If your Lightwave device is not linking to the app, follow the steps below to identify the cause and resolve the issue. --- ### 1. Put the device into pairing mode Depending on the device type, use the correct button combination: - **Dimmer**: Press and hold the **top and bottom buttons together** - **Relay or Socket**: Press and hold **one button** - **Boiler Switch**: Press and hold the **button on the left-hand side** --- ### 2. Check the LED flashing pattern Observe the LED indicator on the device: #### 🔵🔴 Flashing red and blue This means the device is in pairing mode. If it still does not link: - The **Link Plus may be out of range.** Please see more information [here](https://support.lightwaverf.com/knowledge/where-should-i-place-my-link-plus-hub?hsLang=en). - The device may **already be paired in the app**. Please make sure to delete the device before you re-pair it to the Link Plus Hub. See more information [here](https://support.lightwaverf.com/knowledge/how-to-delete-a-device-from-the-lightwaverf-app?hsLang=en)on deleting devices from the app. > Tip: Devices that are already paired are commonly found in the **top room of the Rooms list**. Be sure to scroll through and double-check all rooms. #### 🔴 Flashing red only This indicates the device memory is full. - A **master reset is required** before the device can be paired again. Please make sure to double- check that it isn't already in the app before master resetting. --- ### 3. Next steps - Move the **Link Plus higher** to the device and try pairing again - Confirm the device is **not already present** in the app - If required, perform a **master reset** and repeat the pairing process If the issue persists after following these steps, contact Lightwave Support for further assistance. ### 📞 Phone Support - **UK Support Line:** 0121 250 3625 - Available during standard business hours (Monday–Friday) ### 📧 Email Support - **Support Email:** [support-5@lightwaverf.com.hs-inbox.com](mailto:support-5@lightwaverf.com.hs-inbox.com) ### 🌐 Website - Visit the official website for support articles, product information, and live chat: - **https://lightwaverf.com** - [What do I need? & System Setup](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#main-content) - [Getting started on the Lightwave App](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#getting-started-on-the-lightwave-app) - [Lighting](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#lighting) - [Heating](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#heating) - [Automations](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#automations) - [Third Party Integrations](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#third-party-integrations) - [FAQ's](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#faqs) - [Advanced Features](https://support.lightwaverf.com/knowledge/what-do-i-need-system-setup?hsLang=en#advanced-features) - [App Guidance & Automations](https://support.lightwaverf.com/knowledge/app-guidance-automations?hsLang=en#main-content) - [My Account](https://support.lightwaverf.com/knowledge/app-guidance-automations?hsLang=en#my-account) - [App Guidance](https://support.lightwaverf.com/knowledge/app-guidance-automations?hsLang=en#app-guidance) - [Automations](https://support.lightwaverf.com/knowledge/app-guidance-automations?hsLang=en#automations) - [Troubleshooting](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#main-content) - [General](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#general) - [Lighting](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#lighting) - [Heating](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#heating) - [Power](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#power) - [Automations & Hub](https://support.lightwaverf.com/knowledge/troubleshooting?hsLang=en#automations-hub) - [Installation Guides](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#main-content) - [Link Plus Hub](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#link-plus-hub) - [Lighting](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#lighting) - [Power](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#power) - [Relays](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#relays) - [Heating](https://support.lightwaverf.com/knowledge/installation-guides?hsLang=en#heating) - [Connect Series Support Archive](https://support.lightwaverf.com/knowledge/connect-series-support-archive?hsLang=en#main-content) - [General](https://support.lightwaverf.com/knowledge/connect-series-support-archive?hsLang=en#general) - [Lighting](https://support.lightwaverf.com/knowledge/connect-series-support-archive?hsLang=en#lighting) - [Heating](https://support.lightwaverf.com/knowledge/connect-series-support-archive?hsLang=en#heating) - [Power](https://support.lightwaverf.com/knowledge/connect-series-support-archive?hsLang=en#power) - [Contact Us](https://support.lightwaverf.com/knowledge/contact-us?hsLang=en#main-content) - [Product Returns](https://support.lightwaverf.com/knowledge/contact-us?hsLang=en#product-returns) - [Contact Us](https://support.lightwaverf.com/knowledge/contact-us?hsLang=en#contact-us) [![Chill listening crop-3](https://support.lightwaverf.com/hs-fs/hubfs/Lightwave%20Logo%20Green%20Small%20(320%20x%20132)-1.png?width=58&height=24&name=Lightwave%20Logo%20Green%20Small%20(320%20x%20132)-1.png "Chill listening crop-3")](http://lightwaverf.com) [mailto:email@email.com](mailto:email@email.com) Copyright © 2025, Lightwave
