Using BSB-LAN
Controlling the heating system via the web-interface
As a first step – or if you just want to turn your heating system on or off – you can simply open the BSB-LAN web-interface and go to the Settings menu. This will display a list of categories from your heating controller.
You can click on each category and will get a list of corresponding parameters. If you see a Set button, it means the parameter can be changed, and clicking on the button will send the new value to the heater. If there is no Set button, the parameter is read-only and there is no way to change the parameter.
Using BSB-LAN's URL commands
Most of BSB-LAN's functionality can be controlled using URL commands. These are useful or even necessary when connecting BSB-LAN to a home automation system, but also provide access to functions not directly accessible via the web-interface.
URL commands are called right after BSB-LAN's hostname and an (optional) passkey. So to get a list of categories, one would have to open the URL http://bsb-lan.local/K (or http://bsb-lan.local/1234/K if the passkey 1234 is in use).

Using the graphical plot functionality
If logged data on storage (either SD card or internal flash) is available, the Display log file becomes clickable. By default, it will display the logged data in the browser.
To access the logged data itself (in the file datalog.txt), use the /D URL command mentioned above.
By default, "Display log file" displays the log data of the most recent n calendar days (n=DEFAULT_DAYS_TO_PLOT, configurable in BSB_LAN_config.h). Subsequently, controls on the web page can be used to select a different range, depending on the data contained in the log file
Mouseover, click and mouse wheel actions within the graphical display provide various control options:
- Better legibility for value numbers with plot lines close to each other (mouseover on plot)
- Users can interactively highlight plot lines for improved overview (mouseover on legend entries)
- Users can interactively disable plot lines for improved overview and vertical scaling (click on legend entries)
- Zoom (mousewheel/pinch on plot) and pan capability (drag zoomed-in plot)
