990 Version Log
- another TCP enhancement (timeout & loop instead of blocking forever)
- issue with Viessdata csv if once_only poll items fixed
- vitolog.txt renamed to viconnlog.txt
29.11.2025
- switch to disable optolinkvs2_switch.log file
- some log messages removed, some log messages added
- logger_util some rework by ChatGPT
- cosmetics
Changes in settings_ini:
entries added:
no_logger_file = False # if true the optolinksvs2_switch.log will not get written
20.11.2025
- New TCP solution. Properly cleans up and releases all connections.
20.11.2025
- BB Filter one byte notation 'b:2' bug fixed
- new format specifiers added:
-
'boolinv'returns True if val == 0 else False -
'offon'returns ON if val == 0 else OFF
-
18.11.2025
- several times reworked regarding request_pointer and timing...
- return code on timeout with viconn_to_mqtt corrected
16.11.2025
- minor issue with request_pointer fixed
- request task control fixed: alternating Vitoconnect / (poll or mqtt or tcp) ensured
(previously 2 Viconn, 1 poll)
11.11.2025
- Vitoconnect traffic published on MQTT (may get disabled in ini)
- filter not to publish redundant data on MQTT (use command
reset_previousto re-initialize) - wo1c engery via RPC (as with vicare) implemented
- logger implemented -> optolinkvs2_switch.log
- timing changed to ensure possiblle reconnect after TCP exit
- some more minors?
- some Pylance stuff
Changes in settings_ini:
entries added:
viconn_to_mqtt = True # Vitoconnect traffic published on MQTT
mqtt_no_redundant = False # if True no previously published unchanged messages
# special for wo1c: read daily/weekly energy statistics +++++++++++
wo1c_energy = 0 # 0:disabled, €N: every n-th cycle
20.10.2025
- message when poll only once items removed from poll_list
- message telling with which poll item an error occured causing the script to exit
- moinors (mainly formal)
17.09.2025
- "poll only once" implemented: items in poll_list with poll_cycle set 0 get read only once and are removed from the poll_list after initial poll cycle.
- minors
12.09.2025
- implemented additional formats utf16 and vcaldatetime (first day of week = 00)
- some debug prints removed
- minors
12.09.2025
- affects one-wire utilization only
- sometimes you might realize runaways of 1w values. this release eliminates these by supressing values of high deviation against previous value up to 3 times.
- see c_w1value for details. if you need to change the checker parameters, edit line 30 of request_util.py
w1val = c_w1value.W1Value(addr, max_change=10.0, max_ignore=3)
17.06.2025
- made negative (integer) values possible with write command
18.04.2025
- print out MQTT messages other than cmnd
18.04.2025
- MQTT logging option implemented
Changes in settings_ini:
value added:
mqtt_logging = False # dis/enables logging of paho.mqtt (default: False)
18.04.2025
-
new format specifiers added:
-
'bool'returns True if val != 0 else False -
'onoff'returns ON if val != 0 else OFF -
'bin'returns data binary according to data/byte length -
'f:<frmt>'allows to specify any format accepted in a f" clause
-
-
format specifiers now can get used in combination with ByteBit Filter
30.03.2025
- ATTENTION: ByteBit Filter made congruent. Now returns raw/hex by default if no scale is given. So set scale to 1 to achieve the same result (decimal output) as in earlier versions without scale.
now("MyDatapoint", 0x1234, 3, 'b:2:2', 1),resturns same result as("MyDatapoint", 0x1234, 3, 'b:2:2'),before.
now("MyDatapoint", 0x1234, 3, 'b:2:2'),resturns same result as("MyDatapoint", 0x1234, 3, 'b:2:2::raw'),before.
Same withread; 0x1234; 3; b:2:2. Theraw'endian' is kept for downward compatibility but might get removed in future versions. If you use like("MySensorVal", 0x1234, 3, 'b:0:1', 0.1),nothing needs to be done.
Changes in settings_ini:
only default values changed:
port_vitoconnect = '/dev/ttyAMA0' # was ttyS0 before
resp_addr_format = 'x' # was 'd' before
16.03.2025
- If an issue occurs with Viconnect communication, the main loop gets stopped and everything starts again (protocoll init -> run Viconn reception thread -> main loop)
- serlog2log.py added to convert serlog to vitolog-like format
- retain of MQTT Topics selectable
initial Version is 1.3.0.0, there were some fixes/reworks in between
Changes in settings_ini:
value added:
mqtt_retain = False # Publish retained messages. Last message per topic is stored on broker and sent to new/reconnecting subscribers.
Feb 28, 2025
es gibt noch ein paar Änderungen, die bis hier nicht dokumentiert sind. Da wären z.B.
- Bug Fix bei Bit Mask Funktion im ByteBit-Filter
- LWT feature
- diverse 'kosmetische' Änderungen
- ...
für Details die Commits checken, vlt helfen die Kommentare ;-)
- poll_list now possible as poll_list.py file:
- if poll_list.py exists in working dir, poll list items are taken from there, else from settings_ini
- c_polllist introduced for that
- option PollCycle implemented for polling an item only every x-th time
- if first list item of poll item is int, it is taken as PollCycle
- olbreath time made configurable (olbreath in settings_ini)
- c_logging introduced for vitolog
Changes in settings_ini:
value added:
olbreath = 0.1 # Pause (seconds) after a request-response cycle (default: 0.1)
23.01.2025
- buffered csv writing implemented
- cmd 'FlushCsv' (TCP) for immediate writing
- buffer_to_write added to settings_ini
- receive_fullraw() enhanced (read_all, sleep 1ms->5ms)
Changes in settings_ini:
value added:
buffer_to_write = 60 # Buffer size before writing to CSV (default: 60)
11.05.2024
vitolog bug fix (module referece corrected)
06.05.2024
Support of reading 1-wire bus sensors implemented.
E.g. cheap an nearly zero-effort measuring/logging of additional temperatures possible.
Currently DS18B20 (Temperature) and DS2423 (4-Channel Counter) supported. Easy to expand.
Address not used by Optolink to be selected and entry in settings_ini.w1sensors dict to be added.
No scaling, byte len or signed used (everything done in read_w1sensor function)
