CCU.IO adapter for monitoring heat pump with Luxtronik2 (Novelan, Wolf, Alpha Innotec)

!!! Never trust a software developer !!! Always be sure what you are doing!

This software is developed and tested on a Siemens/Novelan SIC-8HE heatpump. It should work with all Alpha-Innotec luxtronik 2.0 based controller. Information about luxtronik where mainly extracted from https://opendta.sourceforge.net/ Additional information was extracted from various forum threads.

CCU.IO settings

MySQL table will be created automatically if it is defined in settings and does not exist

{
  "enabled": true,
  "mode": "periodical",
  "period": 60,
  "firstId": 101000,
  "settings":
  {
    "host": "192.168.2.100",   => ip address of heatpump
    "port": 8888,              => should be always 8888
    "mysql":                   => remove for no mysql database
    {
      "host": "127.0.0.1",     => ip of mysql server
      "user": "USER",          => mysql server user name
      "pass": "PASS",          => mysql server password
      "database": "DATABASE"   => logging database name (table name is luxtronik)
    }
  }
}

main module

• general initialisation
• read out luxtronik spot values
• store calculated values in rega and database

helper functions

Init data types, rega and mysql database

This files contains a description of all luxtronik 2.0 channels based on firmware 1.69

channel names and type based on https://opendta.sourceforge.net/ additional channel names where extracted from wp.jar archive of luxtronik

each channel is described by name, type(, enum) like

INDEX : { "name": FRIENDLY_NAME, "type": TYPE, "dp": DATAPOINT[, "enum": ENUM_VALUES] }

INDEX - numeric index in luxtronik response

FRIENDLY_NAME - shows meaning of channel; used as MYSQL column name

TYPE - how to translate the value

"ignore" - do not use this value

"fix1" - has one decimal place (must divide by 10)

"ip" - IPv4 address

"unixtime" - unix timestamp (seconds since 01.01.1970) as ISO string

"timestamp" - leave as int32 but creates TIMESTAMP column in mysql

"enum" - use ENUM_VALUES to translate (value is index)

undefined - use value unchanged (as int32)

DATPOINT - sort channels to groups

• "TEMPERATURE" - all temperatures (usually float (fix1) with unit "°C")
• "OUTPUT" - output state (usually boolean value, stored as int32)
• "INPUT" - input state (usually boolean value, stored as int32)
• "ANALOG" - measure values (usually float (fix1) with unit "mV")
• "COUNTER" - incremental values (usually a timespan with unit "s")
• "TIME" - timestamps (usually reported as unix timestamp)
• "WMZ" - calculated values based on sensor (usually with unit "kWh")
• "ERROR" - everything belonging to error tracking,
• "MISC" - everything else which is unknown or not sorted in other categories

"TEMPERATURE", "OUTPUT", "INPUT", "ANALOG", "COUNTER", "TIME", "WMZ", "ERROR", "MISC" - see above
"valtype" - HM valtype (2=boolean; 4=float; 16=int; 20=string)
"unit" - default channel unit (can be overwritten for each channel)
