Thanks to its Bluetooth Low Energy connectivity, the CBU-4P transforms wired pushbuttons into wireless control interfaces within a Casambi network.
Its compact design and ease of installation make it an ideal solution for lighting automation projects in homes, offices, hotels, or commercial spaces.
Advanced control from traditional pushbuttons.
The CBU-4P features four independent inputs for normally open (NO) pushbuttons, allowing control of different luminaires, lighting groups, or scenes within a Casambi network. Each input can be configured to perform different actions, such as:
• Turning luminaires on or off
• Dimming the lighting intensity
• Activating pre-configured scenes
• Controlling groups of luminaires within the network.
This allows the use of conventional wall switches without modifying existing wiring, facilitating the transition to smart lighting systems.
Full integration into the Casambi ecosystem.
The module communicates via Bluetooth Low Energy (BLE) and uses the Casambi protocol to integrate into wireless lighting control networks. All configuration is done through the Casambi app, available for smartphones and tablets, which allows you to:
• Create scenes and groups
• Schedule timers
• Adjust the behavior of each button
• Manage the installation centrally.
Furthermore, the system allows for remote firmware updates via OTA (Over-The-Air) updates, facilitating maintenance and upgrades within the installation.
Versatility in power supply and ease of installation
The CBU-4P supports three types of power supply, providing great versatility in different types of projects:
• 110-240Vac
• 24Vdc
• 12Vdc
Its compact format allows it to be installed in electrical boxes or junction boxes, integrating discreetly into the infrastructure without altering the aesthetics of the space.
