Smart Stair Lighting with Step-by-Step and RGB Side Flow Effects The MALIIGAZA MS032B is an intelligent indoor stair light controller designed for up to 32 steps. It combines motion-activated step lighting with optional RGB addressable side lighting, Tuya app control, voice control, adjustable dynamic effects, and optional MESH wireless accessories. Turn an Ordinary Staircase into a Smarter Lighting Experience Light each stair progressively as you move, while an optional RGB SPI strip along the handrail or wall creates a synchronized flowing light effect. With two PIR motion sensors, the system can automatically detect whether you approach from the bottom or top of the staircase and start the lighting sequence from the corresponding direction. Key Benefits ✓ Up to 32 Steps Supports staircases with up to 32 individually controlled step-light outputs. ✓ Dual Direction PIR Detection Two PIR sensors detect movement from the top or bottom and trigger the lighting sequence in the correct direction. ✓ RGB Side Flow Lighting Add compatible RGB addressable SPI strips to a handrail or wall for flowing color effects alongside the stair lights. ✓ Tuya App Control Connect through Bluetooth to the Tuya app for convenient smart lighting control and adjustment. ✓ Voice Control Support Compatible with Alexa and Google Home for voice control in a compatible Tuya smart-home configuration. ✓ Flexible Dynamic Effects Choose from 9 dynamic modes and adjust lighting speed, step behavior, illumination time, and timer settings. Step Lighting + RGB Side Flow in One Controller MS032B can control two different lighting areas at the same time. Step lighting: Supports compatible 12V or 24V single-color LED strips. Side flow lighting: Supports compatible 12V or 24V RGB addressable SPI LED strips for dynamic flowing color effects. When activated, the stair lights can illuminate progressively while the RGB strip installed along a handrail, staircase edge, or adjacent wall creates a synchronized flowing effect. Motion Activated from Both Directions Two PIR motion sensors are used for intelligent staircase detection. Bottom Sensor When movement is detected at the bottom, the lighting sequence starts from the lower stairs and moves upward. Top Sensor When movement is detected at the top, the lighting sequence starts from the upper stairs and moves downward. 9 Dynamic Lighting Modes Customize how your staircase responds instead of being limited to a simple on/off effect. Choose from 9 different dynamic modes. Set step-by-step illumination. Configure multi-step lighting effects. Adjust animation speed. Adjust how long the lights remain illuminated. Use timer settings to manage operating periods. Tuya Smart Home Control Connect the controller to the Tuya app through Bluetooth for convenient control and lighting adjustments. The controller also supports Alexa and Google Home voice control when configured within a compatible Tuya smart-home environment. Optional MESH wireless panel switches and MESH wireless motion sensors can also be selected for expanded control options. Important: No Built-In Daylight Sensor MS032B does not detect ambient brightness. If you do not want the stair lighting to operate during daytime hours, use the timer function to define the desired operating period. Convenient Push-In Wiring Terminals The controller uses press-type terminal connections designed to make inserting and removing compatible wiring easier during installation, adjustment, or maintenance. Ideal for Indoor Stair Lighting Projects Home Staircases Create automatic lighting for everyday indoor stairs. DIY Lighting Projects Build a customized step-lighting layout around your staircase.

Please check the exact variant selected before ordering. The base controller option does not include LED strips, power supply, wireless sensor, or wireless panel switch unless those items are specifically listed in the selected package. Installation Guide Choose the correct DC system voltage. Use a 12V system with 12V LED strips, or a 24V system with 24V LED strips. Connect a suitable DC power supply. The controller must receive DC 12V or DC 24V power. Never connect it directly to AC mains voltage. Connect the step lights. Install compatible single-color 12V or 24V strips on the required stair outputs. Install the PIR sensors. Position one sensor at the bottom and one at the top of the staircase for directional triggering. Connect the optional RGB side-flow strip. Use only a compatible 12V or 24V RGB addressable SPI strip for the flowing side-light effect. Set the RGB pixel quantity correctly. If an addressable side strip is installed, configure the pixel number to match the actual number of pixels on the strip. Configure the lighting behavior. Select the desired dynamic mode, animation speed, lighting duration, and timer settings. Troubleshooting Guide Controller does not power on Confirm that the controller is connected to a suitable DC 12V or DC 24V power supply and that the power supply voltage matches the lighting system. RGB side-flow strip does not work Confirm that the side strip is an RGB addressable SPI LED strip. A standard single-color strip cannot provide the addressable flowing effect. RGB lighting stops at the wrong position Check the pixel-number setting and make sure it matches the actual number of addressable pixels in the installed RGB SPI strip. System operates during daytime This model has no built-in daylight sensor. Use the timer function if you want to prevent operation during selected daytime hours. Lighting starts from the wrong direction Check the installation and position of the top and bottom PIR sensors so that each sensor corresponds to the intended staircase direction. Important Safety and Compatibility Notes DC 12V / 24V only: Never connect the controller directly to AC 220V mains power. Direct AC connection can immediately damage the controller. Match system voltage: A 12V LED strip must be used with a 12V power supply. A 24V LED strip must be used with a 24V power supply. RGB side-flow requirement: Dynamic side lighting supports compatible RGB addressable SPI strips only. It does not support single-color strips for addressable flowing effects. Indoor use: The controller is not waterproof and is designed for indoor stair-lighting installations. Check your package: LED strips, power supply, wireless sensors, and wireless switches are not included with the base controller unless specifically included in the selected product variant. Pixel configuration: When using an RGB addressable strip, set the controller pixel number to match the actual strip pixel quantity for accurate lighting control.
