The log-out still needs to also be transmitted to the WiFi data logger.
This happens automatically the next time the WiFi data logger
communicates with the Cloud. Depending on the communication cycle
selected, this may take some time. You can instruct the WiFi data
logger to establish a connection with the Cloud right away by briefly
pressing the button. This process is indicated by the green LED
flashing briefly. The WiFi data logger is logged out. After logging out of
the Cloud, press the buttons once briefly so that the WiFi data logger
receives the log-out.
