Why Are My JellyFish Lighting Schedules Not Working?
- Controller offline at the scheduled time
- Wrong timezone set
- Cloud/AWS dependency (offline schedule)
Problem Description
Your JellyFish Lighting scheduled lighting events are not firing — lights do not turn on, change patterns, or turn off at the configured times. JellyFish schedules are managed differently between the Designer App and Cloud App, and running both simultaneously is the most common cause of schedule conflicts.
Why This Happens in Real Homes
JellyFish scheduled events not running usually trace to the controller's connection or its clock — schedules rely on the controller being online at the scheduled time and on the correct timezone, and because scheduling runs through the JellyFish cloud, a controller that's offline (or a cloud hiccup) at the trigger moment misses events. Conflicting events and DST shifts are the next suspects.
Keep the controller reliably online (fix any 2.4GHz drops), confirm the timezone is set correctly in the app, and remove overlapping schedules that fight each other. Set your home location if you use sunrise/sunset events, and re-check timing after daylight-saving changes. Make sure each schedule is enabled and saved, and re-sync the app with the controller. An online controller with the right time and non-conflicting events runs schedules reliably.
Symptoms
- Schedules not working
- Scheduled events don't run
- Lights don't turn on/off on schedule
- Schedule ignored
- Only some events fire
- Schedule stopped
- Timing off
- No scheduled changes
Recognize these? Here's what usually causes it.
Common Causes
- Controller offline at the scheduled time
- Wrong timezone set
- Cloud/AWS dependency (offline schedule)
- Conflicting/overlapping events
- Daylight-saving shift
- Schedule not enabled/saved
- App-to-controller sync issue
- Location not set (for sun times)
Most fixes happen in the first 3 steps.
Clearing all schedules from the Designer App will remove them permanently from that app. However, schedules saved in the Cloud App are unaffected and will continue to work normally.
Tools & Requirements
Step-by-Step Solution
Manage Schedules Only in the Cloud App
JellyFish officially recommends managing all schedules exclusively in the Cloud App. The Designer App is intended for initial installation and pattern design only. If you have schedules set in both apps, they can conflict and override each other unpredictably. Delete the Designer App from your phone after setup is complete and manage all ongoing schedules in the Cloud App only.
Switch to Sunrise and Sunset-Based Triggers
The Cloud App supports astronomical sunrise and sunset triggers that automatically adjust with the seasons. These are significantly more reliable than fixed-time schedules for exterior lighting. Replace fixed-time ON and OFF rules with a Sunset trigger for the on time and a Sunrise or fixed late-night time for off. This eliminates drift as days lengthen or shorten throughout the year.
Verify Controller Internet Connectivity
JellyFish schedules are cloud-executed, meaning the controller must have active internet access to receive and trigger scheduled events. Open the Cloud App and check the controller status. If it shows offline, schedules will not fire until connectivity is restored. Restart the controller by powering it off for 30 seconds and confirm it reconnects to the app before relying on scheduled triggers.
Test a Schedule 5 Minutes in the Future
After making any schedule changes, create a test schedule set to fire 5 minutes from the current time and watch the lights. This confirms the scheduling system is working before you rely on overnight or next-day schedules. If the test schedule fires correctly but your regular schedule does not, the issue is in the rule configuration — check AM versus PM, the correct days of the week, and that no override is active.
Delete and Recreate Problem Schedules
If a specific schedule consistently fails to trigger, delete it entirely from the Cloud App and recreate it from scratch. Do not edit an existing failing rule — delete it and build a new one. Corrupted or partially saved schedule entries can appear correct in the interface but fail silently. After recreating, run the 5-minute test to verify the new rule fires before saving it for daily use.
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.
After resolving schedule conflicts, test by temporarily setting a schedule 5 minutes in the future and confirming it fires correctly. This confirms the scheduling system works before you rely on an overnight Off schedule.
Thermostat issues that keep returning are often caused by stale backup-battery memory holding old settings across power cycles without the user realising.

- Wrong timezone set
- Cloud/AWS dependency (offline schedule)
- Conflicting/overlapping events
- Daylight-saving shift
