Casambi integration ​

Casambi is a Bluetooth-mesh lighting-control standard used across the architectural lighting industry. Hundreds of luminaire manufacturers ship Casambi-enabled fixtures or Casambi-compatible drivers — including Flos, Occhio, Delta Light, Zumtobel and Luceplan among many others (see the full list at casambi.com/partner-directory).

With an Atios SmartCore or Atios KNX Bridge, plus a Casambi CBU-DCS, you can bridge any Casambi installation into Apple Home, Google Home, Alexa, or SmartThings via Matter.

How it works ​

Your Atios device (SmartCore or KNX Bridge) acts as the DALI Master on its DALI bus. The CBU-DCS — Casambi's Bluetooth-enabled DALI controller — sits on that same bus and translates DALI commands into Casambi mesh messages that reach each luminaire wirelessly.

Luminaires

You can mix Casambi-bridged luminaires and hard-wired DALI lights on the same Atios device. Hard-wired DALI lights connect directly to the DALI port — no CBU-DCS needed for those.

What you can control ​

Once paired, your Casambi lights become standard Matter accessories. You get:

  • On / off and dim to any brightness level
  • Colour control for tunable white (DT8) and RGB fixtures
  • Scenes and automations in your smart home app
  • Siri / Google Assistant / Alexa voice commands
  • Remote control when you're away from home
  • Brand-specific extras where the fixture supports them (for example, height adjustment on motorised Occhio fixtures)

Known limitation ​

Up/down fading is not supported

When routing through a Casambi DALI gateway, the up/down fading command is not available. Step dimming and target-brightness commands work normally.

What you need ​

  • An Atios SmartCore or Atios KNX Bridge
  • A Casambi CBU-DCS DALI gateway (one or more, depending on your installation)
  • Your Casambi-enabled luminaires (any brand)
  • A Matter-compatible hub (Apple HomePod, Google Nest Hub, Amazon Echo, or SmartThings Station)

About the CBU-DCS ​

The CBU-DCS is powered directly from the DALI bus — no separate power supply is needed. It supports DALI Device Type 6 and Type 8, including tunable white and RGB. Each CBU-DCS counts as 3 DALI loads.

See Casambi's CBU-DCS product page for the datasheet. Casambi also offers other DALI controllers (Salvador Series 1000/2000/3000) and a KNX hybrid gateway (CGW-KNX) — these work on the same principle.

Firmware requirement

The CBU-DCS's DALI gateway function only works with Casambi Evolution firmware. Update your Casambi network before setup if needed.

Setting it up ​

  1. Install SmartCore and power the DALI bus — see SmartCore Mounting.
  2. Connect the CBU-DCS to SmartCore's DALI bus.
  3. Pair the Casambi luminaires to the CBU-DCS using the Casambi App.
  4. In SmartCore's Web Interface, run the DALI Configurator to discover the DALI addresses exposed by the CBU-DCS.
  5. Add the DALI lights in the Accessory Manager.
  6. Scan the Matter QR code with your chosen app.
