Operating Instructions
1. All-in-One Control Center
The NSPanel acts as a central control hub for your smart home. It allows for one-tap activation of specific scene modes and is compatible with most SONOFF devices, enabling centralized control of device groups.

2. Smart Temperature Control
Utilize the built-in thermostat to set desired indoor temperatures for different time periods. The NSPanel will automatically activate heating or cooling equipment to maintain a comfortable room temperature based on your settings.

3. Time, Weather, and Temperature Display
With integrated sensors and Wi-Fi connectivity, the NSPanel provides real-time updates for weather conditions, indoor temperature, outdoor temperature, current time, and date.

4. Multiple Control Methods
Control your NSPanel and connected devices using various methods:
- Dual-Channel Switches: Physical buttons on the panel for direct control.
- Touchscreen: Interactive display for managing devices and settings.
- eWeLink App: Remote control via your smartphone.
- Voice Control: Compatible with Amazon Alexa, Google Home, and Siri Shortcuts.

5. Smart Scene Setup
Create custom smart scenes to automate your home based on conditions and actions. For example, if the kitchen light is on, then turn on the coffee machine plug. Or, if the living room light is off, then turn on the bedroom light.
