+
+Integrate [eWeLink](https://ewelink.cc/) smart switches (Sonoff, etc.) with [OctoPrint-PSUControl](https://github.com/kantlivelong/OctoPrint-PSUControl) to turn your 3D printer on and off remotely.
+
+## Features
+
+- **Cloud Integration**: Control any eWeLink-compatible device (Sonoff Basic, S26, etc.)
+- **Device Discovery**: Test connection and browse devices directly in OctoPrint settings
+- **State Sensing**: Real-time feedback on switch state
+- **Secure Credentials**: Passwords are encrypted locally using XOR obfuscation
+
+## Requirements
+
+- OctoPrint 1.3.10 or higher
+- [OctoPrint-PSUControl](https://github.com/kantlivelong/OctoPrint-PSUControl) plugin installed
+- eWeLink account and compatible smart switch
+- Active internet connection
+
+## External Services
+
+This plugin connects to the **eWeLink Cloud API** to control your smart devices. An active internet connection is required for all functionality. Your eWeLink credentials are transmitted securely over HTTPS to eWeLink's servers.
+
+The plugin does **not** collect or transmit any data to third parties other than eWeLink.
+
+## Setup
+
+1. Install via Plugin Manager
+2. Navigate to **Settings** → **PSU Control - eWeLink**
+3. Enter your eWeLink email and password
+4. Click **Test Connection / Get Devices**

+6. Save settings
+7. Go to **PSU Control** settings and select this plugin for switching/sensing
+
+## Troubleshooting

+- **Device Not Found**: Ensure the device is "Online" in the eWeLink app
+- **Connection Issues**: Check your internet connection; the eWeLink cloud must be reachable
