The casambi dimming system is a Bluetooth-based smart lighting control system that provides a convenient and reliable lighting control solution.

By uniquely combining low-power communication with broad smartphone support, the casambi dimming system presents an intriguing alternative to other communication protocols like ZigBee and WiFi. It can also integrate with other technologies to make smart lighting even smarter.

The following sections will detail how casambi works and guide you through configuring LED light strips, helping you effortlessly create personalized lighting experiences.

What is the Casambi Dimming System?

The casambi dimming system is a Bluetooth-based smart lighting control system.

1. Device Configuration

The first step in setting up the casambi dimming system is installing and configuring the lights. Each light fixture requires a casambi module, which incorporates a Bluetooth chip and dimming circuitry. Once installed, the lights automatically form a Bluetooth network—the casambi network—enabling wireless control via the casambi app on a smartphone or tablet.

2. Network Establishment and Management

The casambi network operates as a peer-to-peer system where each light fixture can function as a signal relay node, expanding coverage. Users manage and control the network via the casambi app on their smart devices. This app scans nearby casambi networks, displays them on the device, and allows users to join selected networks.

3. Lighting Control Features

Users can control and adjust lighting via mobile phones or computers. Through the casambi app, users can individually control the brightness, color temperature, and color of each fixture. Additionally, users can create different lighting scenes and switch between them with a single tap to meet various needs.

4. Smart Control

The casambi dimming system is compatible with protocols like DALI and 0-10V, supporting smart features such as scheduled on/off, motion detection, and occupancy sensing. Users can schedule fixtures to turn on/off automatically at specific times or adjust brightness based on data from light sensors.

5. Compatibility and Scalability

The casambi dimming system supports system expansion and upgrades. Users can add more fixtures as needed and integrate them into the existing casambi network. Furthermore, casambi regularly releases system updates to introduce new features and enhance the user experience.

How to Control Your LED Strip Lights with Casambi?

LED 灯条 typically operate on 12V/24V DC power and require a dedicated driver for connection. The casambi controller communicates directly with the strip light driver via its Bluetooth 5.2 module.

Users can achieve seamless dimming (0-100% precision) for monochrome strips and precise control over 16 million colors for RGB strips using only a mobile app. The system features scene memory and scheduling for light strips, allowing preset configurations for up to 7 lighting scenes. A single gateway manages 250 nodes, covering 300㎡ without wiring. It supports compatibility with 0-10V, PWM, and DALI drivers. Its smart wireless approach simplifies efficient zone control for commercial spaces and home automation integration.

Below are common casambi device wiring connection methods for standard LED light strips, provided for reference!

1. Single-Color LED Strip Connection Method

Single-color strips support 0-10V/PWM dimming and high-voltage TRIAC dimming. When paired with 0-10V or PWM dimming power supplies, use a power supply with a built-in casambi dimming module. Adjust brightness and color via smartphone or controller, with 5 preset brightness scenes available.

2. Dual-Color LED Strip Connection Method

Dual-color strips also support 0-10V/PWM dimming using a dedicated dual-output power supply for color temperature adjustment. Connect the power supply to the casambi dimming module, ensuring compatibility with either common cathode or common anode wiring. Adjust the cool-to-warm light ratio (e.g., 3000K-6000K) or preset scene modes via the slider.

3.RGB/RGBW LED Strip Connection Method

Supports independent RGBW channel control with an RGB/RGBW controller. Each channel’s output current is individually adjustable (50-200mA), enabling 16 million colors precision adjustment across linear/logarithmic/optimized logarithmic modes.

Allows ±50% current adjustment per channel and divides strips into 4 independent control groups. Data exchange via Bluetooth GATT protocol. Core control commands include the following:

4. Networking Control Method

Compared to traditional DMX512 or PWM wired control solutions, casambi supports Bluetooth Mesh networking. A single gateway can connect over 250 devices, eliminating wiring hassles. Field tests demonstrate full signal coverage within 300㎡ commercial spaces.

Utilizing Bluetooth 5.2 protocol with anti-interference circuit design, the 2.4 GHz frequency hopping mechanism effectively avoids signal conflicts with WiFi and other devices. Full integration into the casambi ecosystem enables connection to casambi-compatible lighting fixtures. Configure sensor parameters and customize lighting sequences via the casambi app to flexibly build fully automated smart lighting scenarios.

Sensors can form interconnected networks. When motion triggers detection, lights within the group automatically illuminate. Precise detection of human respiration signals maintains constant illumination within the group. Upon departure, lighting automatically shuts off. Supports adaptive light control: automatically adjusts brightness based on ambient light levels, ensuring comfortable, consistent lighting around the clock.

The casambi smart system is a Bluetooth-based intelligent lighting control system, functioning as a “smart remote control” for your lights. For instance, while relaxing on the couch, adjust brightness with your phone. Forgot to turn off lights when leaving? Remotely switch them all off with one tap. Create diverse lighting scenes like “Coming Home,” “Entertaining,” or “Movie Night”—envision the hallway lights turning on automatically as you open the door, curtains opening, and music playing.

Casambi Installation Considerations

Casambi simplifies installation for efficient setup, which is why many choose it. It works by connecting lights to a wireless network, eliminating the need for new wiring and brackets while enabling quick configuration. Keep the following points in mind during installation:

• Bluetooth Signal Stability: Ensure the installation location is free from strong electromagnetic interference, such as large metal structures or high-voltage equipment. The effective Bluetooth range is ≤80 meters. If devices go offline, check if the router has enabled Bluetooth MAC filtering or try restarting the module.

• Power Compatibility: Fixtures must match the voltage specifications of the Casambi dimming module (e.g., 220V or low-voltage DC) to prevent overload or under-voltage operation.

• Wiring Method: For dual-color temperature strips with common cathode/common anode configurations, connect correctly to the module. Incorrect wiring may cause control failure. Use copper wire with a cross-sectional area ≥1.5 mm² and avoid excessive cable length (recommended ≤30 meters) to prevent signal attenuation.

• Grounding: Ground the module housing using a yellow-green dual-color wire (resistance ≤10Ω) to prevent electrostatic interference.

• Version Updates: Update the module to the latest version via the app to resolve known compatibility issues.

• Network Permissions: Grant the app Bluetooth and local network permissions during initial setup to ensure device discovery.

• Moisture and Dust Protection: For outdoor installations, select modules with IP65 or higher protection ratings. Apply sealing gaskets in humid environments.

• Heat Dissipation Design: Maintain ≥5 cm clearance around the module to prevent performance degradation from high temperatures (>60°C).

• Control Latency: Reduce the number of simultaneously connected devices (recommended ≤50) to optimize network load.

概括

The casambi dimming system enables intelligent lighting control and adjustment via Bluetooth technology. It offers not only convenient operation but also supports smart features and system expansion. This makes casambi one of the ideal choices for modern lighting control.

Whether for residential or commercial lighting, the casambi dimming system meets user needs. The evolution of casambi technology promises increasingly comfortable and personalized lighting experiences.
