Started to contribute to @home_assistant two weeks ago. What a refreshing community. Already made one friend (I hope) and the people over there so far are being super nice and friendly. Amazing culture @Frenck and folks created over there. ✨

🏠 Code is the easy part: Building Home Assistant in the open Looking forward to hearing @Frenck from @home_assistant on the work beyond code: governance, community, and building in public. There’s so much maintainer work that never shows up in a review or commit. reg.githubuniverse.com/flow/…

New in Claude Code: your sessions can now message each other. Instead of having to re-explain yourself in another session, you can now tell Claude to do it. It sends a summary (not your history or files), and the other session picks it up mid-task.

Some people still think Home Assistant automations mean YAML and a quiet evening to question your life choices. 😅 Nope! The new triggers and conditions let you start with what you want your home to react to. More power, less complexity! frenck.dev/more-power-less-c…

More power, less complexity in Home Assistant automations

The new triggers and conditions make Home Assistant automations more approachable, more powerful, and easier to extend without taking away the power underneath.

Open source won. That is why LGTM stopped being enough. In projects like Home Assistant, a PR is not just a diff. It can affect real homes, automations, and trust. Review got heavier because the stakes changed. frenck.dev/open-source-won-l…

Open source won. That is why LGTM stopped being enough

Open source became critical infrastructure. That success changed what pull request review means, especially for projects like Home Assistant that millions of households now depend on.

Home Assistant automation modes: why the default isn’t your friend. The default is `single`. Safe, but why some automations appear to ignore you. Learn how to pick the mode you need. 🙂 frenck.dev/automation-modes-…

Second newsletter is out! 🚀 RSS, YAML, Thread plumbing, old-web nostalgia, and the public confession that my Home Assistant setup has 294 devices and zero automations. Curious what people think when they open it from their inbox.

I’ve been quietly working on a new, extremely focused open-source project. The sensible part of me says: finish the tests and documentation first. The impatient part has already hovered over the publish button more than once. Soon™ 😀
