BEGA and ubisys join Works with Home Assistant

Two German lighting makers are expanding the Works with Home Assistant certified devices, signaling a broader push to add durable, offline capable Zigbee hardware to the open ecosystem. BEGA joins the program bringing BEGA Smart Zigbee lighting to Home Assistant and marking the largest single addition of certified devices to date [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/].

BEGA describes BEGA Smart as a Zigbee powered system designed to work entirely offline, a feature that matters for homes where the internet wanders or where privacy minded customers prefer local control. The company also notes the product line is built on more than 75 years of architectural lighting design, underscoring that smart features are paired with a long track record of durability [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/]. Heinrich Gantenbrink, Managing Partner, framed the collaboration as a way to blend high quality lighting with intelligent, flexible control within Home Assistant’s ecosystem, aiming to boost comfort, safety and energy efficiency for users [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/].

On the same day, ubisys joined the Works with Home Assistant program, adding a second wave of Zigbee devices designed to retrofit existing homes rather than requiring a full systems overhaul. Ubisys, founded in Düsseldorf in 2005, brings more than 20 years of smart home automation experience and backs its hardware with a five-year warranty and ongoing software updates, a commitment that aligns with the Open Home Foundation’s sustainability ethos [https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/]. Ubisys emphasizes Zigbee as the backbone of its products, describing the protocol as a mesh network that runs locally, with nodes talking to a central Home Assistant hub and to each other, all without cloud dependency and with an eye toward long battery life [https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/].

The dual rollout signals a broader push by Home Assistant to expand the catalog with durable, offline capable Zigbee hardware that works across households built with older gear. Practically, that means users with mixed device ecosystems can add certified products without surrendering local control or inviting constant cloud calls, a common friction point for many smart homes [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/][https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/]. This matters for retrofits, where upgrading a single fixture or switch can ripple through an existing setup without reconfiguring a hub or re-architecting the network [https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/].

Practitioner insights emerge from the details of these moves. First, offline operation is not just a curiosity; it translates into more resilient homes that shrug off WiFi hiccups and ISP outages while still delivering reliable automation. BEGA’s offline Zigbee approach embodies that principle, and ubisys frames Zigbee as a long term backbone that can outlast faddier cloud features [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/][https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/]. Second, the five year warranty and ongoing software updates are non-trivial in the retrofit market, where devices can outlive the user and the initial installation. Ubisys’ longevity stance and BEGA’s long heritage both reflect a performance standard that buyers should weigh against cheaper, shorter lived options [https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/][https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/]. Third, the emphasis on Zigbee as the communication backbone highlights a deliberate shift toward local control over cloud dependencies, a trend that many power users and sustainability minded households will welcome as grids and data use become more scrutinized [https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/].

The pairing of BEGA and ubisys with Works with Home Assistant also hints at a future where high design and practical retrofit capability coexist in a single, open ecosystem. As more manufacturers lean into longevity, offline operation and transparent warranties, users gain a clearer path to upgrade without ripping out existing infrastructure. The two brands’ launches echo an industry push toward durable hardware that remains relevant through software updates and local control, rather than a transient wave of cloud tied devices [https://www.home-assistant.io/blog/2026/05/05/bega-joins-works-with-home-assistant/][https://www.home-assistant.io/blog/2026/04/23/ubisys-joins-works-with-home-assistant/].

Buy, wait or skip? If you prize retrofit ready, offline capable lighting with strong warranties and long term software updates, this is a buy. If you are perfectly happy with cloud reliant devices or you’re not upgrading your lighting soon, you might wait to see how other manufacturers respond in the coming months. Either way, the trend is clear: local control is no longer a secondary feature, but a central selling point in smart home lighting.
