In How I changed my D-Link camera to a locally managed IP cameraSmall and sweet. Will give this a try.
For big and broad, try https://github.com/arendst/Tasmota - I'm using MQTT to home assistant with some Athom devices and they're perfect for no-cloud, low work iot.
In Control Esp32 from a web panel over MQTT protocolMany of these WiFi-LED lamps contain esp8266 devices, which have a lot of open source alternative firmware available, like esphome[0] or tasmota[1]. You can reflash them by opening them & connecting a cheap (1$) usb-to-tty adapter.
If that isn't an option (for reasons like not wanting to permanently damage them or being afraid of electrical shocks) a lot of them come with tuya firmware, which you can (still) often exploit and convert with TUYA-CONVERT [2].
I found the Tasmota Device Templates Repository[3] to be a really valuable resource, although I've been using zigbee devices for lightbulbs.

In The S in IoT is for SecurityThere are a lot* of cheap 2.4Ghz wireless outlets that can be flashed with custom firmware that supports power usage & outlet control over MQTT & other protocols. Keep in mind that these devices have to be manually configured & calibrated.
https://github.com/arendst/tasmota/
* Some new versions of these outlets come with firmware that can not be patched/flashed so do some research.
Also most of these are limited to 10 amps of restive load... inductive loads like motors, compressors, and to an extent power supplies, will have peak loads 3-4x there 'real' consumption which can damage the relay if its not rated for the high initial load. If anyone knows of a cheap alternative or cheap DIY that can handle +20A I would be very interested as it would be nice to be able to control things like fridges without worrying the outlet will fail closed

A ZigBee or Z-Wave stick + Home Assistant (or openHAB, Domoticz, others) gets you more reliable operation and no notifying $MEGACORP every time you flick a light switch (or something equally dumb).
Devices based on the popular ESP8266 can also frequently be freed from their cloud overlords with community-made firmware [0], [1] and used as proper Intra-o-T devices.
I decided a while back that I would have no part in this Inter-o-T madness and I think it was a good choice.

Heh, just noticed you linked Tasmota as well while I was writing this. Good project, I use it too!
In Due to a problem with AWS, many "smart" vacuums or doorbells will stop workingLuckily, not everything uses WiFi. There are tons of Zigbee and Z-Wave devices which physically don't have a WiFi chip.
Of course, you should build your own bridge to connect them to (rather than using the bridge of a big tech company).
For Zigbee you can use the Conbee [0] and for Z-Wave you can use the Z-Stick [1] to build your own bridge.
Furthermore, some of the cheaper WiFi devices that are based on the ESP8266 chip can be flashed with a custom firmware called Tasmota [2] to make them cloud-free.

In Smart homes will turn dumb overnight as Charter kills security serviceMy home automation efforts are pretty modest so far, but address definite pain points in my house.
Not really automated at all, but there is a LED in the ceiling near the front door that flashes when the garage door is open[1]. Seeing that light when coming down the hall has saved us heaps of times from leaving the garage door open all night.
I also have laser pointers hanging from the ceiling in the garage that are positioned so when the laser dot reaches the dash you know the car is in far enough.
Another not quite automated addition is using a Sonoff wifi touch light switch[2] in the lounge room[3]. Reflashed with Tasmota it allows us to easily turn the overhead lights on and off from the same remote control for the TV, Amp and Kodi media player. (Works via a script in Kodi.)
Probably the handiest is using an ultrasonic distance sensor

as a presence sensor to tell the computer when I’m in front of it or not[5]. If music is playing when I walk away from the computer, it pauses then resumes when I come back. Also wakes sleeping screens when I return.
Just recently I wrote a little script that displays the number of minutes I've been sitting at the computer in the corner of the screen. At thirty minutes it turns from green to red and plays, "Move it! Move it!" sound, which it'll keep doing every five minutes until I get up and leave the computer for a little bit. (Although I think I'm going to have to change the sound to something that doesn't startle the hell out of me every time.)
Also have an analogue modem on the phone line that lets me initiate calls from my command line by just typing something like, "call dad" and it looks up contact information in my centralised contacts list. It also cross-references incoming caller ID info with the contact list and displays caller info on my computer screen and the Kodi media player[6].
If I were to really get into more home automation in earnest, I think being able to control the curtains in the house would be ahead of controlling lights. Hate wandering around the house opening and closing them all.
Two things I dislike about current trends in home automation are:
1) The requirement for an active Internet connection for a lot of your stuff to work. I want it self contained to the house and not sending information out into the world.
2) The need to have your phone near to you to use half the stuff. E.g., with the lounge room light switch mentioned above I can turn the light on or off at the switch (as well as the remote). I don't have to go find my phone and swipe back and forth five times just to toggle it.
One concept I find very interesting from the late 90's was the adaptive house[7]. It would learn things like your hot water usage, preferred room temperature and ambient light levels and used neural network reinforcement learning to optimise. I wonder how far this could be taken now with advances in machine learning.

[3] Aside: To my mind, in most cases it seems to make more sense to automate the switch, than automate the light bulb itself. Changing a light bulb doesn't need an electrician though, I guess.

Not sure it quite compares to the phone custom ROM community in size but there is an active community. I've reflashed cheap wifi IoT devices which otherwise wanted to phone home with Tasmota[0] which seems like a relatively active project. There are other similar efforts too. You could also consider eg home assistant, openhab or domoticz to form part of this type of community and they're very active.

In Samsung TVs May Upload Screenshots for Automatic Content RecognitionHow do we reconcile a startups need for a walled garden with a customers need for guaranteed functionality even after the vendor shuts down? IMO, as part of the liquidation, vendors should be required to release flashing capabilities on to an open source project like espurna or tasmota. At least this way we can limit e-waste.

In Den Goes Offline for GoodI found that home assistant does not appear to have native integration with Google home the last time I looked? I ended up using openhab which has native Google and Alexa integration, although I am not a fan of openhab as it feels ludicrously over-complicated for even the simplest of things.
My lesson learnt after several years going through smartthings, home-brew stuff with raspberry pis, home assistant, demoticz, and openhab using ZigBee or zwave is to make sure your core infrastructure (i.e. things you want to control) is MQTT-based running over wi-fi/ethernet and all your plugs/lights/etc are independently controllable via sending raw MQTT commands on your home network.
If you need to rely on a working internet connection, or too many third party things (e.g. IFTTT) you are going to have a bad time when things inevitably break/change

/have an outage/become inexplicably slow/get shutdown etc. Once you standardise on MQTT you can switch out HA/OpenHab/others with minimal fuss, and you have great controll and backup options. WiFi just seems rock-solid Vs ZigBee or z-wave that just seemed so troublesome and unreliable.
Tasmota (1) + mosquito running on a RPi has finally given me a reliable set up after years of struggling. It is some rock-solid MQTT compatible firmware for ESP8266 devices.
1 - https://github.com/arendst/Tasmota
Basically anything that can be flashed with open firmeware, such as Tasmota (https://github.com/arendst/Tasmota/wiki/Prerequisites) plus a local instance of Homeassistant.
It needs a bit of work and sometimes soldering skills, but some devices can be flashed without soldering and in general it’s not too hard to do. :-)
