Smart homes in centralized hands, such as Google? Nightmare.

Smart homes controled from your home, like home assistant? Awesome. I have home assistant and done some lights, water sensor, even my security cameras. It’s a lot of work, but it works so well it’s crazy.

I’ve never seen the point, personally. Maybe this is just one of the things i’m too poor to ever understand.

Using home assistant since 2017. As you add stuff there’s more synergy, like a network effect. I have automations and services that:

• Adjust the bathroom floor thermostat according to the prevailing hourly energy price

• Adjust the colour temperature of lighting during the day so blue light is reduced in the evening, allowing natural melatonin production to function

• Announce on a local speaker when our child gets to school in the morning using their phone location

• Operates festive lighting in the winter with reference to sunset and sunrise

• Turns off all lights when leaving; or sometimes if I’m feeling more paranoid

• Replays lighting patterns from a previous week to simulate* occupation

• Sends me an alert if motion is detected and nobody’s home

• Turns off the picture on the TV if nobody’s in front of it for a while using a 60GHz radar sensor

as well as a few other things. I don’t want a smart home that’s just remote operation with a phone. I want to use capabilities to automate things so I don’t need to be concerned about them.

The only smart objects I have are some light bulbs. I think, some processes are good to automate and put software in control of, and some things I want to have explicit control over (I.E. Door locks, Safe locks, AC settings, Heating). Technology can break in fantastical ways, but a lock should just freaking work.

It’s convenient but it’s less secure and less reliable. Imagine being locked out of your house because the Internet is down.

I think you need to ask yourself a few questions: why do you want this? What things do you want to accomplish and how do you see them improving your life? Is the benefit that you gain worth the expense in money and time that it will take to set these things up?

One of the things I made ‘smart’ early on was my garage door. I live in an older house with a tuck-under garage and I had woken up one too many times to find someone had left the garage door open all night. I was tired of constantly going up and down the stairs at the end of the night to make sure everything was closed up and I just wanted a simple way to check, and to close (or open) the garage door if necessary. After the garage door I decided to put sensors on all the doors. Now I didn’t have to run around checking all the doors after everybody went to bed, or if I wanted to turn the a/c on. Next came lights in high-traffic areas, the ones that would get left on all night if I didn’t follow behind everyone turning them off.

In creating all of these wonderful automations where lights would come on magically whenever someone would enter a room I created another problem. Eventually, something important will fail, and the system will break down, and suddenly you realize you have an implicit, unspoken SLA with your partner. I had created an entire household that seemingly couldn’t figure out what to do with themselves in a darkened room if a careless Home Assistant update broke the whole thing. You have to set realistic expectations for these things because no matter how reliable your setup is, one day something is going to fail and you’re going to need to troubleshoot why.

I have provided only a handful of examples but each one served a need that I had at the time in a very busy household with small children and not enough hours in a day. For me, I believe the benefit I received was worth the expense and the hassle of automating these things in my home. If I had to do it all over again today I believe the benefit would be even greater - or, at least, the hassle would have been far less - everything is so much easier now especially with what Home Assistant has become.

Ultimately, you are the only one who can decide if the expense and effort are worth it for yourself.

As someone who has spent many years working on my smart home, I suggest, as do others, KEEP IT LOCAL.

Smarthome well done is good and I think it will be necessary to tackle some challenges of the future - we need smart solutions to use ressources much more efficiently.

But: 85% of all smart home products are neither smart nor good. They are glorified remote controls. Nothing more.

AMAZON ALEXA IS NOT A SMART HOME PRODUCT.

A smart house doesn’t need you to use your phone/voice/etc. to turn down the blinds or switch on a light. It knows when the blinds need to be where depending on your location, the weather (blind based cooling in summer, heating in winter), the time, etc. It inherently doesn’t need a internet connection to control itself - it only does need the internet to expand its knowledge of the outside world,e.g. by getting disaster alerts, weather forecasts or off-site-location. When done this way there isn’t much “hacking” that can be done. There aren’t many components that can turn into botnets.

This is all possible for ages and it is all easily achieved - KNX and other systems are good examples. Matter can possibly achieve that. But currently it’s the big hype to call everything that can be voice controlled smart.

For fucks sake. It takes me longer to say “Alexa turn on the living room lights” than to do it myself or use a Clapping sensor from the 80ies.

Yeah no. As a former IT guy the last thing I want is be tech support for my family’s light switch

I have always been pretty anti-smart homes. But it’s scope crept up on me. Often I wanted more manual automation. Christmas lights were on a light sensor timer power strip, lights going to the garage etc are on old school motion sensors so we didn’t trip.

• The one thing I did do was a thermostat, specifically a Honeywell. It was nice for scheduling and remotely cooling the house when on returning from vacation (or shutting it off if I forgot.)

• Then I got a wifi window ac for my office.

• Then I added some wifi mouse traps to prevent me from having to crawl under the house to check them.

• Then someone gave us a Weber iGrill sensor that was a pain to swap between phones.

Next thing I knew I had 5-6 apps. So I setup homeassistant to consolidate it. The Weber iGrill was the hardest but I had a pi in the kitchen running a calendar so I took a wekend and got it working in homeassitsnt.

Since then I have added some tplink kasa plugs and switches. The plugs are for Christmas lights this year. And one in the kitchen that we can plug a crock pot etc into and remotely start it while at work. The switches work just like a dumb one too. And are all locally controlled.

Finally I got a robot vac which is nice.

I still don’t have Alexa etc or cameras or mics in the house. And anything I do add needs to be only smart as a value add. IE: it should function as normal even without internet.

But yeah. I guess I have a smart home now.

My advice on HomeAssistsnt is make sure you products are supported if you go that route. Stay local only whenver possible. But it is nice. One app controls all. Again for me they all must function as a dumb device as well.

It’s a great and rewarding hobby! But having cloud connected devices on the same network as your sensitive information is an issue.

Use a vLAN and IoT devices capable of local control. Use a self hosted hub like Home Assistant. Keep devices that collect sensitive information (like a camera) out of sensitive areas (like the bedroom). Then you should be reasonably secure.

Just remember, the S in IOT stands for security.

I do have some IOT devices on my network, however they are kept off the internet and on their own vlan. No phoning home (or anywhere else) for these devices.

They can be great if they are set up properly, but too many people just take them out of the box, toss them on their network and think they are just fine.

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.

What’s your network infrastructure like? I have my network segregated across several VLANs, and IoT devices are on VLANs that are blocked from the internet (and the rest of the network) at the firewall level. I can access them, but they can’t access anything.
