk IP is almost inherently safer than one that does.

- ViViDboarder 7y agoThere is a great point here you haven’t made yet. It may seem trivial for those of us on HN to block IP devices from the internet, but the average user will not know how to do that effectively. They are also the ones who’s devices probably remain on a botnet undetected by their owners. That said, most hubs (required for these types of devices) connect to the internet by default anyway. It does reduce risk a bit as vulnerability in a node isn’t exploitable remotely.
- icebraining 7y agoThere's no sophistication: just plug a Wifi router to an outlet but not to the Internet cable.
- orev 7y agoI think any home automation system should not have to rely on the home owner having a CCNA cert in order to be secure.
- icebraining 7y agoBuying a Wifi router and not plugging it to the Internet doesn't require a CCNA cert. Yes, it's an extra device, but so is the Zigbee hub.
- orev 7y agoMost people are not going to buy a dedicated WiFi AP just for their home automation. The benefit of Zigbee, even when using a hub, is that you don’t have all the actual devices on your network, calling home, and possibly opening up NAT traversal streams. You just need to worry about the hub. With WiFi devices, you need to worry about all of that for all of them.
