They're slim in the sense that you can fit two in a regular/dual outlet, one doesn't block the other outlet.
These do NOT have power monitoring, but at ~ $2.50 a piece, hard to complain.

These can be reflashed with the OpenBeken firmware using tuya-cloudcutter (similar to tasmota using tuya-convert).
I've flashed an entire 4-pack the last time this deal was posted.
I usually just follow the readme, but I'm a fairly advanced user, so I don't expect this can work for everybody.
The most 'difficult' part I'd say is installing tuya-cloudcutter.
I happen to have a bunch of raspberry pi boards lying around, so i used a raspberry pi 4 to install tuya-cloudcutter on, which was fairly straightforward.

Once you have that installed, flashing is relatively easy.
Run tuya-cloudcutter.
Follow the instructions shown on screen.
Select manufacturer KMC, and device profile 30153 (not 30154)
Put the device in 'slow flashing mode' (keep button pressed for 4-6 seconds, which will put it in 'fast-flashing mode', release, press and keep pressed for 4-6 seconds again, now the LED should be flashing slowly).
Cloudcutter will do its thing and then instruct you to powercycle the device, and put it in slow flashing mode again.
After that second time, when the device reboots, it should broadcast an OpenBeken_XXX accesspoint that you can the n connect to.
Connect to it, and configure it like tasmota (wifi to connect to, mqtt server etc.).

Again, this isn't for everybody, but for myself, and many others, the benefits outweigh this (relatively small one-time) effort.

I'll see if I can find some youtube showing this process, there's a lot of old stuff out there that no longer applies, no need to break open devices, desolder chips etc.

EDIT:

A youtube video describing the process:

https://m.youtube.com/watch?v=VFsuza3UAhk
Flashing with a custom firmware like Tasmota or OpenBeken removes the dependency on 'the cloud'.

My plugs will continue to function, even if my internet is down (while I'm still at home), and also when the manufacturer's cloud is down (maintenance or whatnot), or when they decide to no longer support the platform, and simply pull the plug (or start charging subscription fees …).

Also, the responsiveness/latency is unbeatable, since I avoid the entire roundtrip of App -> internet -> cloudservice -> internet -> smartdevice.
Instead it becomes App/HomeKit/Home Assistant -> smartdevice.

It's not for everybody. If you prefer plug&play and don't mind installing an app for each device/vendor (and/or use Google/Alexa etc.) then there's no need to flash.

Thanks for this. Nothing worse than buying this to find out they have patched firmware on them.

Have you seen any deals on cheap smart outlets WITH power monitoring? What's considered a good deal for those?

My personal 'threshold' for plugs with power monitoring is less than $5/plug, YMWV (Your Mileage Will Vary 😉).

I paid $5 per plug a few years, for those without monitoring! I stopped after a few because it felt like too much. For monitoring, it seems fair. And the current rating on these simpler plugs still seems pretty good.

If you do not need to flash a custom firmware the Sonoff S40 run about $6.5/plug after discounts.

https://www.amazon.com/SONOFF-Mon...B0B2RBLKBY

Switchbot Mini w/ Power Monitoring can be flashed OTA using the SwitchbotOTA project
https://github.com/kendallgoto/switchbota

$6.38 if you buy 8 with discount.
https://us.switch-bot.com/product...9762811113

Kasa has been my go to for the past few years because I can connect it directly to Home Assistant without having to worry about flashing anything and they are very reliable in my experience. Using the https://github.com/python-kasa/python-kasa project to directly connect to the devices bypassing the Kasa apps.

I usually pick them up off the Amazon warehouse deal for $6-7 when I need to add a new device.
