Hi! I see your iStrip+ app lights are stuck on red and you can’t change them. Let’s get that sorted out together.

First, just to narrow it down a bit—are all the lights stuck on red, or just a section of them? Also, do you control them solely through the iStrip+ app, or do you also have a remote or physical controller involved?

In the meantime, here’s a step-by-step approach we can try to fix the red-light issue:

1. Power Cycle the LED Strip
Unplug the LED strip from power completely. Leave it unplugged for about 30 seconds to a minute. Sometimes the controller needs a refresh. Then, plug it back in and see if the lights respond normally.

2. Check the Power Supply Voltage
LED strips that require 24V but are connected to a 12V power supply often show red colors by default. Verify the power supply matches the LED strip’s voltage requirements exactly.

3. Reset the Controller via the App
Within the iStrip+ app, look for a controller reset option (sometimes under settings or device info). Resetting the controller can clear any stuck color settings.

4. Re-pair the Device
Remove the LED strip device from the app and then add/pair it again. This can resolve communication glitches.

5. Check for Firmware or App Updates
Ensure your iStrip+ app and the device’s firmware are up to date. Updates sometimes fix color-related bugs.

6. Inspect Wiring and Connections
If possible, check the wiring and connectors for any loose or damaged cables. A poor connection sometimes causes the red color to stick.

Can you try these and tell me which steps you've already attempted? That way, I can suggest more advanced options if needed or help you through any specific step.

Let me know how it goes!
