# Wirelessly linking a Lightwave relay and dimmer using a Group Automation
## This article explains how to set up a Lightwave relay and dimmer to communicate wirelessly using a Group Automation in the Lightwave app, including important wiring warnings and step-by-step setup instructions.
---
### ✅ Before You Start
Before creating the automation:
- Both the relay and dimmer must already be paired to the Lightwave app
- Both devices should appear online in the app
- The Link Plus Hub should show a solid green LED
---
### 🔗 How to Create a Group Automation
Follow these steps to make the relay and dimmer communicate wirelessly:
1. Open the **Lightwave App**
2. Tap the green **+** button at the bottom centre of the screen
3. Select **Automations**
4. Tap **Group**
5. Select **Switch**
6. Select both:
- The Relay
- The Dimmer
7. Tap **Next**
8. Enter a name for the automation
9. Tap **Done** in the top-right corner
---
### ✅ What Happens After Setup?
Once the Group automation is created:
- The dimmer and relay will mirror each other
- Turning one device on or off will control the other
- Communication happens wirelessly through the Link Plus Hub
This is ideal for setups where devices cannot be physically wired together.
---
### 💡 Additional Notes
- Group automations require the Link Plus Hub to remain powered
- Internet is only needed to create the automation
- Once created, automations continue to operate locally through the hub
---
### 📞 Need Further Help?
If the relay and dimmer are not responding correctly after setup:
- Check both devices are online in the app
- Confirm the Link Plus LED is solid green
- Restart the Link Plus Hub if needed
