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...

I am looking for a power monitor for home assistant. Do you have any recommendations?

I was looking into it, but it seems like one brand work, then they did something, and it doesn't work anymore. I think it was tp link.

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

Quote from EfficientSnail709 :
Appears to be rated at 15 amps (based upon the claimed wattage rating), but it would be nice if they specified that (as they should)! Also, I would prefer that these were UL approved (vs. ETL). Good price....but the lack of stated ratings and safety approvals are important factors to consider!
Isn't ETL certification equivalent to UL listing?

I found this document written by Leviton (manufacturer of lighting/switch products) on a CBS news website. https://www.cbs17.com/wp-content/..._ETL-1.pdf

I also went with Amazon warehouse kasa plugs for the same reason. Not sure it makes a difference in the end but these Chinese brands on my wifi do give me that worry
Kasa is made byTP-Link, which is a company based in China. FYI.

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.

Does this mean setting these up on 2.4g and keeping my other devices on 5g? Or setting up a complete different internet for these?

It depends if your router supports it. Easiest way would be to make your router create a "guest network" and connect all your IOT devices there.

I bought these around December last year and didn't get around to setting them up until after return window closed.

My recommendation is to absolutely stay away from KMC. They are constantly going offline whereas my Kasa, eBrighten and Aoycocr have never had issues in years.

Check the reviews, this is a constant complaint. The savings is not worth the headache of having these be offline most of the time.

I run the Sonof S31's for HA. Flashed to Tasmota and run locally. $28 for 4 on Amazon after $6 coupon. You'll need about $10 in tools to flash them, or if you aren't able to flash yourself, grab them for $14 pre-flashed from various vendors (though usually OOS or backordered that way).t

https://tasmota.github.io/docs/Ge...d-software

https://tasmota.github.io/install/

If you're talking whole home Power then the Emporia Vue used to work but heard same some issues. There's various others that are ESP based but 2 - 3 times as expensive.

I use one to turn on a fan when it gets hot enough in a room. Lets me stick with windows for ventilation a little while longer before turning on the AC.
