A couple of nights ago, I noticed something strange with CO2 levels at home. Usually, it goes up in the bedroom at night, but this time I saw it rising in the living room too. I have an automation that increases the speed of my supply & exhaust ventilation (HRV), it triggered, but CO2 didn’t drop.

It’s summer here - hot during the day (+28°C), but the last few nights it dropped to +8°C. The ventilation unit switched on heat recovery. I even started thinking maybe the rotor is leaking exhaust air back into supply.

Last night CO2 started rising again. I set the ventilation to full speed and turned on an extra fan to move air around the house, but levels didn’t drop at all. Checked my supply air with a sensor - ~700 ppm. Took it outside - also ~700 ppm (I regularly calibrate my sensors).

This morning I checked again outside - 420 ppm. So it seems CO2 is genuinely higher outdoors at night/evening. I live near a forest, no factories nearby, few neighbors (nobody is heating right now), and the weather has been completely still with no wind.

Question: is this just a temporary thing during calm weather and temperature inversion, or is outdoor CO2 always higher at night? Why does it happen? Do you take this into account in your ventilation automations? Anyone here tracking outdoor CO2?

Google just released Gemma 3 270M which is extremely fast on old/edge hardware. Seems like a neat model for simple text based AI tasks introduced with HA 2025.8. Fine tuning for the task could be necessary. Following instructions requires a well crafted prompt. Probably not what you're looking for as far as conversational assistant. Entity extraction is probably the most practical application so far.

Here’s when it’s the perfect choice:

• You have a high-volume, well-defined task. Ideal for functions like sentiment analysis, entity extraction, query routing, unstructured to structured text processing, creative writing, and compliance checks.
• You need to make every millisecond and micro-cent count. Drastically reduce, or eliminate, your inference costs in production and deliver faster responses to your users. A fine-tuned 270M model can run on lightweight, inexpensive infrastructure or directly on-device.
• You need to iterate and deploy quickly. The small size of Gemma 3 270M allows for rapid fine-tuning experiments, helping you find the perfect configuration for your use case in hours, not days.
• You need to ensure user privacy. Because the model can run entirely on-device, you can build applications that handle sensitive information without ever sending data to the cloud.
• You want a fleet of specialized task models. Build and deploy multiple custom models, each expertly trained for a different task, without breaking your budget.

Have you ever ditched one protocol for another? Like, did you get fed up with Wi-Fi devices slowing down your network and switch to Zigbee? What was the tipping point for you? Was it speed, reliability, or something else?

Or maybe you've been a die-hard fan of one protocol from the start. Why did you stick with it? What makes you so loyal?

Hi everyone, im looking for new ideas for automation/sensor/switches and unique stuff people love in their smart homes, I know there are expensive stuff that are really cool, but I’m wondering what cheap things I could add to my smart home that won’t break the bank at all!

I lived in Apple Home for years, then moved my backend to Home Assistant for the integrations and the automations. Two things held me back from going all in on the frontend:

1. UI feedback felt slow, a toggle could take 2–3 seconds to visually update.
2. Keeping a good looking dashboard up to date was a chore.

So I built two plugins to solve exactly that.

1) Optimistic Feedback

Repo: https://github.com/nitaybz/optimistic_feedback

Available in HACS, search “Optimistic Feedback”.

What it does: when you tap a card, the UI updates immediately, then reconciles with the real state. The result feels snappy and human, like the best native mobile UIs. If a command fails, it corrects itself. The goal is simple, make HA feel fast without faking reality.

2) Apple Home Dashboard

Repo: https://github.com/nitaybz/apple-home-dashboard

Available in HACS, search “Apple Home Dashboard”.

What it does: a pixel-perfect Apple Home style dashboard for HA users who like that clean layout. Edit mode, drag and drop ordering, per-tile settings, sections and favorites, quick actions, and more. I tried to capture the interaction patterns that make Apple’s UI pleasant, then added knobs that Home Assistant users expect.

Why I built this: Apple’s progress on smart home and AI feels stuck, so I decided to make HA feel just as immediate and polished, while keeping all the power HA already gives us.

If you try it, I would love feedback, feature requests, bugs, real world edge cases, Issues and PRs are open on both repos.

Seeing this and the long range support is very impressive. Well done HA team!

Hey everyone,

I'm trying to pick a smart dimmer switch and want to know what's really good out there. Do you have a favorite brand you're a loyal fan of? Tell me what it is and why you love it!

• What brand and smart ecosystem are you using? (HomeKit, Google, Alexa?)
• What's the one feature that makes it a winner for you?
• Any compatibility headaches?

Thanks for the help!

So finally bought my first matter device a wiz light bulb. I assumed it would be as simple as all my zwave devices. Power it up, scan the code and be on my way. Nope, not with Matter. After numerous failed attempts I finally got it working…after connecting to the cloud and enabling matter lmao. So here’s what I had to do:

1. Join the bulb to my main lan. Nope, couldn’t add it to my IoT net. This puppy said let me phone home.
2. Update the firmware
3. Enable matter
4. Add it to home assistant.

So it’s a fully local device…after connecting to the cloud first. Are all matter devices like that? I just can’t fathom how this replaces zwave
