Casambi vs DALI is not a comparison between two technologies at exactly the same level. Casambi is a lighting-control platform that includes wireless communication, Casambi Mesh networking, commissioning tools, apps, device logic and integration options. DALI is a digital lighting communication protocol specified in the IEC 62386 series. DALI-2 is the certification program maintained by the DALI Alliance to verify compliance with the relevant specifications and improve multi-vendor interoperability. This article primarily compares Casambi Evolution wireless lighting control with conventional wired DALI-2 systems, while noting DALI+ as an important exception.

Short Answer

Casambi is usually the better fit when a project needs wireless retrofit, minimal new control wiring and frequent software-based rezoning. Conventional wired DALI-2 is usually the better fit when an IEC 62386-based bus, certified multi-vendor interoperability and standardized device communication are priorities. A hybrid system may be preferable when existing DALI infrastructure must be retained.

Quick Comparison Table

Are Casambi and DALI Directly Comparable?

The comparison is useful, but the scope has to be defined carefully. Casambi combines wireless communication, Casambi Mesh networking, apps, scenes, sensors, commissioning and integrations into one platform. DALI defines a standard language for digital lighting communication. The difference between the two is partly a difference between a complete platform and a protocol-based ecosystem.

For practical project decisions, the comparison is still valid because specifiers are often choosing between two control architectures: a wireless Casambi system or a conventional wired DALI-2 system. However, DALI should not be treated as permanently limited to wired transport. DALI+ carries DALI commands over wireless and IP-based networks such as Thread, Ethernet and Wi-Fi, even though this article focuses on the more common conventional wired DALI-2 case.

How Do Communication Methods Differ?

Casambi Mesh communication

Casambi uses its own proprietary BLE-based mesh technology, known as Casambi Mesh. It should not be confused with the Bluetooth SIG Bluetooth Mesh standard. Casambi states that Bluetooth Low Energy is used for communication between a mobile device or control interface and a Casambi network, while encrypted device-to-device communication inside the lighting network takes place through Casambi Mesh itself. The network is designed for local operation without a permanent internet connection, and normal lighting control does not require a central router.

Conventional wired DALI-2 communication

Conventional DALI-2 and D4i systems normally use a dedicated two-wire bus. The bus carries DALI communication and DALI bus power on the same pair of wires, but this should not be confused with the main operating power for the LED load. DALI bus power supplies the communication bus and connected control devices; LED drivers and luminaires still require their normal power connection. The DALI Alliance states that the wiring is polarity-insensitive, free wiring topology is allowed, the bus power supply is typically 16 V with up to 250 mA, and the maximum distance between the furthest-apart devices is 300 m.

Important exception: DALI+

Conventional wired DALI-2 is still the most common reference point, but DALI is no longer limited conceptually to wired communication. The DALI Alliance launched DALI+ to carry existing DALI commands over wireless and IP-based networks. That does not change the fact that most DALI comparisons in buildings still refer to the wired bus, but it prevents the article from turning “Casambi wireless, DALI wired” into an absolute rule.

How Do Architecture and Control Wiring Compare?

Casambi Evolution architecture

Casambi Evolution is built around a decentralized wireless mesh in which intelligence is distributed across nodes. Groups, scenes, schedules and sensor logic are defined in software. This can reduce or eliminate separate control wiring between switches, sensors and luminaires, which is why Casambi is often attractive in retrofit work. It does not eliminate power wiring, because luminaires, drivers and mains-powered nodes still need their normal electrical supply.

Conventional wired DALI-2 architecture

A conventional wired DALI-2 system is organized around control gear, application controllers, input devices and a bus power supply. The application controller and bus power supply do not always need to be separate products; they may be integrated into the same device. This architecture is often preferred when the project wants a structured wired topology, documented control panels and standardized communication between certified devices.

How Do Addressing, Groups and Scenes Compare?

Both platforms can support individual luminaire control, groups and scenes when the selected drivers, control modules and device profiles expose individual addressable channels. In DALI, control gear can be assigned short addresses, commands can be sent as individual, group or broadcast instructions, and each control gear device can store up to 16 scenes. In Casambi, individual control depends on the selected hardware profile and on whether the integration path preserves individual addressing.

This hardware condition matters in hybrid systems. For example, a Casambi-to-DALI integration can be configured for broadcast behavior in some cases, and then multiple DALI drivers respond together instead of as individually addressed luminaires. So the appropriate comparison is not simply whether one system supports single-fixture control, but under what hardware and configuration conditions that control is actually available.

How Do Commissioning and Future Changes Compare?

Casambi commissioning

Casambi commissioning usually involves discovering devices, adding them to a network, identifying luminaires, assigning controls, defining scenes and schedules, and confirming radio performance. Because relationships are software-defined, rezoning can be fast after handover. This is a major advantage in projects where occupancy patterns or layouts change frequently.

DALI commissioning

DALI commissioning usually includes confirming bus power and communication, discovering devices, assigning short addresses, identifying physical luminaires, creating groups and scenes, and testing controller logic and feedback. DALI is not inflexible; regrouping and recommissioning can be done in software as long as the devices remain on the bus. The main limitation is that the wired bus architecture must already be present and documented.

How Do Large Projects and Device Limits Compare?

Casambi network limits

A Casambi Evolution network can technically contain up to 250 devices, while a Classic network supports up to 127. Classic and Evolution devices are not mixed in the same network, and new projects should generally prioritize Evolution. However, the practical network size should be set by the selected network mode, device density, sensor traffic and future expansion needs rather than by the absolute technical maximum. Balanced mode is typically recommended for around 125 nodes, while Long Range is intended for smaller networks and only supports Long Range devices. This matters in Casambi vs DALI planning because node limits and scaling methods are not handled the same way in the two architectures.

Casambi Site structure

A Casambi Site provides site-level organization, access management and selected cross-network functions, but each underlying Casambi network remains a separate mesh network with its own device and performance limits. A Site does not merge several networks into one giant mesh beyond the per-network node limit.

DALI subnet limits

A DALI-2 subnet supports a maximum of 64 control gear addresses and 64 control-device addresses. Large projects scale by dividing the building into multiple DALI subnets and connecting them through higher-level controllers or building systems. This can be highly effective in large structured projects, but it also means more attention to line planning, control panels and documentation.

How Do Certification and Multi-Vendor Interoperability Compare?

Interoperability is one of the most important procurement issues in the Casambi vs DALI discussion. With DALI, the most reliable way to verify multi-vendor interoperability is to use DALI-2 certified products listed in the DALI Alliance public product database. A product described only as “DALI compatible” should not automatically be treated as DALI-2 certified.

With Casambi, the equivalent discipline is to prefer official Casambi Ready products or validated Casambi configurations. It is not enough to check for a compatible driver interface alone. The specifier should also confirm the fixture profile, firmware version, dimming channels, sensor functions and Evolution compatibility. In both ecosystems, product selection matters as much as the headline protocol name.

How Do Device Feedback and Diagnostics Compare?

DALI provides standardized two-way communication and device queries, but advanced luminaire, energy and diagnostics data should not be assumed for every DALI-2 driver. The DALI Alliance states that Parts 251, 252 and 253 are optional for DALI-2 certification and mandatory for D4i-certified LED drivers. So a project that specifically wants standardized luminaire, energy and diagnostics data should confirm whether it needs D4i rather than assuming all DALI-2 drivers expose the same data set.

Casambi should not be described as lacking diagnostics. Casambi networks can expose status and diagnostic information such as overheating, configuration problems or missing drivers, but the actual data available depends on the devices, profiles, firmware and integration path used. The most accurate comparison is that both ecosystems can provide useful feedback, but the scope and standardization of the data are hardware-dependent.

How Do Casambi and DALI Compare in Installation Cost and Total Cost of Ownership?

Cost is rarely decided by hardware price alone. Casambi can reduce the cost of control cabling, wall opening, ceiling work and disruption during retrofit, but the project still has to budget for wireless nodes, sensors, gateways where needed, commissioning labor and RF validation. DALI adds the cost of the bus, controllers and bus power supplies, but in new construction those elements can be designed into the project from the start.

Total cost of ownership depends on more than installation. Training, access permissions, system backups, configuration documentation, spare-parts strategy and the effort needed for future recommissioning all influence the long-term cost of the appropriate system.

When Does a Hybrid Lighting-Control Architecture Make Sense?

A. Casambi controlling wired DALI luminaires

Casambi can control wired DALI drivers through hardware such as Salvador-series devices and other Casambi control units, but the capabilities are product-specific. The number of connected drivers, whether control is individual or broadcast, and support for DT6 or DT8 can vary by device. That is why a hybrid lighting-control architecture must be specified at hardware level, not described as universal compatibility.

B. Wired DALI controllers presenting Casambi devices

Some gateway paths can present Casambi devices to a wired DALI control system. In that case, the available number of individually addressable devices, the use of broadcast mode and the exposed control objects depend on the gateway or translator path used. A wired DALI controller can therefore control Casambi devices in some designs, but only through a supported integration route with clearly defined limits.

C. Casambi wireless switches and sensors extending DALI systems

Casambi wireless sensors and switches can also be used to extend a DALI-based system through the right gateway path. This can be especially useful when the luminaires remain on a wired DALI backbone but user controls or sensor additions would be difficult to cable. Again, address counts, input instances and supported profiles are hardware-specific and must be verified during design.

Which System Should You Choose?

• Choose Casambi when the project is a retrofit, new control wiring would be disruptive, and future rezoning is likely.
• Choose conventional wired DALI-2 when the bus can be planned from the start, standardized certification matters, and the project wants a structured wired architecture.
• Choose a hybrid solution when useful DALI infrastructure already exists but wireless controls, phased renovation or flexible new zones must be added.

Project Scenarios

Existing office retrofit

Project condition: finished office floors, no appetite for new control cabling, and frequent space replanning. Recommended architecture: Casambi Evolution. Reason: software-based rezoning and wireless controls reduce disruption and make future changes easier.

New multi-floor commercial building

Project condition: new construction, DALI bus planned in advance, and procurement requires DALI-2 certified products and standardized device communication. Recommended architecture: conventional wired DALI-2 or D4i where advanced driver data is required. Reason: the wired bus and certification workflow fit structured commercial delivery.

Existing DALI warehouse with renovated zones

Project condition: an installed DALI backbone must remain, but renovated areas need new wireless controls and phased expansion. Recommended architecture: a Casambi–DALI hybrid system. Reason: it preserves the existing wired investment while adding flexibility in the updated zones.

Conclusion

Casambi and DALI are both serious professional lighting-control options, but they solve project requirements in different ways. Casambi Evolution is strongest where wireless deployment, reduced control cabling and rapid software changes create real project value. Conventional wired DALI-2 is strongest where a structured IEC 62386-based bus, certified interoperability and formal control documentation are priorities. In many real buildings, the best answer comes from matching the system architecture, device certification, integration path and maintenance plan to the project itself.

FAQ

Is Casambi better than DALI?

Not in every project. Casambi is often better for retrofit flexibility and wireless controls, while conventional wired DALI-2 is often better when a structured IEC 62386-based bus and certified multi-vendor interoperability are priorities.

Does Casambi use the Bluetooth Mesh standard?

No. Casambi uses its own proprietary BLE-based Casambi Mesh technology. It is BLE-based, but it should not be confused with the Bluetooth SIG Bluetooth Mesh standard.

Can DALI operate wirelessly?

Yes, in some cases. Conventional DALI-2 and D4i normally use a dedicated two-wire bus, but DALI+ carries DALI commands over wireless and IP-based networks such as Thread, Ethernet and Wi-Fi.

How many devices can Casambi and DALI support?

A Casambi Evolution network can technically support up to 250 devices, while a Classic network supports up to 127. A DALI-2 subnet supports a maximum of 64 control gear addresses and 64 control-device addresses. Large projects scale through multiple networks or subnets rather than one unlimited domain.

Can Casambi control individually addressed DALI drivers?

Yes, but only when the selected integration hardware and configuration support individual DALI addressing. Some hybrid paths may use broadcast behavior instead, which removes single-driver control.

Can a wired DALI controller control Casambi devices?

It can in some supported gateway or translator architectures, but not as a universal rule. The exact number of addressable devices, functions and limits depends on the hardware path used.

Does Casambi require a gateway?

Not for normal local mesh lighting control. However, remote access, cloud services, external BMS integration and some cross-network functions may require a gateway and internet connectivity.

What is the difference between DALI-2 and D4i?

DALI-2 is the broader certification program for compliant DALI products. D4i is a DALI-2-based certification class for intelligent luminaires and LED drivers with mandatory requirements for integrated bus power and standardized data such as Parts 251, 252 and 253.

Is Casambi or DALI better for retrofit projects?

Casambi is often the better fit for retrofit because it can reduce new control cabling and support fast software-based rezoning. DALI can still be a strong retrofit option if suitable bus wiring already exists or can be added without major disruption.

Can Casambi and DALI work together?

Yes, but through specific integration directions and hardware. Casambi can control wired DALI drivers, a wired DALI controller can sometimes access Casambi devices through a gateway path, and Casambi wireless controls can extend a DALI-based system. The limits depend on the selected products and profiles.
