These LEDs are normally invisible but will light up during startup, software updates, or if there’s a connectivity or system issue. Understanding each pattern helps you pinpoint the switch’s status and next steps. #### What Each LED Means The LEDs are labelled from left to right (1–6). | LED | When Solid (On) | When Flashing | | --- | --- | --- | | 1 (far left) | Boot first stage running | Boot failed | | 2 | Not connected to Wi-Fi | Attempting/failed Wi-Fi join | | 3 | Boot (2nd stage)/Not started | Not commissioned/not paired | | 4 | Booting | Not commissioned/not paired | | 5 | Booting | No internet connection | | 6 (far right) | Booting | Booting into recovery mode |   **Tip:** If all six LEDs are swirling from left to right, the switch is performing a firmware update. Allow it to complete before use.   #### Normal Boot Sequences #### For a Paired (Commissioned) Switch 1. Initial Boot: All six LEDs are on. 2. Second Phase: LEDs 2–6 remain on. 3. Wi-Fi Connected: LEDs 3–6 are on. 4. Boot Complete: All LEDs are off. #### For an Unpaired (Uncommissioned) Switch 1. Initial Boot: All six LEDs are on. 2. Second Phase: LEDs 2–6 remain on. 3. Ready for Commission: LED 2 is solid and LED 4 is flashing; others are off. #### Common Error Patterns & Solutions | LED Pattern | What It Means | Troubleshooting Steps | | --- | --- | --- | | 2 flashing, 3–6 solid | Wi-Fi missing/interference | 1. Ensure your router is on and broadcasting 2.4 GHz 2\. Restart router 3\. Relocate router/Use extender 4\. See \[Wi-Fi Troubleshooting Guide\] | | 3, 4, 6 solid, 5 flashing | No internet connection | 1. Test other device internet 2\. Contact ISP if needed 3\. Otherwise, follow \[Light Switch Troubleshooting Guide\] | | 1 flashing (far left) | Boot failed | 1. Switch off lighting breaker for 5 seconds, then on 2\. If repeated, contact Wondrwall Support | | All LEDs swirling \> 15 minutes | Stuck firmware upgrade | 1. Wait at least 15 minutes 2\. Soft reset (breaker cycle) 3\. Check internet connection |  **Recovery Mode (1, 3, and 6 flashing):** - Wait for automatic reboot. - If it persists, cycle the lighting circuit breaker for 5 seconds. - If still stuck, contact Wondrwall Support. #### Frequently Asked Questions **Can the switch still function with LEDs lit?** Yes. Brief LED patterns during startup or updates are normal. Only error patterns that persist longer than one minute require action. **What does a swirling LED pattern mean?** A firmware update is in progress. Wait up to 15 minutes. **Is manual control available if the switch is offline?** Yes, you can always use the touch surface to turn your lights on or off. **How do I know if the switch is offline?** - In the Wondrwall App, the switch icon appears grey with “Offline.” - On the device, LEDs 3, 4, and 6 will be solid and LED 5 flashes. **Can I disable the LEDs?** No, these diagnostic lights turn off automatically when not needed.   [![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Jul-31-2025-02-36-50-4197-PM.png?width=215&height=180&name=image-png-Jul-31-2025-02-36-50-4197-PM.png)](https://share.hsforms.com/1t4e_VqLLSZK4NZi2rRP4SQ1nzjg)   ### Help: Still need help after following these steps?
