How Do I Fix Zones That Won't Respond in the JellyFish Lighting App?
- Zone is assigned to a controller port that is currently offline or has a wiring fault
- Zone was incorrectly mapped in the Designer App during setup — the port assignment does not match the physical wiring
- A conflicting schedule is overriding zone commands immediately after they are sent
Problem Description
One or more zones in the JellyFish Cloud App do not respond to commands — tapping a color, pattern, or on/off control for the zone has no visible effect on the lights, even though other zones on the same controller work normally.
Symptoms
- Tapping a color or pattern for a specific zone produces no change in the lights
- The zone appears in the app but is unresponsive to all commands
- Other zones on the same controller respond normally
- Zone was recently renamed or reconfigured and now does not work
- Zone responded previously but stopped working after a firmware update
Recognize these? Here's what usually causes it.
Common Causes
- Zone is assigned to a controller port that is currently offline or has a wiring fault
- Zone was incorrectly mapped in the Designer App during setup — the port assignment does not match the physical wiring
- A conflicting schedule is overriding zone commands immediately after they are sent
- The zone was added to the Cloud App account but the controller configuration was not saved after zone setup
- Controller needs a restart to apply a recently changed zone configuration
Most fixes happen in the first 3 steps.
Deleting a zone also removes all schedules associated with that zone from the controller. Before deleting a zone to recreate it, take note of all schedule times and patterns assigned to it so you can rebuild them after the zone is recreated.
Tools & Requirements
Step-by-Step Solution
Zone Names Must Be Unique
If two zones have the same name, the app may send commands to the wrong zone. Rename zones with distinct, descriptive names (e.g., Front Roofline, Left Side, Backyard) to prevent confusion and potential command routing errors.
Maximum Zones Per Controller
The JellyFish Pro 2 controller supports up to 4 output ports. Each port can be a separate zone. If you have more than 4 zones, your installation uses multiple controllers. Ensure the correct controller is selected in the app when managing zones.
Zone Changes Require Controller Save
Any change to zone setup in the Designer App must be saved to the controller memory before exiting. If the Designer App was closed without saving, the zone change was not applied and the zone configuration will revert to its previous state on the next restart.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If flickering only happens on dimming, the issue is almost always the dimmer's minimum-load setting, not the bulb — it's drawing less current than the dimmer expects.
To identify which controller port corresponds to which section of lights, use the front panel to activate each port individually at full brightness and walk outside to see which lights respond. This port-mapping exercise takes 10 minutes and prevents zone assignment errors.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
