DIY Smart Home HUB + Home Assistant 

Thank you very much! You made me a day! :) As I'm an engineer myself, I really appreciate such kind words from a fellow engineer :)

Well I'm convinced.... This is my first time coming across this channel so I'll subscribe.

@@BenReese Thanks, I appreciate it! :)

Wow, thank you!

Do you mean this version from the video or the next (future) one?

@@SmartSolutionsForHome Both if you can share

I agree, that's why solid documentation is essential in these kinds of systems.

Thanks! Will do!

Thanks!! So far I wasn't worried about "what will happen if I sell the house", but of course you are right! This is a very valid question! I also tried to make my system "reversible", that's why my "smart" installations are parallel to the classic one. I've two sets of cables in the socket boxes :) If something happens to me, any electrician will be able to restore the installation to its default state before my integrations. Thank you for your fantastic comment and kind words! :) As for the "PCB making tutorial", I'm gonna do something like this for a long time. I'm trying to figure out what format it should be.

In the video, I tried to explain myself a bit about this mess. I was supposed to put it in order, but the two years flew by so quickly that I missed it ;) In the second revision it'll be neat :)

Coming soon :)

Thanks for comment! Of course, you are absolutely right! The audio is definitely too quiet :( I was in a rush to render this video and forgot to check the audio level. My bad, but I promise to improve for the future :)

@@SmartSolutionsForHome No worries, mistakes happen. You already gained a subscriber, even with the low audio levels.

If you mean the second revision, it should be here on the channel pretty soon :)

Glad you enjoy it!

Completely opposite approach to mine, but I think both are ok :)

@@SmartSolutionsForHome I have been renovating old house so it was impossible at the time to make a central hub

Thanks a lot!

KNX is a very good choice. I bet it'll serve you well for years to come :)

I replied to your e-mail. And of course you can use any of my projects in your videos :)

Thanks for such an awesome comment!! I'm glad you like my video. I didn't know the word YAGNI, but I love it! I'll definitely use it from now on :)

Thank you! I'm using RPI 3B+. And unfortunately, I'm using an SD card. But for the second revision, I'm gonna use an SSD.

Thanks. I'l try to deliver the follow up it as soon as possible

Hi! I'm form Poland, and my favorite mate (Amanda) is from your country :)

What do you mean? What "compute module"?

Glad you think so!

On this though. Step 1 and Step 2 are often done far too late in development or not at all. In my heating setup, I spent a LOT of time going through the requirements and removing everything I didn't need, forcing simplification. For example. State machines. "If it's ON, toggle = off" etc. Shun them, push them as close to the actual device as possible. Remove any need to actually hold ANY state. Run everything off the message bus, stateless. If your automation needs to know if a radiator or boiler is on, it can ask it. No assumptions. I also removed the whole "right side" of the state machine problem. "When do you turn it off?", "How can you manage mulitple demands for a device to be on, when only one of them asks for it to be turned off?". The solution is, don't turn anything off. Make every request for it to be on timeout. Have devices repeat requests. If anything dies or crashes, stuff turns off naturally and by default. All of that through 1000s of lines of state machine code in the bin and 1000s more not having to manage them at all.

There's a workaround for this. You have to use HACKS. So it isn't a perfect solution, but better than none :)

What's this?

Sorry to hear that. I'm trying my best to be understandable, but I'm still learning English. Maybe someday it'll be easier for you to understand me. In the meantime, you can just skip my videos :)

I appreciate that!

I don't use smart light in my system. I use dumb switches and dumb lights :) And it's thanks to this HUB + Home Assistant it'll become "smart".

@@SmartSolutionsForHome i understand now. Thank you very much for answering. :)

I think it's a popular "attribute" of the engineering mindset :)

I use ge enbrighten smart switches, no extra wiring 100% standalone unit doesn't need coms, internet, wifi or anything to manually switch on and off. Unfortunately it does sacrifice rgbccw control, but i fixed that by setting up secondary colored lights

Thank you, Sean!

My pleasure! :)

Thanks, Felix! "best part is no part" is the ultimate optimization! You can't do better :) If it's not a secret, what are you working on now?

It's an accurate model of my home. I made it in "Sweet Home 3D". It's super simple and free :)

Your concern about voltage drop is perfectly legitimate. I use 12VDC and I think that is the absolute minimum. 5V can be very unreliable. If possible, use 12 or even 24V.

Thank you for your comment. I'll do my best to introduce every detailed aspect of the new project.

In that case, you'll definitely like the second version of my HUB :) It'll be very close to what you described.

@@SmartSolutionsForHome I'm excited, ha ha ha! I'm very keen to make use of those protocols to bring together my smart network. I have them both installed now but don't make use of them just yet.

Welcome aboard! I'm working on V2. Hope to post the video as soon as possible.

Thanks. I know there are good wireless solutions, but they will never be as solid as the wired ones :)

@@SmartSolutionsForHome Maybe. I have wireless devices working for years without any issues. So wireless solutions are solid too and more flexible.

Naprawdę ciężko to oszacować. Najdroższe z tego wszystkiego były SSRy - jakieś 350 - 400 zł. Łącznie z Raspberry Pi pewnie coś koło 1k zł. Ale pamiętaj, że to było jeszcze przed pandemią. Teraz pewnie ze 2 razy tyle musiałbym na to wydać.

I'm on it! Ps. dzięki za komentarz :)

Thanks! :)

Thanks!
