I wanted to learn COBOL so I wrote a program in it that fetch temperature and humidity data from my Tellstick DUO and inserts it into a database.

This COBOL source was tested with Open COBOL on ubuntu.

Run compile_mock.sh to compile a file with a mocked Tellstick interface, and some random data.

Run compile.sh to compile and link against tellstick library. In this case, this program requires that telldus-core is installed and working: http://developer.telldus.se/

Both scripts needs MySQL headers and libraries.

Run the compiled binary. All known sensors will be polled and the temperature and humidity will be stored to the database.

Needed environment variables: MYSQL_USER, MYSQL_PASSWD, MYSQL_HOST, MYSQL_DATABASE and MYSQL_TABLE

The following table structure is expected:

+-------------+-------------+
| Field       | Type        |
+-------------+-------------+
| sensorId    | varchar(10) |
| temperature | double      |
| humidity    | int(11)     |
| timestamp   | int(11)     |
+-------------+-------------+

Because it amused me.
