Been working on this one and proud of where it’s heading. Take it for a spin and tell us what’s missing.

🎉 The preview of our community-powered device database is live! Think "Wikipedia of smart home devices." Powered by real-world usage from thousands of Home Assistant users who opted in back in February, this is just the first step. More to come as we keep building in the open.

I've been in UX for 40+ years (I started at Apple). Recently, I've been working on bringing UX to FOSS projects, and I see this attitude far too often (but not always!). It's terribly exciting to see this thread get so much support and love. There is hope yet.

𝗪𝗲 𝗯𝘂𝗶𝗹𝗱 𝗶𝗻 𝘁𝗵𝗲 𝗼𝗽𝗲𝗻 We are so excited to share the first design ideas for the @openhomefoundation.org Device Database! We build in the open, and that means sharing work before it is finished. So here it is: a clickable prototype of the Device Database, and we would love your thoughts on it.

From there, we have ideas for richer device pages and community editing, but we want to get the foundation right first. Try it and share your feedback: github.com/orgs/OHF-Dev...

We have not settled on a final brand yet, so think of this as a working direction. The foundation is browse, search, and read. Every device gets a clear verdict on local control, cloud dependency, and support. No grades, just facts.

Still a bit surreal.. I’ll be speaking at the SOTOH26! At freaking TivoliVredenburg in Utrecht! Very excited to talk about the plans of the Open Home Foundation and how we as a community can make a real change. See you there, or follow it live on the streams.

Hooked my desk bike up to @home-assistant.io so now the office light gets brighter the harder I cycle. It’s basically an old school bike dynamo and makes me feel like a hamster. Currently being judged in lumens. 🚴💡

Made an important pull request today for @home-assistant.io 🙂 The Matter icon felt a bit off center because of the gravity effect. I moved it 1px higher and now it feels centered. Small change but it makes a difference. Before > After

I genuinely like iCloud: it’s easy to use, family photo sharing is great, and it keeps my local disks nice and clean. I just want a setup where I’m not relying on it as the only place my data lives. Curious how others here balance cloud convenience with local backups?

Matthias de Baat @matthiasdebaat.com · 23/01/2026
Experiment time 🧪 Just bought a NAS to experiment with local backups of my iCloud photos and documents. First test: Parachute Backup to pull everything down. So far, so good! Next experiment on the list: trying @immichapp.bsky.social for photo management 📸 Let’s see how far this setup can go.

I quite like it so far. Not sure if it’s worth the price over two PIR sensors in the same room. Btw, I’ve put the Matter code sticker inside the device.

Time to say farewell 2025 and hello 2026. 😌 It's because of you, the community, that we were able to make 2025 our best year yet. 👏🏻 From all of us, to you and yours: here's to all the blessings we hope 2026 will bring. 🥂 #HappyNewYear #SmartHome #HomeAutomation
A simple graphic of a stamp on a red background, created by our graphic artist Clelia Rella. The stamp has a beige border with a black background. Aligned to the bottom left of the stamp is the year 2026 stacked on itself in white text; from the bottom right branches out green sprigs of evergreen in the style of our antenna lines, it weaves through the numbers. Aligned to the top left in white is the Home Assistant logo and name. The red background has darker red shaded snowflakes with a few wavy lines aligned near the bottom left as if a postal carrier stamped an envelope the Home Assistant stamp is on. Under the stamp in white text reads: HAPPY NEW YEAR!
