Casambi Lighting Controllers, Drivers, Sensors and Switches: Complete Guide

In this guide, “casambi lighting controller” is used as a broad practical term for a Casambi-enabled device that converts network commands into a usable lighting-control output. Drivers power LEDs, switches provide manual input, sensors provide automatic input, and gateways add remote access.

Device Roles at a Glance

What Is a Casambi Lighting Controller?

A casambi lighting controller is not one single official Casambi product category, but the phrase is still useful in specification work. In this article, the term is used as a practical umbrella expression for devices that join the Casambi network and produce a usable lighting-control output for a driver, luminaire, or electrical load.

That broad definition may include an integrated driver, a DALI interface, a 0–10V interface, a PWM unit, a relay controller, or a phase-cut dimmer. The device receives network commands and turns them into a usable control action.

What Are Casambi-Enabled LED Drivers?

A casambi LED driver combines LED power conversion and wireless control in one product. Instead of adding a separate casambi control module, the driver itself joins the network, receives commands, and adjusts the LED output.

There are two main electrical categories:

Constant-current drivers

These are commonly used with COB LEDs, LED boards, and luminaires designed around a defined current. A casambi LED driver in this category must be matched by output current, output-voltage range, power, dimming range, and thermal limits.

Constant-voltage drivers

These are commonly used for LED strips, linear modules, signage, decorative lighting, and other 12V, 24V, or 48V loads. Here, the designer must confirm voltage, wattage, current, cable voltage drop, and channel requirements.

Single-channel and multi-channel drivers

Typical configurations include one channel for single-color dimming, two channels for tunable white, three channels for RGB, and four channels for RGBW. However, actual channel assignment depends on the controller profile, LED load, and luminaire design. Additional channels may be required for RGBCCT, multi-white, or application-specific spectral control if the selected profile supports that channel mapping.

The main advantage of a casambi LED driver is fewer components, but matching and heat still matter.

How Do Casambi DALI and 0–10V Controllers Work?

A casambi wireless controller is often used when the luminaire already has a compatible wired driver, and a casambi wireless controller is especially useful in retrofit projects. Instead of replacing the driver, the controller translates network commands into DALI or analog dimming outputs.

DALI controller types

Casambi DALI devices should be separated into three different concepts:

Casambi’s CBU-ASD-LR is a good example of why this distinction matters. Its standalone DALI output does not comply with IEC 62386 and is not intended to be connected to an existing powered DALI network. It is a local closed-system control output, not a universal DALI bus controller.

Salvador products belong to the addressable DALI category. Depending on the Salvador series and model, the controller may support 16, 32, or up to 64 DALI driver addresses. Casambi officially lists SAL-2016, SAL-2032, and SAL-2064 in the Series 2000 family. Their purpose is to bring wired DALI drivers and luminaires into a Casambi system so that the DALI luminaires appear in Casambi as individually controllable luminaires. Address count, bus-power arrangement, physical format, and support for DALI switches or sensors must still be checked against the exact model.

0–10V and 1–10V controllers

A casambi wireless controller for analog dimming generates a control signal for a compatible driver. Although 0–10V and 1–10V are often grouped together, they are not always identical in minimum control voltage or driver behavior. Some drivers do not turn fully off at the minimum dimming signal.

That is why the specification should confirm whether the controller is sourcing or sinking, how much control current the driver requires, how many drivers can be connected, and whether full shutoff requires a relay. Casambi’s CBU-ARP-LR is especially relevant here because it combines a one-channel 0–10V output, a built-in 2 A relay, and a motion sensor input, and its control output can also be configured as DALI.

When Should PWM, Relay, and Phase-Cut Controllers Be Used?

These devices are not interchangeable.

PWM controllers

A casambi dimmer module based on PWM is normally installed between a DC power supply and a constant-voltage LED load, so a casambi dimmer module should not be confused with an LED power supply. Typical examples include LED strips, tunable-white tape, RGB/RGBW lighting, and constant-voltage linear modules. Casambi’s four-channel PWM products are intended for constant-voltage loads rather than constant-current LED modules.

Relay controllers

A relay-based casambi control module is mainly for switching non-dimmable loads or drivers that only need mains on/off control. When selecting one, the designer must check contact rating, load type, and LED-driver inrush current rather than checking only nominal wattage.

Phase-cut dimmers

A casambi dimmer module for phase-cut control modifies the AC waveform for compatible mains-dimmable loads such as dimmable LED lamps, some LED control gear, incandescent lamps, and halogen lamps. Casambi’s CBU-TED-LR is a trailing-edge dimmer, but published voltage and load ratings vary by product version, supply voltage, and load type. Casambi also states that CBU-TED-LR is available in UL and CE versions. In practice, compatibility cannot be judged only by a “dimmable” label; startup current, minimum load, low-end flicker, and actual dimming performance should be verified with the exact lamp or control gear.

What Types of Casambi Wireless Switches Are Available?

A casambi switch provides user input rather than LED power. It may be battery-powered, batteryless, mains-powered, or connected through a module that accepts conventional push buttons.

Battery-powered and batteryless switches

These are useful where new control wiring is undesirable. They can be used for on/off control, dimming, group selection, and scene recall. Some casambi controls devices harvest enough energy from the press itself to send a command.

Wall controllers and push-button interfaces

Some casambi controls devices provide a permanent wall interface, while others allow standard push buttons to be connected to an input-enabled module. In larger rooms, casambi controls may also be grouped by user function. That can preserve a familiar wall-switch format while moving the control logic into the network.

Casambi’s Xpress-LR is a well-known casambi switch for individual luminaires, groups, scenes, and animations. Casambi publishes a possible long-range reach of approximately 200 meters under favorable direct line-of-sight conditions. Actual indoor range depends on walls, metal structures, antenna orientation, installation height, and surrounding radio conditions. Node spacing in a real project should be based on network density and site testing, not on the theoretical best-case number.

How Do Casambi Motion and Daylight Sensors Work?

A casambi sensor provides automatic control input. Motion and occupancy sensors tell the system when people are present, while daylight sensors provide information about ambient light levels so the assigned luminaires, groups, or scenes can respond automatically.

Motion and occupancy sensing

A casambi sensor may use PIR, microwave, high-bay, or combined presence-detection technology. Selection should consider mounting height, detection pattern, sensitivity, environment, and whether the sensor is integrated, battery-powered, or externally powered.

Daylight-responsive sensing

Daylight sensors measure the light level at the sensor position, not directly at the task plane. That distinction matters because the control result depends heavily on sensor placement. In a Casambi system, daylight input can be used to dim assigned luminaires, groups, or scenes. This may support simple photocell on/off behavior, daylight harvesting, or more stable constant-light control depending on product capability and project setup.

For useful performance, the system usually needs a target light level, minimum dimming level, response speed, and calibration value. Installation position is critical. Sensors placed too close to windows, directly under bright luminaires, or near reflective and obstructed surfaces can produce misleading readings. In practice, good daylight control depends on mounting location and commissioning logic as much as on the sensor itself.

Sensor-only vs sensor-controller devices

Some casambi compatible devices only send sensor data into the network, while others combine sensing with a local control interface such as 0–10V, DALI, or relay behavior. When comparing casambi compatible devices, the designer should confirm exactly which role the device performs. The correct choice depends on whether the project needs a network sensor only or a combined local-control device. A casambi lighting controller must still match the load interface.

Which Casambi Device Should You Choose?

Common Casambi Device Selection Mistakes

• Treating a controller as if it were an LED power supply.
• Mixing up constant-current and constant-voltage loads.
• Assuming standalone DALI is the same as a full addressed DALI bus.
• Ignoring the fact that some 0–10V drivers do not switch fully off.
• Checking nominal load but not relay inrush current.
• Using theoretical wireless range as actual installation spacing.
• Hiding the module inside metal without checking antenna performance.
• Assuming Bluetooth support alone means Casambi Ready compatibility.

What Does Casambi Ready Mean?

Casambi Ready means the product has integrated Casambi technology and belongs to the Casambi ecosystem. It does not simply mean the device uses Bluetooth. A generic Bluetooth or Bluetooth Mesh product is not automatically a Casambi product. Casambi also states that its native products and partner Casambi Ready products are intended to work together within the ecosystem, but the designer must still check profile, firmware, network mode, and feature support.

What Does a Casambi Cloud Gateway Do?

A casambi gateway is a remote-access and cloud-connectivity device, not a local dimming output controller. According to Casambi’s official product information, the Casambi Cloud Gateway supports real-time remote monitoring and control over the internet, offers Ethernet and Wi-Fi connectivity, and should be used as one gateway per Casambi network. Casambi also states that it works with Evolution firmware only, so cloud-related capability should not be assumed to be identical across all network modes.

How Should You Match the Device to the Luminaire?

Start with the load and driver interface, then select the Casambi device that produces the required output.

Use an integrated casambi LED driver for a new luminaire when electrical and thermal conditions are already matched. Where that is not practical, an external casambi control module may be the better route. Use an external casambi control module when retaining an existing driver or load, especially when the project needs interface conversion rather than a full driver replacement. Add a casambi switch for manual input, a casambi sensor for automatic input, and a casambi gateway only when remote or cloud-connected functions are required. In multi-site projects, each casambi gateway should still follow Casambi network rules.

Quick Specification Notes

For many projects, the fastest path is to identify the load first and then decide which casambi lighting controller category fits that load. In retrofit work, a casambi lighting controller usually preserves the existing driver or load interface. In new luminaire development, a casambi lighting controller may instead be built into the product.

A casambi control module is often preferred where the driver already exists and only the control interface needs to change. Likewise, a casambi switch and a casambi sensor should be selected by user function and control logic.

When comparing casambi compatible devices, specifiers should distinguish between Casambi native products and partner products in the Casambi Ready ecosystem. Not every casambi compatible devices listing offers the same profile or approvals. A casambi wireless controller, a casambi dimmer module, and a casambi gateway each solve different problems.

FAQ

Does every Casambi controller also power the LED load?

No. Many controllers only output a control signal. The LED load is still powered by a separate driver.

Can a Casambi controller work with any DALI driver?

Not automatically. The project must confirm DALI mode, bus power, device type, addressing method, and support for DT6, DT8, or D4i where required.

Can a 0–10V Casambi controller turn the driver completely off?

Not always. Some drivers do not fully switch off at the minimum analog dimming level, so a relay output may be required.

Can a Casambi PWM controller drive constant-current LEDs directly?

Usually no. PWM controllers are typically intended for compatible constant-voltage LED loads.

Do all Casambi devices work with Classic and Evolution networks?

That should not be assumed. Specific products and cloud-related functions may depend on the selected network mode and firmware generation.

Can Casambi devices be installed inside a metal luminaire?

They can be integrated, but antenna position, metal shielding, temperature, and real communication performance must be evaluated.

Conclusion

Start with the load and driver interface, then choose the Casambi device that produces the required control output. That is the safest way to specify a casambi lighting controller. Use an integrated driver for a new luminaire when electrical and thermal conditions are already matched. Use an external DALI, 0–10V, PWM, relay, or phase-cut device when retaining an existing driver or load. Add manual and automatic input devices only as needed, and use a gateway only when remote or cloud-connected functions are required.
