ChangeLog

Current Master

  • ATTENTION: BREAKING CHANGE! Streamlined topic structure for MQTT. New strucuture adds /status for querying a parameter, /set for SETting a parameter, /inf for sending data as INF telegram and /poll to force BSB-LAN to send an update of that parameter value to the broker. If you are using MQTT auto-discovery, ideally, calling /M1 should update these changes. However, if you are using your own configurations, you'll have to make adjustments here.
  • ATTENTION: BREAKING CHANGE! When using JSON settings for MQTT, previously all messages were written to the BSB-LAN/json and thus basically immediately overwritten when logging several parameters. Now this setting only determines the format (and not format and topic) of the data that is written into /status of each parameter. For auto-discovery, plain text remains the only valid choice.
  • ATTENTION: BREAKING CHANGE The acknowledgement message sent by BSB-LAN to the MQTT topic has been removed. Instead, QoS for publishing messages has been set to level 1.
  • Added setting to only publish log parameters to MQTT. Forcing MQTT updates via /poll topic are still possible.
  • Added state_class for non cumulative sensors in MQTT auto-discovery
  • Updated the room unit emulation in custom_functions to work with version 4.x.
  • Bugfix for VT_ENERGY, added new data type VT_ENERGY10 and VT_ENERGY10_N

Version 4.1

06.11.2024

  • ATTENTION: BREAKING CHANGE! Changed topic structure for MQTT. This means that all existing MQTT entities in your home-automation system will have to be adjusted or created anew! The new structure now is BSB-LAN/<device id>/<category id>/<parameter number>.
  • ATTENTION: BREAKING CHANGE! Changed unique_id for MQTT auto-discovery. This means that all MQTT entities that have been created via auto-discovery will have to be created anew!
  • ATTENTION: Configuration options fixed_device_family and fixed_device_variant have been removed since they no longer work for device-specific parameter lists. If your heating system is off when turning on the microcontroller, BSB-LAN will try to acquire the details every 60 seconds.
  • ATTENTION: Change of configuration options results in new EEPROM layout, therefore EEPROM will be reinitialized based on configuration of BSB_LAN_config.h.
  • MQTT auto-discovery now works for all devices, not only device ID 0. Use /M1!<x> or /M0!<x> to create/remove entities for device ID <x>.
  • Changed MQTT auto-discovery messages' flag to "retain" so that parameters remain available after reboot of Home Assistant.

Version 4.0

01.11.2024

  • ATTENTION: BREAKING CHANGE! Room temperature parameter 10000, 10001 and 10002 must now have the additional flag FL_SPECIAL_INF, otherwise setting temperature will not work!
  • ATTENTION: BREAKING CHANGE! Outside temperature simulation parameter 10017 must have FL_SPECIAL_INF flag removed, otherwise setting temperature will not work!
  • ATTENTION: BREAKING CHANGE! Room temperature parameter 10000, 10001 and 10002 for Weishaupt heaters (device families 49, 50, 51 and 59) must now have FL_SPECIAL_INF flag removd, otherwise setting temperature will not work!
  • ATTENTION: BREAKING CHANGE! URL commands /U (dislpay user-defined variables) and /X (display MAX! values) have been removed as these values can now be accessed via parameters 20000++
  • ATTENTION: BREAKING CHANGE! PPS time program parameters (15050-15091) have been streamlined with BSB/LPB time program parameters, resulting in only one parameter per day (instead of six), covering three switch points (start and end) per parameter.
  • ATTENTION: For ESP32, BSB-LAN requires ESP32 framework version 3.0.x - please look out for errors or strange behaviour (1-Wire sensors are still not tested) as well as any other kind of strange behaviour/crashes.
  • ATTENTION: New configuration options in BSB_LAN_config.h - please update your existing configuration files! Web-based configuration will be overwritten with config file settings due to change in EEPROM layout!
  • ATTENTION: New manual URL: https://docs.bsb-lan.de/
  • BUTTONS and RGT_EMULATION have been moved from main code to custom_functions library. To continue using them, make use of BSB_LAN_custom_*.h files and activate CUSTOM_COMMANDS definement.
  • Most configuration definements removed from BSB_LAN_config.h. Almost all functionality can now be configured without reflashing.
  • BSB-LAN now supports MQTT auto discovery (supported e.g. by Home Assistant). To create devices, call URL command /M1, to remove them call /M0
  • ATTENTION: MQTT auto discovery creates a general switch for the BSB-LAN device in Home Assistant. This switch will immediately write all parameters with the values stored in Home Assistant. DO NOT USE THIS SWITCH unless you REALLY know what it does!
  • "Set" button in webinterface now also works with non-default destination devices (i.e. 1 instead of 0)
  • Queried/set parameters are now forwarded to the MQTT broker (if MQTT is enabled)
  • Previously used /M1 and /M0 for toggling monitor function have been removed since it can now be accessed via the configuration in the webinterface.
  • Listing categories with /K now also works with destination device (e.g. /K!1 for destination device 1, default is 0).
  • Important bugfix for OTA update: Previous versions had a hard limit on file size which newer heating systems with several hundred parameters hit, so no OTA update was possible. This is now fixed, but affected users will have to make a USB-based update one more time.
  • 1-Wire- and DHT-sensors are now be disabled with value -1 instead of 0. In web interface, an empty field is also accepted.
  • MQTTTopicPrefix is no longer optional, "fromBroker" topic removed (formerly used to send commands to BSB-LAN via MQTT)
  • Using the 24h averages functionality no longer requires the use of an SD card. SD card will only be used to store averages if interval logging to SD card is active.
  • New PPS room unit variant for RVD130, which increases high nibble of magic byte at every transaction.
  • Polling current time from NTP server is active by default. Deactivate by setting ntp_server to empty string.
  • New parameter flag FL_NOSWAP_QUR for parameters that do not swap the first two bytes of command ID in QUR telegram
  • New parameter flag FL_FORCE_INF for parameters from which we are certain they only work with INF (such as room temperature). Will force an INF telegram even if /S is used to set the parameter (allows setting room temperature via web interface)
  • BSB-LAN logo watermark in log graph display (DE-cr)
  • Binary ENUMs (yes/no, on/off etc.) now return either 0 or 1 when queried, not - as is the case with some heating systems - 0 or 255. Setting any value from 1 to 255 is still possible.
  • Fixed a breaking bug in PPS that prevented running properly in active/room unit mode.
  • Fixed bug (or, based on perspective, reduced security) that prevented issuing commands via serial/telnet console when HTTP authentication was active
  • Various bugfixes, among others logging of bus telegrams on storage device.
  • New OneWireNg library version
  • This release has been supported by the following sponsors: Erich Scheilko

Version 3.3

12.03.2024

  • ATTENTION: New configuration options in BSB_LAN_config.h - please update your existing configuration files!
  • ESP32: Support for receiving date and time via NTP instead of taking it from the heater.
  • MQTT broker setting now accepts domain names as well as IP addresses. An optional port can be added after a trailing colon, e.g. broker.my-domain.com:1884. Otherwise defaults to 1883.
  • ESP32 NodeMCU: Support for optional additional SD card adapter. SPI pins can be configured in BSB_LAN_config.h, defaulting to standard SPI pins 5, 18, 19 and 23.
  • ESP32: Switching between log storage device (SD card / internal flash) can now be done in the web interface.
  • ESP32: Create temporary WiFi AP in case Ethernet connection fails
  • ESP32 NodeMCU: EEPROM clear pin has changed from 18 to 21 in order not to collide with SPI SD card adapters.
  • This release has been supported by the following GitHub sponsors: jsimon3

Version 3.2

15.11.2023

  • ATTENTION: In BSB_LAN_config.h, new layout of log_parameters, avg_parameters and ipwe_parameters now written in curly brackets and different size (40 instead of 80) and type (parameter instead of float). Please update your BSB_LAN_config.h accordingly to prevent errors!
  • Added configuration file versioning checks to prevent the use of outdated configuration files with newer software versions.
  • Variable esp32_save_energy now defaults to false because it only seems to make sense when using LAN connection or if you use WiFi and can live with the performance impact.
  • Added folder custom_functions where code examples for useful functions will be collected which are nevertheless too specific to be added to BSB-LAN's core code.
  • Added custom function example for mapping DS18B20 sensors to fixed custom floats parameters
  • This release has been supported by the following GitHub Sponsors: BraweProg, fdobrovolny, Harald

Version 3.1

04.06.2023

  • ATTENTION: For ESP32 devices using internal flash for log storage: Filesystem was switched from SPIFFS to LittleFS. Download important log data before updating!
  • ATTENTION: In BSB_LAN_config.h, the structure of log_parameters, avg_parameters and ipwe_parameters has changed and now includes the destination device on the bus!
  • ATTENTION: New EEPROM schema may result in lost web-configuration settings when updating. Note your settings prior to updating!
  • ATTENTION: New variable esp32_save_energy in BSB_LAN_config.h - update before compiling new version.

  • Parameters can now be queried from other devices on the bus using the ! notation also when logging (including MQTT) or using average or IPWE parameters
  • Enable/disable power saving on ESP32. Saves 20% of energy, but can have impact on WiFi range and downloading speed of log files when using WiFi (LAN not affected)
  • Improved performance and flash memory usage on ESP32 devices using internal flash for logging due to switch from SPIFFS to LittleFS
  • To improve handling of large datalogs: date range selection in /DG, new url commands /Da,b, /DA, /DB, /Dn, /DI and /DKn
  • This release has been supported by the following GitHub Sponsors: lapixo, nrobadey

Version 3.0

16.03.2023

  • Device-specific parameter lists supported

Version 2.1

30.07.2022

  • Many new parameters for LMU64

  • ATTENTION: LOTS of new functionalities, some of which break compatibility with previous versions, so be careful and read all the docs if you make the upgrade!
  • ATTENTION: Added and reorganized PPS parameters, almost all parameter numbers have changed!
  • ATTENTION: Change of EEPROM layout will lead to loading of default values from BSB_LAN_config.h! You need to write settings to EEPROM in configuration menu again!
  • ATTENTION: Folder locations and filenames have been adjusted for easier installation! If you update your installation, please take note that the configuration is now in BSB_LAN_config.h (LAN in caps), and no longer in BSB_lan_config.h (lower-caps "lan")
  • ATTENTION: HTTP-Authentication configuration has changed and now uses plain text instead of Base64 encoded strings!
  • Thanks to GitHub user do13, this code now also compiles on a ESP32, tested on NodeMCU-ESP32, Olimex ESP32-POE and Olimex ESP32-EVB boards. ESP32 code uses SDK version 2.0.2, please take note when configuring Arduino IDE!
  • OTA Updates now possible for ESP32-based devices
  • Support for special PPS devices (based on DC225/Honeywell MCBA) added
  • Webinterface allows for configuration of most settings without the need to re-flash, also split into basic and extended configuration
  • Added better WiFi option for Arduinos through Jiri Bilek's WiFiSpi library, using an ESP8266-based microcontroller like Wemos D1 mini or LoLin NodeMCU. Older WiFi-via-Serial approach no longer supported.
  • Added MDNS_SUPPORT definement in config so that BSB-LAN can be discovered through mDNS
  • If BSB-LAN cannot connect to WiFi on ESP32, it will set up its own access point BSB-LAN with password BSB-LPB-PPS-LAN for 30 minutes. After that, it will reboot and try to connect again.
  • New MQTT functions, including allowing any parameter to be set by an MQTT message and actively query any parameter once by sending an MQTT message
  • Added support for BME280 sensors
  • Setting a temporary destination address for querying parameters by adding !x (where x is the destination id), e.g. /6224!10 to query the identification of the display unit

  • URL command /JB allows for backing up parameters to JSON file
  • New library for DHT22 should provide more reliable results
  • Consolidated data and value types: New data types VT_YEAR, VT_DAYMONTH, VT_TIME as subsets of VT_DATETIME for parameters 1-3, replacing VT_SUMMERPERIOD and adjusting VT_VACATIONPROG. New value types DT_THMS for time consisting of hour:minutes:seconds
  • MQTT: Use MQTTDeviceID as a client ID for the broker, still defaults to BSB-LAN. ATTENTION: Check your config if you're broker relies on the client ID in any way for authorization etc.

Version 1.1

10.11.2020

  • ATTENTION: DHW Push ("Trinkwasser Push") parameter had to be moved from 1601 to 1603 because 1601 has a different "official" meaning on some heaters. Please check and change your configuration if necessary
  • ATTENTION: New categories added, most category numbers (using /K) will be shifted up by a few numbers.
  • /JA URL command outputs average values

Version 0.42

21.03.2019

  • Added localization! Now you can help translate BSB-LAN into your language! Simply copy one of the language files from the localization folder (LANG_DE.h is the most complete) and translate whatever you can. Non-translated items will be displayed in German. Attention: Language definition in BSB_LAN_config.h is now #define LANG <ISO-CODE> For example: #define LANG DE
  • Added export to MQTT broker, use log_parameters[] in BSB_LAN_config.h to define parameters and activate MQTTBrokerIP definement.
  • Added support for WiFi modules such as an ESP8266 or a Wemos Mega connected to Serial3 (RX:15/TX:14) of the Arduino. The ESP8266 has to be flashed with the AT firmware from Espressif to work. Please take note that WiFi over serial is by design much slower (only 115kpbs) than "pure" TCP/IP connections.
  • Added new category "34 - Konfiguration / Erweiterungsmodule". All subsequent categories move one number up!
  • Lots of new parameters coming from device family 123, please run /Q to see if some parameters also work for your heater!
  • Lots of new yet unknown parameters through brute force querying :) (parameter numbers 10200 and above)
  • Added further PPS-Bus commands, moved parameter numbers to 15000 and above
  • Default PPS mode now "listening". Use third parameter of bus definition to switch between listening and controlling, 1 stands for controlling, everything else for listening, i.e. BSB bus(68,67,1) sends data to the heater, BSB bus(68,67) only receives data from heater / room controller. You can switch between modes at run-time with URL command /P2,x where x is either 1 (for controlling) or not 1 (for listening only)
  • Fixed bug that crashed PPS bus queries
  • Stability improvements for PPS bus
  • Improved graph legend when plotting several parameters

  • Added BSB_LAN_custom_setup.h and BSB_LAN_custom_global.h for you to add individual code (best used in conjunction with BSB_LAN_custom.h)
  • Marked all (known) OEM parameters with flag FL_OEM. OEM parameters are set by default as read-only. To make them writeable, change FL_OEM from 5 to 4 in BSB_LAN_defs.h
  • Increased performance for querying several parameters at once (similar to category query)
  • Added config option to define subnet.
  • /Q no longer needs #define DEBUG
  • Bugfix ENUM memory adressing
  • Bugfix in reset function /N, clear EEPROM during reset with /NE
  • Added favicon.ico

Version 0.32

18.04.2017

  • lots of new parameters suppoerted
  • newly designed webinterface allows control over heating system without any additional software or cryptic URL commands. URL commands of course are still available, so no need to change anything when using FHEM etc.
  • German webinterface available with definement LANG_DE
  • new URL-command /LB=x to log only broadcast messages (x=1) or all bus messages (x=0)
  • new URL-command /X to reset the Arduino (need to enable RESET definement in BSB_LAN_config.h)
  • new logging parameters 20002 and 20003 for hot water loading times and cycles
  • moved DS18B20 logging parameters from 20010-20019 to 20200-20299 and DHT22 logging parameters from 20020-20029 to 20100 to 20199
  • moved average logging parameter from 20002 to 20004
  • set numerous parameters to read-only because that's what they obviously are (K33-36)
  • various bugfixes

Version 0.31

10.04.2017

  • increased dumping of logfile by factor 5 / as long as we still have memory left, you can increase logbuflen from 100 to 1000 to increase transfer speed from approx. 16 to 18 kB/s
  • adjusted burner activity monitoring based on broadcast messages for Brötje systems
  • removed definement PROGNR_5895 because so far, it has only disabled an ENUM definition.
  • removed definement PROGNR_6030 because double command ID could be resolved via BROETJE / non-BROETJE definements
  • renamed BROETJE_SOB to BROETJE in order to allow for fine-grained distinction between different BROETJE cases (e.g. 6800ff) This means you have to activate TWO definements when using a Brötje system now: The general BROETJE as well as BROETJE_SOB or BROETJE_BSW. Have a look at your serial log for parameters 6800 to see which command IDs fit your system and activate one of both accordingly.
  • changed 16-Bit addressing of flash memory to 32-Bit to address crashes due to ever growing PROGMEM tables - now we have lots of air to breathe again for new command IDs :)
  • removed trailing \0 string from several ENUMs that led to wrong ENUM listings. Please keep in mind not to end ENUMs with a trailing \0 !

Version 0.30

22.03.2017

  • Time library by Paul Stoffregen (https://github.com/PaulStoffregen/Time) is now required and included in the library folder.
  • adds logging of raw telegram data to SD card with logging parameter 30000. Logging telegram data is affected by commands /V and /LU
  • adds command /LU=x to log only known (x=0) or unknown (x=1) command IDs when logging telegram data
  • removed define USE_BROADCAST, broadcast data is now always processed
  • new internal functions GetDateTime, TranslateAddr, TranslateType

Version 0.29

07.03.2017

  • adds command /C to display current configuration
  • adds command /L to configure logging interval and parameters
  • adds option for command /A to set 24h average parameters during runtime

  • bugfixes for logging DS18B20 sensors

Version 0.28

05.03.2017

  • adds special parameters 20000++ for SD card logging of /B, /T and /H commands (see BSB_LAN_config.h for examples)

Version 0.27

01.03.2017

  • adds date field to log file (requires exact time to be sent by heating system)
  • /D0 recreates datalog.txt file with table header
  • added "flags" field to command table structure. Currently, only FL_RONLY is supported to make a parameter read-only
  • added DEFAULT_FLAG in config. Defaults to NULL, i.e. all fields are read/writeable. Setting it to FL_RONLY makes all parameters read-only, e.g. for added level of security. Individual parameters can be set to NULL/FL_RONLY to make only these parameters writable/read-only.
