You cannot log in without being assigned a valid TSI role.
The LED at the bottom of the BlueSky monitor will flash once every two seconds when connected to Wi-Fi. If it flashes twice or three times repeatedly, the BlueSky monitor is not connected to the WiFi and there is a connectivity problem. However, it will continue to function normally, and, if an SD card is installed, data will be stored onto the SD card.
Data will also be logged in the firmware for a limited time (data is logged for approximately one week at 15 minute intervals) and once the Wi-Fi connection is re-established, the buffered data is posted to TSI Link Solutions. However, if there is no WiFi or internet connection for over a week, TSI Link Solutions will start missing data.
