Configuration
There are two ways to configure BSB-LAN:
- Through the configuration file
BSB_LAN_config.h
- Through the web-interface by calling http://bsb-lan.local/C (or the corresponding IP address)
For the initial configuration, some settings have to be configured in the configuration file (such as language and network settings).
Any further changes can be done also in the web-interface. It may, however, be useful to do the configuration (also) in the configuration file in case one needs to change the microcontroller. Almost all settings exist also in the web-interface and vice versa.
On an ESP32-based microcontroller, BSB-LAN will set up its own wireless access point named BSB-LAN
if it cannot connect to any network. So even without any further configuration, you can connect to this access point with the password BSB-LPB-PPS-LAN
and access BSB-LAN via the IP address http://192.168.4.1
and proceed with the configuration via this way. Keep in mind that if you have set a passkey or HTTP username and password, these are still required if these details are stored in EEPROM or BSB_LAN_config.h
.
Configuration through `BSB_LAN_config.h``
The configuration file consists of variables that are used in other parts of BSB-LAN. It is therefore important to only change the contents of the variables (i.e. the settings) and not the type of the variables. So if there is for example the setting
byte ip_addr[4] = {192,168,178,88};
you must not alter the byte ip_addr[4] =
part, only the contents, in this case the comma-separated IP address.
Configuration through the web-interface
Configuring BSB-LAN through the web-interface is pretty straightforward, as you don't have to deal with variable names but clear descriptions. Initially, only a selected number of configuration options are displayed in the webinterface. To have access to all of them, you have to set the "extended configuration" option to "on".

Adressing different heating controllers
In order to address parameters from devices other than the default destination device in the web-interface, you need to add an exclamation mark followed by the device address (see above for converting segment/device notation to device address).
For example, parameter 8700 from device address 1 would be written as 8700!1
instead of just 8700
.
For the configuration file, parameters are listed in the form {parameter number, destination address}
. Parameter 8700 from device address 1 would thus be written as {8700, 1}
. To address the default destination, you can do so by using -1
.
