v1.1

ATTENTION: The next release will contain several fundamental changes which will break some of the configurations, so that an update WILL require you to adjust your settings! If the current Master branch version is not working for you, try this one here. Also, Mega2560 users should still be able to run this version if not all modules are activated:

• 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
• Many new parameters decoded
• New parameters for device families 25, 44, 51, 59, 68, 85, 88, 90, 96, 97, 108, 134, 162, 163, 170, 195, 209, 211
• Improved mobile display of webinterface
• Added definement "BtSerial" for diverting serial output to Serial2 where a Bluetooth adapter can be connected (5V->5V, GND->GND, RX->TX2, TX->RX2). Adapter has to be in slave mode and configured to 115200 bps, 8N1.
• Lots of added Polish translations
• New data types VT_BYTE10, VT_SPF
• Bugfix for PPS bus regarding display of heating time programs
• Bugfix for MQTT

v1.0

ATTENTION: Next release will include new categories (and therefore a shift in category numbers) and also move the DHW Push parameter from 1601 to 1603. If you are installing BSB-LAN for the first time, please get the most recent code from the master repository to avoid making these changes with your next update.

• /JI URL command outputs configuration in JSON structure
• /JC URL command gets list of possible values from user-defined list of functions. Example: /JC=505,700,701,702,711,1600,1602
• Logging telegrams (log parameter 30000) now writes to separate file (journal.txt). It can be reset with /D0 (same time with datalog.txt) command and dumped with /DJ command.
• removed WIFI configuration as it is no longer applicable for the Due
• lots of new parameters for various device families
• Code optimization and restructuring, general increase of speed
• new schemativs for board layout V3
• lots of bugfixes

v0.44 - Last version completely tested on Mega 2560!

• Added webserver functionality via SD card and various other improvements from GitHub user dukess
• more parameters and device families
• Added JSON output for MQTT
• mobile friendlier web interface
• last version completely tested on Mega 2560. Future versions may still run on the Mega, but will only be tested on the Arduino Due.

v0.43

• Added support for HardwareSerial (Serial1) connection of the adapter. Use RX pin 19 in bus() definition to activate. See manual/forum for hardware details.
• Added definement DebugTelnet to divert serial output to telnet client (port 23, no password) in BSB_lan_config.h
• Added possibility to control BSB-LAN (almost?) completely via USB-serial port. Most commands supported like their URL-counterparts, i.e. //xxx to query parameter xxx or //N to restart Arduino.
• Changed default device ID from 6 (room controller "RGT1") to unused ID 66 ("LAN")
• Many new parameters, please run /Q to see any possible changes for your device family and report back to us!
• Added global variables (arrays of 20 bytes) custom_floats[] and custom_longs[] for use with BSB_lan_custom.h, for example to read sensors etc. Output of these variables is done via new URL command /U
• Added device families 23 and 29 (Grünenwald heaters)
• Added device families 49, 52, 59 (Weishaupt heaters)
• Added device fmilies 91, 92, 94, 118, 133, 136, 137, 165, 184, 188 (various controllers like QAA75 or AVS37)
• Added device family 171 (Bösch wood pellet system)

• New data types VT_CUSTOM_ENUM and VT_CUSTOM_BYTE to extract information from non-standard telegrams (such as 702/703)
• Bugfix: DHCP (ethernet) implementation

v0.42

• 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
  For example: #define LANG DE
  This parameter is now mandatory!
• 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 JSON export; query with /JQ=a,b,c,d... or push queries to /JQ or push set commands to /JS

• Added Waterstage WP device family (119)
• Added WHG Procon device family (195)
• Added unit to log file as well as average output
• Rewrote device matching in cmd_tbl to accomodate also device variant (Gerätevariante). Run /Q to see if transition has worked for your device!
• 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
• Split of cmdtbl into cmdtbl1 and cmdtbl2 due to Arduino's(?) limit of 32kB size of struct, opening up more space for new parameters.

v0.41

This is an interim release with the state prior to moving all texts from the source code to separate language files in folder "localization".

v0.40

• Implemented polling of MAX! heating thermostats, display with URL command /X.
  See BSB_lan_custom.h for an example to transmit average room temperature to heating system.

  Use setBusType(2) to set to PPS upon boot or /P2 to switch temporarily.
• Set GPIOs to input by using /Gxx,I
• Definement "#define CUSTOM_COMMANDS" added.
  Use this in your configuration to include individual code from "BSB_lan_custom.h"
  (needs to be created by you!) which is executed at the end of each main loop.
  Variables "custom_timer" and "custom_timer_compare" have been added to execute
  code at arbitrary intervals.
• several new parameters added

• Bugfixing SD-card logging in monitor mode

• Bugfix for setting hour:time parameters via webinterface

v0.37

• LPB implementation
  More than 450 parameters supported! Switch temporarily between LPB and BSB with the Px command (0=BSB, 1=LPB) or use the setBusType config option to set bus-type at boot-time. Parameter numbers are the same as for BSB.
• change of config variable "device_id"
  Now called "fixed_device_id". When updating to this version, please change your BSB_lan_config.h file accordingly if you do not use the one provided in this release.
