The logging API will send an HTTP request to the CMS API on a 10 min interval basis. An HTTP response is sent back, containing the disconnection event if any. Later, those events are recorded in the database.|@|~(^,^)~|@|The web application user interface, which shows the environmental values measured at the installed station.|@|~(^,^)~|@|Map showing the locations of 167 LED smart lighting devices.|@|~(^,^)~|@|User interface of historical gateway connection devices. The table shows the disconnection log for each gateway device along with other useful information such as device name and current connection status. The yellow highlighted rows show the most recent disconnection event.|@|~(^,^)~|@|Correlation matrix for assessing correlation between different parameters, i.e., illuminance, ultraviolet A, temperature, ultraviolet B, wind velocity, air pressure, and relative humidity, respectively.|@|~(^,^)~|@|Scatter plot of predicted against actual values, and a linear fitting illustrating the correlation between illuminance and Ultra Violet A.|@|~(^,^)~|@|Illuminance profile with some missing values introducing gaps in the time-series data.|@|~(^,^)~|@|Presence of missing values.
