What do you guys think of the idea of smart homes? I could make a basic setup using https://home-assistant.io to control my home temperature and lighting; the tools for doing this are everywhere nowadays and implementation doesn't seem too horrific anymore.
But setting aside what I "can" do, is this something that I "should" do? How can a person implement this without connecting any devices to the internet?
I've been using homeassistant since the start of the year and I'm never going back! Took a while to get the hang of it but being able to make my own smart electronics on the cheap is bloody awesome. Soldered my plug-in cannabis vape to an ESP32 microcontroller and now I can control its temperature from my phone!
None of my smart-home stuff is closed source which helps a lot with trust, and I've even tested it to ensure that everything works even if my flat's internet goes down! Having all my light bulbs running the FOSS WLED firmware also means that I can hook them up to my HyperHDR setup so all the lighting in my room changes colour to match my TV.
I'm super interested in all these projects! Would you mind sharing guides you found helpful when designing and building then?
For HyperHDR I started with this guide along with a bunch of YouTube tutorials and a lot of trial and error given it was my first time soldering and first time using a microcontroller in a project!
With the cannabis vape I basically used the skills I learned making my HyperHDR setup along with a multimeter and the EspHome documentation (and even more trial and error) to emulate the potentiometer that was originally wired to the temperature controller and to control an LED I wired up to it.
Other than the official documentation the main thing that I found super helpful was the official HomeAssistant forums and (unfortunately) Reddit.
Thank you so much for all these details, this will help a ton! I taught myself to solder a few years ago to do custom LEDs in my kitchen and kid's bedroom, and it was super fun. I'm really excited to try out some of the stuff you did, thanks again!
