# Replacing a Qilowatt Device with the Same Model

## Introduction

 This guide applies to all Qilowatt devices.
Replacement can only be done with the **same device model** – for example, a **Modbus R2** can only be replaced by another **Modbus R2**.
In that case, all previously configured settings on your account will remain unchanged.

⚠️ Replacement is only possible if the offline device **has not been deleted** from your account.

## Step-by-step Guide

### **1. Resetting and connecting the device to Wi-Fi**

  **1.** **Do not delete** the offline device from your account before resetting and reconnecting it.
**2.** Perform a **factory reset** by holding the reset button for at least **45 seconds**.
**3.** Perform a **restart** – disconnect the power for about **5 seconds**, then turn the device back on.
**4.** Using your phone or computer, check whether a **Wi-Fi network** named **Qilowatt-XXXXXX** is visible.
**5.** Connect to the Qilowatt Wi-Fi network.
• If a **popup window**appears, confirm the connection.
• If the setup window **does not appear automatically**, open a browser and go to **192.168.4.1**, then press Enter.  ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/3446f885-557a-44b6-a28d-80d7384b351f-235x300.png) **6.** Select your home Wi-Fi network and enter:
• Your Qilowatt App email address
• Your **Wi-Fi password**, then click **Save**.

If the information is correct, the device will connect automatically and confirm the connection.

Wait 3–4 minutes, then check whether the device appears on your Qilowatt account.

### **2. Replacing the device in the Qilowatt App**

 If the setup window returns to the first screen, verify:
• The**Qilowatt App email**is entered correctly.
• The **Wi-Fi password**is correct.

Ensure capital and lowercase letters are entered accurately in both email and password.

### **3. Connection check and troubleshooting**

 **1.** Log in to your Qilowatt App account.
**2.** On the dashboard, you should see **three devices.** ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/17d24da3-6420-4d20-ab4a-6bda06768e96.png) **3.** Click on the **offline**device in your account: ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/2abe43a1-f5fc-413b-b50c-4258174d424e.png) **4.** Click on **Edit** in the device information: ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/6a0ed7ab-0c6f-4aba-a452-c22f0ef06811.png) **5.** Click **Replace device**: ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/0d476265-7776-4b4d-848c-780d6c3b95c4.png) **6**. From the dropdown, select the new device of the same type.
**7.** Click **Start replacement process**.

No confirmation message will appear – the replacement process runs automatically.

### **4. Final check**

 • Wait 5–6 minutes for the replacement to complete.
• Once successful, the previous offline device will be deleted automatically.
• Verify that all previous**settings are preserved** and the new device is visible on your dashboard. ![](https://docs.qilowatt.eu/wp-content/uploads/2025/10/675b6113-64b8-4a02-ba30-4551218a3922.png)
