How Do I Set Up Sunrise/Sunset Automation in the JellyFish Lighting App?
- User created fixed clock-time schedules instead of sunset/sunrise triggers
- Location data was not granted to the JellyFish Cloud App, preventing sun position calculation
- Offset minutes for the sunset trigger were not configured, causing lights to activate exactly at sunset rather than slightly before
Problem Description
The JellyFish Cloud App supports automatic sunrise and sunset-based schedule triggers that adjust daily based on your location. Setting these up correctly ensures lights always activate at dusk and deactivate at dawn without needing manual seasonal adjustments.
Symptoms
- Lights turn on at the wrong time relative to sunset because fixed-time schedules do not adjust seasonally
- User wants lights to activate automatically at dusk every day without updating schedules twice a year
- Lights are turning off too early in winter or too late in summer
- User is unsure how to configure sunset triggers in the Cloud App interface
Recognize these? Here's what usually causes it.
Common Causes
- User created fixed clock-time schedules instead of sunset/sunrise triggers
- Location data was not granted to the JellyFish Cloud App, preventing sun position calculation
- Offset minutes for the sunset trigger were not configured, causing lights to activate exactly at sunset rather than slightly before
- Controller timezone is set incorrectly, throwing off the sunset calculation
Most fixes happen in the first 3 steps.
Sunrise and sunset times are calculated based on your location and date. Ensure your JellyFish account timezone and location are accurate — an incorrect timezone of even one hour will cause the lights to activate noticeably off from actual dusk.
Tools & Requirements
Step-by-Step Solution
Sunset Offset Recommendation
For residential exterior lighting, a good starting point is: turn On 10 minutes before sunset, turn Off 30 minutes after sunrise. This ensures lights are active during the full darkness window while not wasting energy during daylight hours.
Seasonal Benefits
In summer, sunset may be as late as 8:30pm in northern US locations. In winter, it may be as early as 4:30pm. Sunset-triggered schedules handle this 4-hour seasonal range automatically — fixed-time schedules cannot.
Test with a Forced Trigger
After creating sunrise/sunset schedules, you can test them immediately by temporarily adding a fixed-time schedule 5 minutes in the future to verify the On/Off actions work correctly before relying on the sunset trigger.
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.
For a complete hands-free system, set the On trigger to Sunset minus 10 minutes and the Off trigger to Sunrise plus 30 minutes. These offsets ensure lights are active through the entire darkness window without burning energy during daylight.
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.
