Why Are My JellyFish Lighting Zones Out of Sync With Each Other?
- Zones were not started simultaneously — a command lag caused different zones to begin their animation at different times
- The controller lost its sync state during a power interruption and zones restarted their animation cycles at different offsets
- Different zone lengths cause the same animation to appear at different points in each zone's cycle
Problem Description
When running a synchronized multi-zone pattern or effect, different zones display the same pattern at different offsets in time — appearing to chase each other or run the same animation out of phase, rather than displaying a unified synchronized effect.
Symptoms
- A chasing or scrolling pattern looks different on each zone — one side is ahead of the other
- Zones that should show the same color simultaneously display slightly different phases of the same animation
- After turning all zones on at the same time, they are visibly misaligned within seconds
- A synchronized holiday pattern looks correct on Zone 1 but runs behind on Zones 2 and 3
- Synchronization issue appeared after a power outage or controller restart
Recognize these? Here's what usually causes it.
Common Causes
- Zones were not started simultaneously — a command lag caused different zones to begin their animation at different times
- The controller lost its sync state during a power interruption and zones restarted their animation cycles at different offsets
- Different zone lengths cause the same animation to appear at different points in each zone's cycle
- Multi-zone sync requires a specific app setting that was not configured, causing zones to run independently rather than as a synchronized group
Most fixes happen in the first 3 steps.
Sending rapid successive commands to multiple zones can cause a race condition where different zones receive their commands milliseconds apart, causing synchronization drift. Always use the All Zones control for synchronized effects rather than individually selecting each zone.
Tools & Requirements
Step-by-Step Solution
Static Colors Are Always in Sync
Synchronization issues only affect animated patterns (chasing, fading, scrolling). Static solid colors are always perfectly synchronized across all zones regardless of how they were started, because there is no animation timing component.
JellyFish Pattern Sync Is Controller-Level
The Pro 2 controller coordinates all zone outputs from a single clock source. True sync issues at the hardware level are very rare — most perceived sync issues are caused by delayed start times or different zone lengths creating visual phase differences.
Contact Dealer for Custom Pattern Sync
If you need precisely synchronized multi-zone animated displays for specific events (holiday shows, architectural displays), your authorized dealer can create and upload a custom synchronized pattern file to the controller that locks all zones to the same animation frame.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If pairing fails after multiple attempts, the device may still be registered to a previous account — factory-reset it before trying to add it to a new one.
For the most visually cohesive whole-home display, use the All Zones control in the Cloud App to apply patterns. This ensures every zone starts the same animation simultaneously without any timing offset.
Pairing failures almost always come down to distance during the initial handshake — manufacturers seriously understate how close you actually need to be.
- Zones were not started simultaneously — a command lag
- The controller lost its sync state during a power
- Different zone lengths cause the same animation to appear
- Multi-zone sync requires a specific app setting
