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, not which trigger type fits... More power, less complexity!
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 pull request is not just a diff. It can affect real homes, personal data, and trust. Review got heavier because the stakes changed.
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 mode is “single”. Safe, backwards-compatible, and why automations can appear to ignore you. Learn how to pick the mode you need 🙂

What should happen when an automation triggers again before it is done? Pick the right Home Assistant automation mode deliberately.

Woke up with a random brain wave and had to check if I was right. My Saturday morning. 😄 Tiny Home Assistant PR: less wasted work in a hot template rendering path. Benchmark on my machine: about 51% faster. 🚀 Nice way to start the weekend. 🍻
Skip literal_eval for template results that cannot be a Python literal by frenck · Pull Request #173664 · home-assistant/core
Proposed change The result of a template render is coerced into a Python value via ast.literal_eval, memoized with @lru_cache(maxsize=EVAL_CACHE_SIZE) in _cached_parse_result. However, lru_cache o...

My second newsletter just went out. 🚀 This one has RSS, YAML, Thread plumbing, old-web nostalgia, and the slightly uncomfortable 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 working on something new. Presenting YAMLRocks 🪨 A fast, correct YAML library for Python, written in Rust. YAML 1.2 (and 1.1), safe by default, and round-trip editing that keeps comments, anchors, and formatting intact. #OpenSource

My first personal newsletter shipped. The next one is already slowly forming from links, notes, and things I did not want to lose in a browser tab forever. If you want one from the next batch, subscribe here: frenck.dev/newsletter/
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™ 😀
Home Assistant just added the Reolink Elite Floodlight WiFi and Trackmix WiFi to Works with Home Assistant. Reolink now has 10 certified cameras. That matches my setup: local, reliable, and excellent with Home Assistant.

A smart home will not save the planet
A smart home is not magic sustainability dust. The useful part is measurement, local control, and keeping good devices useful longer.

First newsletter went out Friday. Subscribers got it first, but I made this one public too so you can see what kind of thing it is. Mostly notes, links, thoughts, and a drawer being slightly less full. Read it here: frenck.dev/email/e333f2...
AI did not create the maintainer burden problem in open source. It accelerated it. Contributors are being amplified. Maintainers are still the verification bottleneck. New post: frenck.dev/open-source-...
Smoke and CO alarms are not the flashy part of a smart home. Good. They should quietly work, connect locally, and not become another app island. Nice to see Sensereo join Works with Home Assistant. www.home-assistant.io/blog/2026/05...
First newsletter sent. 🚀 I’m genuinely proud of that one. Not because it is perfect, but because I actually shipped it. If it landed in your inbox, I’d love to hear what you think. What worked, what didn’t, what you want more of. Now I’m going to pretend I’m calm and normal about this.
I’m publishing my first newsletter this Friday. It will be a more personal place for Home Assistant, open source, and the local-first smart home thoughts that don’t always fit into a post. If that sounds useful, you can subscribe here: frenck.dev/newsletter/
Developer machines are not production, but they often hold keys to production-shaped doors. Editors, extensions, CLIs, and local credentials are part of the supply chain now. That is uncomfortable. Also true. frenck.dev/your-editor-...
NFC tags sound boring until you use them. A cheap sticker becomes a Home Assistant trigger. No app hunting. No voice command. Just tap, and let the home do the thing. www.howtogeek.com/home-assista...
On my way to Utrecht to prepare for the State of the Open Home 2026! The Dutch railroad 🚂 in the mean time be like: safe travels and enjoy the view… 🧽🧼 🙈 #ns #trains #roflpimplmao
Templating has felt like homework for too long in Home Assistant. I reworked the docs on @home-assistant.io with one goal: make them more approachable. Every function has its own page now, with real examples! First pass, feedback welcome 🙏 www.home-assistant.io/docs/templat...
Just moved into a place with a garden. 60-70m2 of lawn I am not touching by hand. 🤪 Looking for a robot lawnmower for a small space that works with Home Assistant. Everything I find is sized for a castle. Recommendations? Manufacturers? Anyone? 🌿
