It presents anonymous, aggregated data contributed voluntarily by users and supports browsing, searching, and filtering devices by characteristics such as internet requirements, protocols, and integrations. The preview is intentionally limited and unpolished, with community feedback helping shape its later official launch. ### Source excerpt Ever since we introduced the idea of a community-powered device database at State of the Open Home 2025, our goal has been clear: create a "Wikipedia of smart home devices" based on real-world usage. In February, we took the first step by inviting Home Assistant users to voluntarily share anonymized device data to help us build it. ## zunzunbee joins Works with Home Assistant DevFeed: [zunzunbee joins Works with Home Assistant]() Original publisher: [Read original article]() Author: Miranda Bishop Published: 2026-05-19T00:00:01Z Content type: article Language: en Sources: [Home Assistant]() Topics: [Home Assistant](), [Automation](), [systems]() Tags: [2026](), [automation](), [battery](), [complexity](), [cost](), [devices](), [homes](), [installation](), [lighting](), [local](), [product](), [smart](), [smart-home](), [works-with-home-assistant]() ### AI overview Home Assistant announces that zunzunbee has joined its Works with Home Assistant program. The company's Slate Switch is a battery-powered smart scene controller that snaps over existing switches, supports tactile local control, and can be used as a portable remote. It is designed to simplify smart-home installation while keeping smart bulbs powered and preserving automations. ### Source excerpt We are often asked if we prioritize "Big Tech" firms in the Works with program, but we've always been clear that newer companies are just as important to our certification as household names. Start-ups are innovators, and have their fingers on the pulse of community needs much more than brands that are only at the mercy of their investors. That's just one reason we're thrilled to welcome zunzunbee to the program! They really stood out from the crowd at CES 2026 this January with their new product, the Slate Switch. This battery-powered smart scene controller simply snaps over existing switches - ideal if you rent your home, or don't fancy working with wiring. We're always on the lookout for devices that make setting up your smart home easier, so we're delighted to have zunzunbee on board! A clean slate for switches While zunzunbee are newcomers to the market, founder Harish Raman has more than 18 years' experience in lighting and connected systems - including senior engineering roles at Leviton and Philips. Harish designed the Slate Switch to cut the complexity sometimes found in smart homes, by bringing back simple, tactile control without any installation headaches. And because it builds on top of your existing switches rather than replacing them, it means less waste and more value from the things you already own. "At zunzunbee, we believe smart home control should feel natural, reliable, and stay under the user's control. The Home Assistant community shares that same philosophy, with a focus on local control, flexibility, and deep customization. Slate Switch was designed to solve everyday friction in smart homes, and we are excited to bring it to a community that values thoughtful automation and truly understands how homes should work." - Harish Raman, Founder Not just for newbies The Slate Switch isn't just a low-barrier entry point for beginners. It also tackles an issue that can crop up in more complex smart home setups: someone flipping a wall switch that con ## BEGA joins Works with Home Assistant DevFeed: [BEGA joins Works with Home Assistant]() Original publisher: [Read original article]() Author: Miranda Bishop Published: 2026-05-05T00:00:01Z Content type: news Language: en Sources: [Home Assistant]() Topics: [Home Assistant]() Tags: [community](), [devices](), [ecosystem](), [energy](), [offline](), [safety](), [smart](), [smart-home](), [sustainability](), [tech](), [works-with-home-assistant]() ### AI overview BEGA has joined the Works with Home Assistant program, bringing a large portfolio of certified architectural lighting products.

It introduces blktrace and related tools for capturing detailed disk I/O traces, then using blkparse to analyze them and identify process-level or time-sensitive performance issues. ### Source excerpt Beyond iostat: Storage performance analysis with blktrace An under appreciated set of IO analysis tools. If you've spent much time at all investigating IO performance on Linux, you're no doubt already familiar with iostat from the venerable sysstat package. iostat is the go-to tool for Linux storage performance monitoring with good reason: it's available nearly everywhere, it works on the vast majority of Linux machines, and it's relatively easy to use and understand. Some of what it measures can be subtle, and the exact definitions of its measurements can be confusing, and even contentious, but it's still a great start. Sometimes, though, you need to go into more detail than iostat can provide. The aggregate view from iostat is simple, but makes it difficult to tell which processes are doing which IOs. Averaging over a period of time can hide subtle performance issues and the real causes of may IO-related problems. To get around these issues, you'll want to go deeper. If you have the guts for it, a recent kernel, and a good understanding of IO performance issues, you'll want to reach for blktrace and friends. The blktrace toolkit provides an extremely powerful way to look at the exact IO performance of a Linux machine, at a wide range of levels of detail, and is vastly more capable than the simple iostat. For a start, let's look at the performance of a random read workload to a magnetic drive, with 16k IOs. The manufacturer's spec sheet says this drive should be delivering about 120 IOs per second on a completely random load. iostat -x has this to say about the drive: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz sdb 0.00 0.00 124.67 0.00 3989.33 0.00 32.00 avgqu-sz await svctm %util 1.00 8.01 8.02 100.00 As expected, we're doing about 125 random IOs per second, each at 16k (32.00 512 byte sectors), at a mean service time of around 8ms. That's pretty much exactly what we would expect from a 7200 RPM magnetic drive. Nothing to see there, then. Next up, is a d ## Linux - naprawianie bad sectorów DevFeed: [Linux - naprawianie bad sectorów]() Original publisher: [Read original article]() Author: Tom Published: 2012-12-27T00:00:00Z Content type: tutorial Language: pl Sources: [Tomasz Gągor]() Topics: [Linux]() Tags: [badblocks](), [bash](), [linux](), [smart]() ### AI overview A Linux disk with bad sectors is tested using non-destructive badblocks scans and SMART tests. The SMART results identify the first problematic sector, allowing badblocks to be started from that location or from the beginning of the disk. ### Source excerpt Dyski się zużywają i w końcu wcześniej czy później pojawiają się na nich bad sectory.
