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.

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

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.

The @openhomefoundation.org was at the CSA member meeting in Barcelona. Great to meet like-minded people building the best smart home. With privacy, choice and sustainability in mind. Exciting things ahead with @home-assistant.io!

Home Assistant community at its best. 😂 Q: “Can I check @home-assistant.io installs in my hometown?” A: “Sure… just declare independence first.” www.reddit.com/r/homeassist...
Screenshot of a Reddit post, where you see a map of San Marino and 19 installations. There is a comment thread where someone asks "That's neat, how can I check my own hometown?" And another user replies "Make it into a country".

This morning at 07:00, I was shocked to see it was already 27°C outside. Turns out, my neighbors placed an AC outdoor unit right next to my weather station. 😅 Looks like I accidentally have a @home-assistant.io sensor now that detects when my neighbor turns on their AC.
Screenshot of my weather station in Home Assistant thats shows a graph of a strong increase of temperature.

It’s a good thing Apple made Siri able to read your texts out loud, since reading seems to be out of the question

On my way to the Home Assistant Community Day in Utrecht, Netherlands. Judging by how full the train is, it’s going to be a busy and fun event! 🤣 #homeassistant #hacd2025

A bit of context. We want to add new triggers and conditions based on domains. User research showed that this is a valuable addition. At the same time, we observed that users often select a trigger based on a device (target). This is our latest design iteration. We would love to hear your feedback!

Installed the Nuki Smart Lock Pro 5 today. It’s an awesome lock! I’m amazed by the difference compared to the 4 Pro—it’s smaller, faster, and has great build quality. And of course, seamless integration with @home-assistant.io with to Matter over Thread.

I got this webcam mount for better “eye contact.” It attaches to the screen with a magnet, pretty wild! So far, I’m impressed. Curious to see how it performs during user interviews.
