The dynamic response time of Anker SOLIX Smart Plug is slightly more than 3 seconds. 

Since the Anker app interface refreshes values every 3 seconds, when Smart Plug is connected to a load, the power station interface will show energy drawn from the grid after 3 seconds. However, the power station interface will show power supplied from the Solarbank 2 E1600 Pro/Plus only after 6 seconds.
