Why Does My JellyFish Lighting App Change All Calendar Event Off Times to 11 PM?
- Default off-time behavior / app bug
- Missing explicit off time (defaults to 11pm)
- Calendar event not saved correctly
Problem Description
You set a calendar event in the JellyFish Cloud app to turn lights off at, for example, 1 AM, and the moment you save it the off time silently rewrites itself to 11 PM. Every new calendar event behaves the same way. Reinstalling the app, power-cycling the controller, and deleting all calendar events do not fix it. Per JellyFish's official Schedules Troubleshooting article, this is almost always caused by the legacy JellyFish Designer app still running its own daily off-at-11pm schedule on the same controller and overriding the Cloud app.
Why This Happens in Real Homes
JellyFish calendar events reverting to an 11pm off time is a known quirk where events without an explicitly-set off time fall back to a default (11pm), or an app bug overwrites the set time. So an event you configured to turn off at, say, midnight shows up as turning off at 11pm instead.
The reliable workaround is to always set an explicit off time on each calendar event rather than leaving it to a default, and re-create any event that reverted with the correct times. Update the app, since JellyFish addresses these scheduling bugs in updates, and make sure events save and sync to the controller. Removing any conflicting default schedule and confirming the timezone helps too. Explicit off times keep events from defaulting to 11pm.
Symptoms
- Calendar event reverts to 11pm off
- Events change to 11pm
- Off time defaults to 11pm
- Calendar event time changed
- Event overwritten to 11pm off
- Schedule reverts to 11pm
- Unexpected 11pm off
- Calendar not keeping the set time
Recognize these? Here's what usually causes it.
Common Causes
- Default off-time behavior / app bug
- Missing explicit off time (defaults to 11pm)
- Calendar event not saved correctly
- App/cloud sync issue
- Conflicting default schedule
- App version bug
- Event overwritten by a default
- Timezone affecting the event
Most fixes happen in the first 3 steps.
Do not factory reset the controller as a workaround. Reset wipes your saved zones and color patterns, which JellyFish customer support can usually re-push remotely if you avoid the reset.
Tools & Requirements
Step-by-Step Solution
Confirm Designer App Is Still Installed Somewhere
Open every phone or tablet in the household used to control the JellyFish lights. Look for the older JellyFish Designer app icon (separate from the newer JellyFish Cloud app icon). Per JellyFish's official schedules troubleshooting article, if both the Designer and Cloud apps exist on the same controller account, one will silently override the other. The Designer app's factory-default Daily Off event sits at 11 PM, which exactly matches the symptom.
Delete All Schedules Inside the Designer App
Before uninstalling, open the JellyFish Designer app and tap into Schedules. Delete every Daily event and every Calendar event you see — including any greyed-out or holiday entries. Tap Save. JellyFish recommends this as the first remediation step so that no schedules are left orphaned on the controller after the Designer app is removed. Without this, the controller keeps the last-known Designer schedule even after the app is gone.
Uninstall the JellyFish Designer App
Once Designer-side schedules are wiped, uninstall the Designer app from every phone. On iPhone long-press the icon, tap Remove App, then Delete App. On Android long-press, drag to Uninstall, confirm. JellyFish's support docs explicitly recommend: delete the Designer app entirely and use only the Cloud app. Do this on every phone in the household — a single leftover Designer install will keep re-pushing the 11 PM schedule.
Reboot the Controller and Re-Test in Cloud App Only
Power-cycle the JellyFish controller for 60 seconds (unplug at the controller box, not just the breaker). Wait 2 to 3 minutes for it to fully boot and reconnect to JellyFish cloud servers. Open the Cloud app, create a fresh calendar event with your desired off time (e.g. 1 AM), tap Save, then re-open the same event to verify the off time is still what you entered. It should now hold.
Audit Daily vs Calendar Overlaps
Per JellyFish's overlap rule, calendar schedules CAN overlap daily schedules but two daily schedules cannot overlap each other. Open Cloud app Schedules and confirm there is exactly one Daily Off event (or none, if you only use calendar events). If you see two daily off events, delete one. If after all this it still snaps to 11 PM, contact JellyFish support at [email protected] — they can SSH into the controller and clear any orphaned schedule that the apps cannot see.
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.
Standardize on the Cloud app only across every household device. Every leftover Designer app install becomes a hidden writer of the controller's schedule and these conflicts are very hard to debug.
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.

- Missing explicit off time (defaults to 11pm)
- Calendar event not saved correctly
- App/cloud sync issue
- Conflicting default schedule
