BEGA, a German firm with more than 75 years designing architectural lighting, is bringing its BEGA Smart Zigbee-powered lighting system into Home Assistant. The company describes BEGA Smart as flexible, expandable, and capable of operating offline without an internet connection, a selling point that could dramatically simplify smart lighting setups for high-end projects. This marks what the Home Assistant team calls one of the largest single additions of certified devices in the program, a development that could broaden the open ecosystem for architects, designers, and homeowners alike.

Ubisys, founded in Düsseldorf in 2005, adds a complementary emphasis on retrofit devices that help modernize existing homes rather than require a full replacement. The company backs its hardware with a five-year warranty and long software updates, a combination that resonates with sustainability and longevity goals. Ubisys stresses Zigbee as the backbone of its products, designed to run a local mesh network with no cloud dependency and optimized for long battery life, a workflow that dovetails with Home Assistant’s emphasis on local control. These traits align closely with the Open Home Foundation’s sustainability principles, a point the company highlights in its broader mission.

The practical implications of this double enrollment are meaningful for real homes. Zigbee’s mesh network means devices can relay signals to extend coverage without overloading a single hub, a factor Ubisys frames as essential for retrofit work that often spans awkward floor plans and older wiring. Meanwhile BEGA’s offline-capable lighting system highlights a growing segment of smart home tech that can function without continuous internet access, reducing dependency on cloud services and improving resilience during outages. For homes already built around Home Assistant, the combination of long-term firmware support from Ubisys and the expanding roster of certified, interoperable lighting options from BEGA sharpens the case for investing in an open, local-first smart lighting strategy. ubisys joins BEGA joins

Practitioner takeaways are clear. First, retrofit projects get a powerful ally in Ubisys, offering durable hardware and ongoing updates that keep older installations relevant longer, backed by a substantial warranty. Second, BEGA’s offline capable lighting eases management for complex facades, hotels, and public buildings where stable, local control can be a priority. Third, the expanded catalog reduces compatibility friction for Home Assistant users who want a cohesive, Zigbee-based ecosystem without migrating to cloud-dependent solutions. Finally, expect continued emphasis on longevity and open standards, suggesting more established lighting and retrofit brands will pursue Works with Home Assistant certification to reach the growing community’s demand for reliable, local-first automation. ubisys joins BEGA joins

Verdict: Buy if you want stronger offline capability and longer-lasting Zigbee devices that integrate smoothly with Home Assistant, especially for retrofit projects or high-end lighting installations. If you mainly rely on cloud features or already have a full smart home, these additions are a thoughtful upgrade rather than a replacement for your existing setup. BEGA joins ubisys joins
