Your comment cannot be blank.

Featured Comments

1. Only buy plugs that are not cloud dependent and have an offline mode.
2. Buy plugs and "things" that can be flashed to Tasmota. (these don't appear to be)
3. Set DHCP reservations for specific devices with their MAC to IP mapping.
4. Place them on a separate SSID on a separate VLAN that has extremely limited connectivity to other internal networks and the Internet.
5. Control DNS for the devices and return NXDOMAIN for the many obscure, unnecessary, and questionable domains they attempt to connect to.
6. Don't use their "app" to interact with them - use a home automation platform or similar to manage them, and interact with them through the automation app (or use your own custom API calls if so inclined) - see #1.

They take more work initially, but once the initial configuration is complete, I don't worry too much about them. The most challenging part anymore is finding ones that can be easily flashed to Tasmota because many of them switched to a different chip that's not as friendly to convert. However, it sounds like some progress is being made with those through alternative firmwares such as OpenBeken.

Not that most people are doing these things. LMAO
You aren't understanding. By connecting any smart device to your WiFi network, the creator of that smart device can scan or attempt to hack ANY device on your network. That includes your computer, your phone, your router, your NAS, your cameras. And worse, if these devices have security vulnerabilities, then any average hacker can also do the same exact thing to your network.That's why it's so important not to let rogue devices into your home.

In other news, I have had success flashing some KMC devices (not this one) to tasmota/openbk.
Funny you mentioned that. There was a story where a hacker seized control of a casino, via a smart thermostat on a fish tank. https://thehackernews.com/2018/04...meter.html

GorillaBread is right. These types of gadgets are a hole that gives access to the rest of your network. Sort of like keeping your house key under the mat. Sure you only want the cleaning lady to use it but when someone else finds it...

Do people actually trust these things being on their network 24/7? I would at least put them in their own vlan so they can't call home or see any of the other devices on the network.

I'm not really worried about anyone keeping track of how much energy my fish tank uses

The problem is that many of these devices have minimal to non-existent security protocols. So if a hacker gains access to this insignificant and insecure device it gives them easy access to the rest of your network.

Thank you for elaborating on this!

Exactly what I do! Separate networks always for these weird devices. I don't even keep untrusted devices in the guest network because that would be mean to my guests.
