2. Setup and Initial Configuration
The Refoss Tasmota Smart Plug is designed for easy setup. Follow these steps to connect it to your Wi-Fi network and access its web interface.
2.1. Connecting to Wi-Fi:
- Plug In the Device: Insert the Refoss Tasmota Smart Plug into a power outlet.
- Search for AP Hotspot: On your smartphone or computer, search for Wi-Fi networks. You should find a network named "tasmota-XXXXXX-XXXX". Connect to this network.
- Access Web Interface: After connecting, your device should automatically redirect to the Tasmota configuration page (usually 192.168.4.1). If not, open a web browser and manually navigate to http://192.168.4.1.
- Enter Wi-Fi Information: On the Tasmota web interface, select your home Wi-Fi network from the list and enter its password. Click 'Save'.
- Obtain Device IP Address: The device will restart and connect to your home Wi-Fi. The web interface will then display the new IP address of the device on your network. Make a note of this IP address.
- Control and Configure: You can now access the device's web interface using its new IP address to control and configure it.

2.2. Firmware Update:
It is recommended to keep your Tasmota firmware updated for optimal performance and security. Ensure you select the correct firmware type (4M) to avoid device malfunction.
- Tasmota Official Firmware: You can find official Tasmota firmware versions at http://ota.tasmota.com/tasmota/release/. When updating, select the firmware file with "4M" in its name (e.g., `tasmota-4M.bin.gz`). Updating with a 2M firmware will cause the device to crash.
- Refoss Official Firmware: Refoss also provides validated firmware versions in multiple languages on their support page: https://support.refoss.net/Support/Resource_Library.
