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...

And you expect everyone is an expert of managing multiple subnet and wifi from the same router? Nice try, lol.

How do these compare to the TP-Link Tapo Smart Outlets (https://slickdeals.net/f/17338125-costco-tapo-mini-smart-wi-fi-plug-4-pack-matter-certified-19-97) that were recently on sale at Costco?
The Costco smart plugs have the Matter standard built into them, and these don't. To make it more complicated, some plugs are starting to come out with the Matter and Thread standards. Newer hubs are required, but many hubs/devices/routers that people already own support it. Ideally the matter/thread standards should work across all smart home setups.

My belief is that smart plugs prices are plummeting because they have to get rid of inventory before the newer devices start to catch on. Many Matter/Thread devices were supposed to be out in 2023, but they are only now starting to appear in 2024.

Thanks everyone for the insight on how people are using these plugs I have an outdoor one, a few Amazon and TP-link indoor ones and one that is like a power brick with 6 receptacles, that I have never used. I also purchased a few extra Echo Dots 4th edition with the line out so I can pump music into the stereo. I have a number of older equipment that maybe I should hook up and turn off when not used. Now for some planning on my part.

Take a look at Emporia Energy Smart Plugs. The are a much better choice. Support WPA3 and their app is the best thing I have been able to find for this type of device. Also, they now log Voltage too. -Bill

Does anyone have these? Do they work with the Tuya app?

Edit: looks like someone says it is Tuya app compatible.

These are Tuya based so for those with homebridge, set this up with the Smart Life app instead. Been running smoothly for years now and still google/alexa integrated properly

Just what I was looking for.

Get the set from TP-Link Kasa. They are double but honestly these will fail fast and you will want a nice system. My Kasa's have been great!

Fair enough, however the audience is indeed everyone, lol, so might as well to give a disclaimer for the benefit of doubt. Thanks for sharing, it's all good.

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've got the same answer for anyone who is paranoid about privacy. At the end of the day, do you really think there's a room full of people gathering information about you and somehow using it against you? Unless you're a celebrity, or a government figure, you literally have nothing to fear from data mining. Trust me, they aren't interested in you.

Routers have had guest network capabilities for years now, and all configurable via the GUI; no advanced networking knowledge required.

For example, the ASUS GUI has an option to isolate the guest network from the main network (if you want to use the plugs with their app via the cloud).
