Home automation peaked in marketing promises around 2022. Every device would talk to every other device. Your home would anticipate your needs. You’d control everything from one app.

Three years later, I have 40+ smart devices across five ecosystems, three apps I actually use, and a drawer full of abandoned smart things that never worked right.

Here’s what I learned about home automation platforms after three years of trying to make this stuff actually useful.

The Ecosystems

Apple HomeKit — Works with iPhones/iPads, privacy-focused, limited device support.

Google Home — Works with Android, broad device support, data-hungry.

Amazon Alexa — Works with everything, clunky app, voice-first.

Samsung SmartThings — Hub-based, supports Z-Wave/Zigbee, requires hardware hub.

Home Assistant — Open source, runs on your own hardware, steep learning curve.

What I Actually Use

Apple HomeKit is my primary platform because I’m deep in Apple ecosystem. Setup is usually simple (scan code, add to Home app). Automations work reliably. Everything runs locally when possible (privacy win).

The problem: device support. Plenty of lights, locks, thermostats work with HomeKit. But that random smart plug or sensor you want? Probably doesn’t support it.

I’ve worked around this with HomeBridge (software that bridges non-HomeKit devices), but that requires a dedicated computer running 24/7. Not exactly simple.

Google Home fills the gaps. Devices that don’t support HomeKit usually support Google. The app is worse (slower, more cluttered), but it works.

I have both installed. Lights and locks in HomeKit. Random gadgets (robot vacuum, air purifier, fans) in Google Home. Not ideal, but functional.

Home Assistant is what I wish I’d started with. It’s open source software you run on a Raspberry Pi or old computer. Supports basically every smart home device ever made.

The catch: you need technical comfort. YAML config files, command line, network troubleshooting. Not for everyone.

I set it up last year. Took a weekend to get basics working, another week to migrate everything from HomeKit/Google. Now I have one system that controls everything. Automations are more powerful. Nothing relies on cloud services.

Would I recommend this to my parents? Absolutely not. Would I recommend it to anyone comfortable with technology? Yes.

The Devices That Actually Add Value

After three years, here’s what I actually use regularly:

Smart lights (Philips Hue). Worth it in living room, bedroom, office. Not worth it in hallways or bathrooms where you just flip a switch anyway.

Smart thermostat (Nest). Paid for itself in energy savings in 18 months. The scheduling is genuinely useful.

Video doorbell (Ring). Package theft dropped to zero. I can see/talk to delivery people remotely.

Smart lock (August). No more keys. Give temporary codes to guests/cleaners. Lock automatically when I leave.

Motion sensors + automations. Lights turn on when I enter a room after sunset, turn off when I leave. This is the only automation that feels genuinely futuristic.

The Devices I Regret Buying

Smart plugs for everything. I bought 12. I use 3. The rest are in a drawer because controlling a lamp from my phone is slower than walking over and flipping a switch.

Smart speaker in every room. I have four. I use one (kitchen, for timers while cooking). The others are just expensive ways to ask about the weather.

Smart smoke detectors. They cost 3x more than regular ones and the “smart” features (phone alerts) triggered false alarms constantly. Replaced them with regular smoke detectors.

Smart garage door opener. Worked for six months, then stopped responding. Troubleshooting required firmware updates, router changes, and tech support calls. I installed a $30 dumb remote instead.

The Automation Reality Check

Here are the automations I use daily:

1. Lights turn on/off based on motion and sunset time.
2. Thermostat adjusts based on schedule (warmer in morning/evening, cooler during day/night).
3. Lock automatically locks when I leave (phone location trigger).
4. “Good night” scene turns off all lights, locks doors, sets thermostat.

That’s it. I’ve created dozens of other automations (coffee maker starts at 7am, music plays when I arrive home, etc.). Most lasted a week before becoming annoying.

The useful automations are invisible. They do one thing reliably without requiring thought. The useless ones require maintenance, break randomly, or do things I don’t actually want automated.

Platform Comparison: What Actually Matters

Reliability: HomeKit and Home Assistant win. Google Home has cloud outages that break automations. Alexa is fine but slower.

Privacy: HomeKit and Home Assistant process locally when possible. Google and Amazon send everything to the cloud.

Device support: Google and Alexa support the most devices. HomeKit is pickier. Home Assistant supports everything but requires setup work.

Ease of use: HomeKit is simplest for basic stuff. Home Assistant is complex but powerful. Google is middle ground.

Cost: HomeKit/Google/Alexa are free (apps). Home Assistant requires hardware ($35 Raspberry Pi minimum, more realistic $100-200 for better hardware).

The Actual Recommendation

If you just want smart lights and locks: HomeKit (if iPhone) or Google Home (if Android). Simple, works.

If you want broad device support without technical work: Google Home or Alexa.

If privacy matters: HomeKit or Home Assistant.

If you’re technical and want control: Home Assistant. It’s worth the learning curve.

If you’re not sure: Start with whatever ecosystem matches your phone (HomeKit for iPhone, Google for Android). Buy a few devices (lights, maybe a smart speaker). See if you actually use it. Don’t go all-in until you know it adds value.

What I Wish I’d Known Earlier

Start small. I bought 20 devices in month one because I was excited. Half of them are unused. Would have saved money buying strategically.

Ecosystems matter. Switching costs are high. Once you have 20 HomeKit devices, migrating to Google is painful. Pick early, stick with it (or go Home Assistant from the start).

Cloud dependence is risky. Several smart device companies shut down in the last three years. Their devices became expensive paperweights. Buy devices that support local control when possible.

Voice control is overrated. Marketing videos show people saying “turn off the lights” from the couch. In reality, pulling out your phone, entering your passcode, opening the app, and tapping “lights off” takes longer than using a switch. Automations (motion sensors, schedules) are better.

Most smart home features are solutions looking for problems. I don’t need my fridge to tell me I’m out of milk. I don’t need my mirror to show me the weather. These features sound cool in demos, deliver nothing in daily use.

The Bottom Line

Home automation adds value in specific scenarios:

• Lights that automatically adjust for time of day
• Thermostats that save energy
• Locks/cameras for security and convenience
• Voice control in kitchen (hands-free timers while cooking)

Everything else is either marginal or actively annoying.

Start with the basics. Resist buying every smart device. Stick to one ecosystem. Automate sparingly (only things you do the same way every day).

Home automation can be useful. It’s usually not as useful as the marketing suggests.
