The light on your OcuTrap tells you what the trap is doing. This guide explains what each color and pattern means — including why the light looks off most of the time when the trap runs on battery (that's normal and expected).


"The light is off when the trap is idle" — is that a problem?

No — that's normal battery‑saving behavior. When the trap is idle and running on battery, it keeps the light off between brief check‑in flashes. Roughly every 10 seconds you'll see one quick flash (a fraction of a second), then it goes dark again. The trap is fully awake and working — it just isn't lighting the LED continuously, because a steady light would drain the battery.

  • On external/USB power (or for a few seconds right after you send a command), the light stays on — a slow breathing cyan glow when the trap is connected.
  • On battery, expect the brief flash every ~10 seconds. To confirm the trap is alive, send any command from the app — the light will brighten immediately.

Only be concerned if, when the trap should be sitting idle, the light stays solid on one color that never changes, or stays red. See Red light below.


Color meanings

The flash (or steady color) shows the trap's current state:

ColorMeaning
BlueUnarmed, door open
GreenUnarmed, door closed
YellowArmed — ready to capture
Magenta / pinkAnimal captured

Fast blinking cyanConnecting to the cloudWait a few minutes
Blinking greenLooking for cellular signalMove the trap to better coverage
Blinking magentaFirmware update in progressLeave it powered on and wait

When you send a command

The light briefly confirms your action, then returns to its idle pattern:

You doLight
Open the doorBlue for ~5 seconds
Close the doorGreen for ~5 seconds
Arm the trapYellow while it checks the capture zone (~3 seconds), then yellow once armed
Arm is blocked — something is in the way, the sensor needs cleaning, or an update is pendingSolid red for ~2 seconds, then back to idle. The trap did not arm. Clear the obstruction or clean the sensor window and try again.

Red light

PatternMeaning
Brief solid red (~2 seconds) after a commandThe action was blocked (for example, arming failed) — see the row above
Rapid red blinkingPowering down, or a low‑battery shutdown
Solid red (staying red)Hibernating or shut down
