Home Assistant AI Automations: Why the New Suggest Feature Can Be Dangerous

Sun, 24 Aug 2025 00:00:00 +0200

It felt like an early Christmas gift: Home Assistant 2025.8 finally promises real AI support for your automations. Imagine being able to press a button and have artificial intelligence suggest perfect names for all your automations. Sounds like a dream, right?

But sometimes the most beautiful dreams turn into nightmares. What looks like a breakthrough at first glance can turn your carefully built smart home into a chaotic naming mess — and the tricky part is you won’t notice until it’s too late.

When Progress Becomes Regression

The Tempting Promise of the AI Suggest Feature

You probably know the feeling: you’ve just built a brilliant new automation and you’re staring at the infamous name field. “Automation 47” would be honest, but not particularly helpful. That’s where the new “Suggest” feature in Home Assistant 2025.8 seems to come to the rescue. One click, and the AI proposes a name. Magic? Almost.

What happens in the background is genuinely impressive: Home Assistant doesn’t just send the YAML code of your current automation to the AI model — it also sends the names of all your existing automations. In theory, the AI has everything it needs to align with your existing naming scheme.

But this is where the trouble begins. In the video, I show exactly what happens when the AI encounters a typical “organically grown” smart home — and why the result is often disastrous.

The Great Naming Dilemma

Imagine spending weeks desperately searching for a specific automation in your list of hundreds. Was it “Blinds down”, “Close shutters”, or “Rolladen automatisch”? Or maybe “Jalousie runter”?

The truth is: most of us haven’t been consistent when naming our automations. Sometimes German, sometimes English, sometimes verbose, sometimes terse. The AI can only work with what you give it — and if your existing names are a hodgepodge, it will only amplify that chaos.

Why This Seemingly Harmless Feature Can Ruin Your Smart Home

The insidious thing about the new Suggest feature isn’t what it does — it’s what it can’t do. It can’t read your mind. While you might have a sophisticated naming scheme in your head (“Room_Device_Action” or similar), that knowledge is invisible to the AI.

The result? A gradual decay of your automation structure. Today the AI suggests “Living room light on”, tomorrow “Activate kitchen lighting”, and the day after “Turn on bedroom lights”. Within a few weeks you have a Babylonian language muddle that makes your smart home practically unusable.

In the video, I demonstrate this using a real installation with over 100 automations — the result is both alarming and instructive.

The Solution: How to Use AI the Right Way

The Game-Changer: Batch Processing Instead of One-at-a-Time

But there is hope! The problem isn’t AI itself — it’s the way it’s being used. What if you didn’t have to process each automation individually, but could make your entire installation consistent in one go?

That’s exactly what I show in the video. The trick is simple yet incredibly effective: instead of letting the AI work on automations one by one, you hand it all your automations at once — together with precise instructions about what the perfect naming scheme should look like.

The Secret Is in the Details

What the Home Assistant feature can’t do, you do manually: you give the AI a crystal-clear assignment. Not “do something sensible”, but “use exclusively German terms, apply the scheme Room_Device_Action, and follow these examples”.

In the video you can see how I implement exactly that — from extracting automations.yaml to feeding the perfectly renamed automations back in. The process is simpler than you think, but the impact is dramatic.

Why Reasoning-Capable AI Models Make the Difference

Things get particularly interesting with large installations. While basic AI models quickly lose the overview, reasoning-capable models like GPT-5 Thinking can identify relationships and develop consistent patterns.

The video shows impressively how the AI doesn’t just assign names — it develops a well-thought-out system. Similar automations are grouped recognizably, edge cases are handled intelligently, and in the end you have an installation that looks as if a professional had planned it from the start.

The Step-by-Step Path to Perfection

The video walks you through the complete process — and I promise it’s simpler than you think:

Step 1: Take Stock

First, download your automations.yaml from your Home Assistant installation. This file contains all your automations in YAML format — essentially the blueprint of your smart home.

Step 2: Choose the Right AI

Not every AI is suited for this task. In the video I explain why I use GPT-5 Thinking and why reasoning-capable models deliver significantly better results for complex naming tasks.

Step 3: The Perfect Prompt

This is where the real difference is made. I show you my tested prompt that turns chaotic automation names into a perfectly structured list. You can watch the AI work and make decisions in real time. The prompt is available to copy in the video description on YouTube — just click into the video above.

Step 4: Patience

While the AI is working, it’s a great time to follow the channel — especially if AI in the context of smart home interests you. This may be my first video on the topic, but it certainly won’t be the last.

Step 5: The Result

The outcome is impressive. What was a jumble of different naming styles becomes a clean, coherent structure. Every automation has its perfect place, similar functions are instantly recognizable, and navigation becomes effortless.

Step 6: Feed It Back

The final step is importing the result back into Home Assistant. A quick restart via the Developer Tools, and your installation shines in a whole new light.

The Outcome: From Chaos to Order

What you see in the video is more than a technical demonstration. It’s the transformation of an organically grown, chaotic installation into a professionally structured smart home.

The before-and-after views speak for themselves: where “Automation 17”, “Kitchen lights on”, “Licht Wohnzimmer”, and “Beleuchtung_Schlafzimmer_automatisch” once sat side by side, you now find a crystal-clear structure.

The Long-Term Benefits

After the transformation you get:

Lightning-fast navigation — you find every automation instantly
Easy maintenance — similar automations are logically grouped together
Professional appearance — the system becomes understandable for other family members too
Future-proofing — new automations automatically follow the established scheme

The Ultimate Flexibility Bonus

The best part of this approach is what I show at the end of the video: total flexibility. Not happy with the new scheme after a few weeks? No problem — just adjust the prompt and run the process again.

No more manually renaming hundreds of automations. No more hours of clicking. Simply change the prompt, let the AI work, done. This flexibility is the real game-changer.

What to Expect in the Video

The video is a complete hands-on guide with no boring theory. You’ll see:

Live demonstration of the problematic Suggest feature
Step-by-step guide for the better approach
Real before-and-after comparisons from a 100+ automation installation
The exact prompt I use
Tips on choosing the right AI model for best results
Pitfalls and how to avoid them

This isn’t theoretical — it’s pure practice. You can start immediately and apply the method to your own installation.

Why You Should Watch the Video

This article gives you a solid overview, but the video shows you the magic in action. Watching a chaotic mess of automation names transform into a perfectly structured list is simply fascinating.

You’ll also get insights in the video that are hard to convey in writing:

How the AI “thinks” and makes decisions
Which naming patterns work particularly well
How to handle edge cases and exceptions
Why some AI models deliver better results than others

Conclusion: The Difference Between Using AI and Using AI Correctly

The new Suggest feature in Home Assistant 2025.8 is a bold first step toward AI integration. But as is often the case with new technology: the first attempt is rarely the best.

The video doesn’t just point out the weaknesses of the current implementation — it gives you a concrete, immediately actionable alternative. One that not only works better, but is also more flexible and future-proof.

The takeaway? AI is a powerful tool — but only if you know how to use it correctly. The Home Assistant Suggest feature is like using a hammer as a scalpel. It sort of works, but the result is rarely satisfying.

With the approach from the video, you have a precision instrument instead. A tool that makes your smart home not just nicer, but more professional and maintainable.

Watch the video, try it yourself, and let the results surprise you. Your automations — and your future self — will thank you.
