An Automated Trellis Shade Control System is becoming increasingly popular in Singapore due to the city’s hot climate, strong sunlight, and frequent sudden rain. These systems feature a smart roof structure—typically built with aluminium louvers or retractable fabric—that can open or close automatically depending on weather conditions.

How the System Works
The trellis is powered by a motorised mechanism that allows the louvres or fabric panels to turn open for ventilation or sunlight and close completely for protection. When the system is in the sun shade position, it reduces heat gain on balconies, patios, and rooftop terraces.
Because the system is automated, it can operate on its own without user input. Sensors monitor environmental conditions, and the trellis will auto-close when rain is detected. This is especially useful in Singapore, where showers often come unexpectedly. At the same time, the roof can open automatically when conditions are safe, allowing airflow and natural daylight.
Trellis is an alternative to an awning for those who prefer a solid structure that can withstand wind and rain.
Key Features
- Automated open/close control through remote, wall switch, or mobile app
- Weather sensors that trigger auto-close when it rains
- Adjustable louvre angles that let users turn open the roof partially or fully
- Effective sun shade during peak afternoon heat
- Strong, durable structure suitable for tropical climates
Why It’s Ideal for Singapore
Outdoor living spaces in Singapore—from HDB balconies to landed patios—benefit greatly from flexible weather control. An automated trellis enhances comfort by blocking heat, keeping areas dry, and providing a reliable shade solution that adapts instantly to changing skies.

Trellis Single-Bay Control Board
Single-Bay Trellis control board from
Sunshade Trellis System Pte. Ltd. (Singapore)
This control board provides the control for a single bay roof Trellis system. It can be identified from the 3 switches user control wall-switch.
The top button is a rain sensor enable switch. Switching it to the down position will enable rain sensing. The Trellis will automatically close the Trellis from it detects the rain.
The two lower buttons are for Trellis panel control.
The left (yellow) momentary switch is for opening the Trellis roof panel. A single quick press and release will activate the Trellis to open the roof panel fully. If this button is pressed (and held), the panel will turn to open and halt only when the button is released.
The right (red) momentary switch is for closing the Trellis roof panel. A single quick press and release will activate the Trellis to close the roof panel fully. Similar to the open button, when this button is pressed (and held), the panel will do the closing and halt only when the button is released.
Trellis Multi-Bay Control Board
Multi-Bay Trellis control board from
Sunshade Trellis System Pte. Ltd. (Singapore)
This multi-bay board provides the control for 2 or more roof Trellis bay systems. It can be identified from the 4 switches user control wall switch.
This multi-bay user interface is similar to the single-bay version. It has an extra switch on the top left corner of the user switch panel. This button selects the bay that you want to control. Press one time for bay number 1, press two times for bay number 2.
The selected bay can be seen from the LED indicator (turned on) on the switch panel. The LED, starting from the left, indicates bay number 1, 2, 3, all the way to bay 6, which is the maximum number of Trillis roof bays this board can support.
Only when a bay is selected can the open/close button function. A blinking LED indicates that the board is now driving the motor of the particular bay when the open/close button is pressed. The LED indicator on the circuit board will also be lit up, indicating the status of the operation.

Battery Replacement
The system uses SLA (Sealed Lead Acid) battery as a means to drive the DC geared motor. Typical installation uses 12V 7Ah SLA battery. You can also use a smaller SLA battery rated 12V 1.3Ah.
These batteries can usually last for years, but they do wear off over time.
A typical full charge voltage measurement is expected to be between 13V to 13.8V. This is a healthly voltage level. When the voltage of the battery is measured below 12V, it is likely that the battery is worn and requires replacement.
Please handle the battery with care. Connect the correct polarity to the battery terminal. Please handle with care, and do not to short the positive (+) and the negative (-) terminal of the SLA battery, as it can catch fire instantly.
Motor Replacement
The motor used for this Trellis is a 12V geared DC motor (7 gear teeth version) that is typically used for the vehicle winding windows. It is important to note that there is a Left and Right versions of the motor.
The tools required to remove the motor panel is mainly a 10mm spanner and an Allen key set. The motor panel has to be dismounted in order for the motor to be replaced.
Trellis panel install calibration
These Trellis controllers are designed for simple installation without using any limit switch to set the motor motion boundary.
The Trellis calibrated position has its panel opened to 90 90-degree angle. At this angle, the gear teeth should be hitting the boundary limit stud. At the calibrated position, tighten the two M6 hex screw to lock the lever in position.
The panel’s closed position will naturally set the limit boundary. The panel will be closed tightly, resulting in a current surge which becomes an indicator for the controller to stop the motor.
