Once added in ON/OFF mode: - The relay becomes discoverable and controllable by AHK, Google, and Alexa. - You can still utilise the O/S/C commands internally through automations. --- ### 🔄 Create Two IF-DO Automations in the Lightwave App Even though you’ve added the relay as ON/OFF, you can map ON to OPEN and OFF to CLOSE using Lightwave’s **IF-DO automation.** #### 🔧 **Automation 1 – ON = OPEN** 1. Open the Lightwave app and go to **Automations**. 2. Tap **Add Automation** and select **IF-DO**. 3. Under **IF (Trigger)**: - Select the relay - Choose **Switch** - Set to **ON** 4. Under **DO (Action)**: - Select the same relay - Choose **O/S/C** - Set to **OPEN** 5. Name and save the automation. 🎉 Now, turning the relay ON from any app or voice command will trigger the **OPEN** action. --- #### 🔧 **Automation 2 – OFF = CLOSE** 1. Go to **Automations** and tap **Add Automation**. 2. Under **IF (Trigger)**: - Select the relay - Choose **Switch** - Set to **OFF** 3. Under **DO (Action)**: - Select the relay - Choose **O/S/C** - Set to **CLOSE** 4. Name and save the automation. 🎉 Turning the relay OFF will now trigger the **CLOSE** action. --- ### 🗣️ Improve Voice Control Experience By default, voice platforms will use “turn on/off” commands for your relay (e.g., “Turn on blinds”), which may feel unnatural. You can customise this using scenes and routines: #### ✅ **In Alexa:** - Create a **routine** with your preferred voice phrase. - Example: Saying **“Alexa, open blinds”** triggers the relay ON. #### ✅ **In Apple HomeKit:** - Add a **custom scene**: - Name: *Open Blinds* - Accessory: Select your relay - Set state to **ON** - Now you can say **“Hey Siri, open blinds”**. Repeat the process for **CLOSE** using relay OFF. --- ### ⏱️ Optional: Add a STOP Command (Motor Safety) For certain electric motor setups, it may be necessary to stop movement after OPEN or CLOSE. This requires a second action: #### Example: **Trigger:** Relay ON **Action 1:** O/S/C → OPEN **Action 2:** O/S/C → STOP (with a 5-second delay) This ensures the motor doesn’t continue running unnecessarily.   - [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) - [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
