Why Do My JellyFish Lights Stay On After the Schedule Says Off?
- Controller offline at the off time
- Overlapping/conflicting schedule keeping them on
- No off event / off time missing
Problem Description
JellyFish lights remain illuminated past their configured Off schedule time, burning through the night or past sunrise, indicating a schedule configuration error, a schedule conflict, or a manual override that was not cleared.
Why This Happens in Real Homes
JellyFish lights staying on past their scheduled off time usually means the off event didn't fire — most often because the controller was offline at that moment (scheduling runs through the cloud), an overlapping schedule is keeping them on, or a manual override is active. A missing or mis-timed off event is the other common cause.
Keep the controller reliably online through the off time, and check your schedule for conflicts: an overlapping event or a sun-based trigger can keep the lights on past a fixed off time. Make sure the off event actually exists with the correct time, clear any manual override, and verify the timezone/DST hasn't shifted the off time. Re-sync the app and controller. An online controller with a clean, non-conflicting off event turns the lights off on time.
Symptoms
- Lights stay on past the off time
- Won't turn off on schedule
- Still lit after the off event
- Off schedule ignored
- Lights don't shut off
- Remain on after the scheduled off
- Off event not firing
- Lights on all night
Recognize these? Here's what usually causes it.
Common Causes
- Controller offline at the off time
- Overlapping/conflicting schedule keeping them on
- No off event / off time missing
- Manual override active
- Cloud dependency at the off moment
- Sun-based event conflict
- App-to-controller sync issue
- Timezone/DST shifting the off time
Most fixes happen in the first 3 steps.
Manually turning lights off via the Cloud App does not clear or cancel future schedule events. If a schedule is set to turn lights on again later, they will turn on as scheduled. Manual overrides are temporary until the next scheduled event.
Tools & Requirements
Step-by-Step Solution
Test Off Schedule Within 10 Minutes
After saving a new Off schedule, test it by temporarily setting the Off time to 5 minutes from now. Watch whether the lights turn off at that time. If they do, the schedule system is working. Delete the test schedule and recreate the Off schedule at the correct time.
Off vs. Black Pattern
There are two ways to effectively turn lights off: use an Off schedule (cuts power output to that zone) or use a Black pattern schedule (displays black, which produces no light but keeps the zone powered). For nighttime off states, use a true Off schedule to fully cut the zone output and reduce power consumption.
Sunrise Trigger Is the Most Reliable Off Method
The most reliable way to make sure lights turn off when it gets light is to use a Sunrise trigger for the Off event. This automatically adjusts to the actual sunrise time at your location each day.
Quick Solutions
Still having issues? This is usually the deeper cause below.
Schedules that skip randomly are usually a daylight-saving holdover — delete and recreate the schedule to clear the corrupted entry.
Testing a new Off schedule by setting it 5 minutes in the future is the fastest way to verify the scheduling system works before relying on an overnight Off event.
Thermostat issues that keep returning are often caused by stale backup-battery memory holding old settings across power cycles without the user realising.
- Controller offline at the off time
- Overlapping/conflicting schedule keeping them on
- No off event / off time missing
- Manual override active
- Cloud dependency at the off moment
