If your Horizon Pergola LED lights work from the remote but not from the mobile app, this usually means the lighting hardware is functioning properly and the issue is related to app sync, cloud communication, device permissions, or controller settings.
Because the remote works, this is typically not a power or LED failure.
Common Symptoms
Problem | Example |
Remote Works | Lights turn on/off using remote |
App Does Nothing | No response from Tuya app |
Roof Works in App | Louvers respond, lights do not |
Delayed Response | Lights react after several seconds |
Step 1: Confirm Device Is Online in App
Check | Details |
Tuya Device Status | Must show Online |
Wi-Fi Connected | Stable internet required |
Roof Control Works | Test louvers in app |
If the pergola shows offline, resolve connectivity first.
Step 2: Refresh the App
Action | Details |
Pull to Refresh | Update device status |
Close/Reopen App | Restart Tuya app |
Sign Out / In | Refresh account session |
Temporary sync issues can prevent lighting commands.
Step 3: Check Light Controls Inside App
Some versions place lights under a separate control panel.
Look For |
Light icon |
ON/OFF toggle |
Brightness slider |
Warm / Cool mode |
Scene settings |
If roof controls work, explore the device page fully.
Step 4: Test Basic Commands First
Test | Expected Result |
Lights ON | Lights activate |
Lights OFF | Lights turn off |
Brightness 50% | Dimmed output |
Color Mode Change | Warm/Cool switch |
Use simple commands before advanced automations.
Step 5: Power Cycle the Pergola
Step | Action |
1 | Turn pergola power OFF |
2 | Wait 30 seconds |
3 | Turn power back ON |
4 | Reopen app and test |
This can restore controller/app communication.
Step 6: Remove and Re-Add Device
If lights still fail only in app:
Action |
Delete pergola from Tuya app |
Put controller into pairing mode |
Add device again |
Retest lights |
Re-pairing often refreshes missing functions.
If Remote Works But App Lights Do Not
Possible causes:
App sync issue
Device partially connected
Outdated Tuya app version
Cloud delay
Lighting channel not loaded correctly
Controller firmware issue
