Hi, ADD_Li.
How to log in to SmartLogger2000 after the IP address is forgotten: Long press the Default button for more than 10s to bind the default IP address (192.168.0.10). When the button is pressed for more than 10s, the RUN indicator flashes green quickly (0.125s on and 0.125s off), and other indicators are off; at this time, release the button and log in with the factory default IP address for 5 minutes Effective within.
Thanks!
