What is the T-Splitter?

The T‑Splitter allows one signal line to drive two separate light branches.
  • It can be connected directly to the controller output to split the signal from Out1 or Out2.
  • Or it can be inserted midway in a light string to branch off and create two independent sections.

When to Use?

 
  • When you want to run two light strings in opposite directions from the same controller
  • Ideal for “center-out” layouts on eaves, fences, or rooftops

How to Set Up

  • Connect the T-splitter at the desired branch point.
  • Set the correct number of lights for Out1 and Out2 on the controller. Make sure the lights remain ON.
  • Open the ASAHOM App and tap the “+” icon in the upper right corner to add a T-splitter.
  • After detection, select the brand and model according to your actual product (e.g., ASAHOM S1070).
  • Set the number of LEDs on each branch based on your layout.
  • Wait for about 1 minute, then the lights can be controlled normally.

How Are the Lights Ordered?

After the T‑Splitter is configured, the system treats Branch Out and Main Out as two consecutive sections:
  • The light sequence starts from Branch Out and continues into Main Out.
  • For effects that flow across all lights (like gradients or chases), the system sees Branch Out → Main Out as a single continuous string.

Important Notes

  • This component splits signal only, not power.
  • Neither the main output nor any branch output of the T-splitter may exceed 288 LEDs.
  • If the indicator light is distracting, you can disable it via the app.

Multi-Splitter Connection

We do not limit the number of splitters that can be used in your setup.
However, when configuring the number of lights for each splitter branch, make sure to include all light strings connected along that branch.
For example, if a branch has two additional splitters connected in series, you need to add up the total number of lights across that entire branch. This ensures accurate signal mapping and synchronized lighting effects throughout the system.

FAQs

Q1: What's the difference between T-Splitter and Power Injection T-connector?
A1: T-Splitter splits signal only.Power Injection T-connect adds extra power for long runs.
 
Q2: Can I exceed 288 LEDs per branch?
A2: No. Each branch (Out1/Out2) must stay within 288 LEDs.
 
Q3: Do I need to use T-Splitter for every setup?
A3: No. Only use it when your layout requires two branches from one controller output.
 
Q4: What if lights don’t respond after setup?
A4: Check Out1/Out2 light count settings in the app and ensure the T-Splitter is paired.

Q5: Is the splitter compatible with WLED mode?
A5: Yes, the splitter works normally in WLED mode.
