LEDVANCE Just Put 116 Smart Lights Under Home Assistant's Roof. The Cloud Is No Longer Invited.

Your light bulbs should not need permission from a server in another country to turn on. That sounds obvious, but for a decade the smart home has run on exactly that arrangement: gadgets tethered to cloud accounts, one acquisition or bankruptcy away from becoming expensive plastic. This week, one of the world's largest lighting companies publicly chose the other side. LEDVANCE, the OSRAM spinoff that still sells smart lighting under the OSRAM brand, joined the Works with Home Assistant certification program with 116 Matter devices, one of the largest single lineups the program has ever admitted.

The announcement, published on Home Assistant's blog on October 13, covers nearly the whole of LEDVANCE's SMART+ consumer range: filament-style bulbs, spotlights, recessed and track downlights, ceiling and wall fixtures, floor lamps, and flexible LED strips, plus the SMART+ Plug and smart wall switches that fold ordinary fixtures into automations. Most of the range is tunable white or full color, and there are IP-rated options for bathrooms and gardens, including floodlights and outdoor spots.

Wi-Fi, not Thread: the pragmatic choice

Every certified device uses Matter over Wi-Fi, and that detail is deliberate. Thread is the mesh protocol of the moment, but it needs a border router: a smart speaker, a home hub, or some other device standing at the edge of the mesh. Wi-Fi needs only the router you already own. LEDVANCE's devices talk straight to Home Assistant's built-in Matter Server, with no proprietary hub, no extra border router, and no account to create.

The tradeoff is real. Wi-Fi devices draw more power than Thread devices, which is why battery-powered sensors still belong on Thread or Zigbee. But LEDVANCE's lineup is mostly mains-powered lighting, exactly the category where Wi-Fi makes sense. The message is pragmatic: interoperability without a shopping list of extra hardware.

The company itself is a study in old-world hardware meeting new-world standards. LEDVANCE was created in 2016 when OSRAM spun off its general lighting business, and its name is a portmanteau of LED and advance. Today it operates in more than 50 countries with customers in more than 140, carrying over a century of OSRAM's lighting heritage into the Matter era. When a company with that much installed credibility commits to open standards, it moves the market, not just the press cycle.

A certification that means more than "works with"

Here is the part that distinguishes this program from the average "compatible with" badge. To earn Works with Home Assistant status, a manufacturer must have its devices tested by Home Assistant's own team, commit to keeping them fully functional locally with no cloud dependency, and maintain that support long term. The bar exists because Matter certification alone does not guarantee any of it. The standard ensures devices speak the same language, not that every feature works on every platform, and not that the vendor will keep the local path open after the press release.

A light bulb that needs a cloud account is not a light bulb. It is a subscription you forgot you signed up for.

The cautionary tales are real, and LEDVANCE's own history provides one. OSRAM shut down the servers for its Lightify smart lighting platform in August 2021, and users of abandoned platforms know the pattern well: one sunsetting announcement and the hardware you bought starts losing features. Home Assistant's answer is architectural rather than legal. Since the certified devices don't need the manufacturer's cloud to function, a future server shutdown cannot turn them into e-waste. That is also the Open Home Foundation's sustainability argument, and it lands harder now, when the whole industry is trying to rebuild trust after years of bricked gadgets.

517 devices and counting

The certified device directory now stands at 517 devices, and the roster of recent partners tells its own story. Aqara, Eve, and Motionblinds preceded LEDVANCE into the program, and LEDVANCE has committed to certifying more products going forward. What is happening here is bigger than one brand. The open standard and the local-first community are converging into an actual ecosystem, one where a century-old lighting name can ship a bulb that works with any Matter platform and still earn a local-control badge.

It lands in the same week as the big platform-led launches, a reminder that the smart home is being built on two tracks at once. On one track, platform giants are packaging hardware into their ecosystems. On the other, the open-standard camp is betting that people want devices that outlive the platform. LEDVANCE just put its considerable weight on the second track.

For buyers, the practical takeaway is simple. The next time a bulb dies, the certified device directory is the short list worth checking: devices that speak Matter, work locally, and whose vendors have promised that they won't disappear on you. Lighting that keeps shining whatever happens to a platform should not be a luxury feature. As of this week, for 116 more products, it isn't.
