My favorite is the ATTINY 85. It's so cheap and yet, it can do almost most of the things you can do an Arduino. And yes, you can program it using the Arduino IDE as well. Last year, I started out to digitalize my entire house with these tiny ATTINY 85 chips and with some nrF wireless chips. It has worked really well for me and I'm able to control and monitor any power port in my house as well as my mains. The overall…

Do you have any write ups or code on this to share?

Amazing article! (I was utterly unaware that this amount of choice and selection of microcontrollers exist, much less at this price point(!) -- before having read this article... you put a lot of work into this article and it shows.)

This will be my new, first, go-to article, if I begin any new projects involving microcontrollers in the future...

This sounds really interesting and is something I’ve been meaning to do for my house as well. Do you have a blog post with the details or a github page?

It's missing the below 5 cents microcontrollers: https://lcsc.com/product-detail/PADAUK_PADAUK-Tech-PMS150C_C...

How is the documentation on those?

Not great, Dave from EEVblog did a few videos on them and how to use them. I think they're all OTP

Totally with you. The tiny original Digispark (with the USB traces on the board itself) is my fave - I use them for teaching school clubs and personal projects/gifts. If I need to go beyond that, it usually means straight to the ESP8266 or ESP32. But that's pretty rare. (With you on the nRFs, too!)

I like MSP430 a lot but the tooling leaves a bit to be desired. Maybe that's been improved upon recently by TI but a few years back you were left with few choices other than installing some kind of IDE on Windows.

You can use open sourced MSP-GCC developed by RedHat now and it makes things a bit better and more flexible about how you want to develop

Sounds fascinating!

>> yet, vastly more powerful

What's sorts of things can you now do with this setup?

What's your experience with running your server non-locally? Not judging, just curious as usually those that DIY their home automations are also into homelab stuff and setup a spare laptop or something for the server.

Derp - You're a cloud consultant, oh okay haha. I'm guessing your home ISP network is pretty reliable then? I'm stuck on con-cast so unfortunetly I have to be prepared for occasional high-packet loss/no internet situations. They're fairly rare, but I want to make sure my lights can be controlled 24/7

This is such a great setup.

Maybe if we just put 10 of these mini-controllers in each home, we can cover the majority of electricity consumption, and get demand flexibility the cheap way (instead of fitting each home with an expensive smart meter).

(Obviously the cloud/app parts will have to be centralized with consumer opt-in and preferences etc..)

Have u thought about this ?

Has this approach been explored ?

great project..

How do you like the nRFs? I've been all over the ESP8266/ESP32 since it came out, they're crazily versatile chips!

I've been interested in Lora/nRF/LoraWAN for some of my low-power further range projects. I'm just curious as to how they compare to the ESP's.

Also, how do you power your projects? I'm considering buying 6+ usb bricks, but I'm skeptical of non-brand name ones, and brand name bricks are expensive. After watching BigClive though I'm sure I trust any non-brand name ones....
