Chapter 4 System Configuration
System Data
The WISE data logger function not only logs the I/O status, but also logs system
events for module diagnostics or troubleshooting. You can decide what kind of sys-
tem events you would like to log here.
– Logger Configuration
In the previous page, you configured which data is logged. In this page you can
enable the local memory storage function. There are separate switches for enabling
logging I/O data or system data. You can turn ON the switches to enable logging.
– Local Data Query
The logged data can be queried from the WISE module. Due to the limitation of MCU-
based WISE modules, the file will be saved in a *.json file. You can visit https://json-
csv.com/ to convert the data from *.json to *.csv.
Before querying the logged data, you can configure the format of the file. You can
decide whether the data comes with a UUID or MAC ID, and decide the type of time
stamp. For the latest version WISE module version, which supports Local Date and
Time (GMT) the time stamp will look like: "2015-08-27T15:20:29+08:00", or if it sup-
ports Coordinated Universal Time (UTC) that the time stamp will looks like:
“1440660089”.
After deciding the data format you can query the data by the Amount of Latest Data
for a quantity of data, or by Time Filter for a period of data. However, if the amount of
data is not too large, you can also choose No Filter Enabled to query all the data.
Now you can click Query to query the data from local memory. Then the data will be
shown in a chart and table. Click Save to download the data from the WISE module
in a *.json file. Or you can click Clear to clear all the data in local memory.
