[Codebeispiel] Openhab und Domiq LCN

[koboldo]

Moin,
hier wollte ich mal kurz für alle interessierten die Anbindung von Openhab an Domiq präsentieren.
Ich habe hierzu das TCP-Binding benutzt:

openhab.cfg

################################# TCP - UDP Binding ###################################
#
# all parameters can be applied to both the TCP and UDP binding unless
# specified otherwise
 
# Port to listen for incoming connections
tcp:port=3000
 
# Cron-like string to reconnect remote ends, e.g for unstable connection or remote ends
tcp:reconnectron=0 0 0 * *
 
# Interval between reconnection attempts when recovering from a communication error,
# in seconds
tcp:retryinterval=5
 
# Queue data whilst recovering from a connection problem (TCP only)
tcp:queue=true
 
# Maximum buffer size whilst reading incoming data
tcp:buffersize=1024
 
# Share connections within the Item binding configurations
#tcp:itemsharedconnections=true
 
# Share connections between Item binding configurations
#tcp:bindingsharedconnections=true
 
# Share connections between inbound and outbound connections
#tcp:directionssharedconnections=true
 
# Allow masks in ip:port addressing, e.g. 192.168.0.1:* etc
tcp:addressmask=true
 
# Pre-amble that will be put in front of data being sent
#tcp:preamble=''
 
# Post-amble that will be appended to data being sent
#tcp:postamble=''
 
# Perform all write/read (send/receive) operations in a blocking mode, e.g. the binding
# will wait for a reply from the remote end after data has been sent
tcp:blocking=true
 
# timeout, in milliseconds, to wait for a reply when initiating a blocking write/read
# operation
tcp:timeout=3000
 
# Update the status of Items using the response received from the remote end (if the
# remote end sends replies to commands)
tcp:updatewithresponse=true
 
# Timeout - or 'refresh interval', in milliseconds, of the worker thread
tcp:refreshinterval=250
 
# Timeout, in milliseconds, to wait when "Selecting" IO channels ready for communication
#tcp:selecttimeout=1000
 
# Used character set
#tcp:charset=ASCII

Hier mal einige Items Einträge als Beispiel

domiq.items

String domiq { tcp=">[[b][i]IP-DOMIQ[/i][/b]:4224:'REGEX((.*))']" }
Contact s_sofafenster "Wozi Fenster [%S]" <contact> (g_fenster,g_mysql)
Dimmer l_wozi "Wozi" <light> (g_mysql,g_l_dg)
Rollershutter r_wozi "Wozi [%S]" <rollershutter> (g_rolladen,g_rolladeneg,g_mysql)
Number lux "Helligkeit [%.1f Lux]" <sun> (gwettertemp,gwetter,g_mysql)
Number t_wozi "Wohnzimmer [%.1f °C]" <temperature> (g_mysql,g_wozi,gwettertemp,gtemp,g_t_wozi)
String t_wozi_min "- Min. Temp [%s]" <temperature>
String t_wozi_max "- Max. Temp [%s]" <temperature>

Dann benötigt man noch Rules zum einen um die Daten von der Domiq zu verarbeiten:

domiq.rules

import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*
import java.lang.*
 
rule "domiqs"
when
Item domiq received update
then
var txt = domiq.state.toString
var Integer anzahl = txt.split("\\s+").size
var String[] txtleer
txtleer = txt.split("\\s+")
var String[] txt_ergeb
 
for (i: 0 .. (anzahl - 1))
{
txt_ergeb = txtleer.get(i).split("=")
if (txt_ergeb.get(1) != ("?")) {
if (txt_ergeb.get(0) == ("LCN.value.0.9.r2")) t_wozi.postUpdate((new Double(txt_ergeb.get(1)) - 1000)/10) else
if (txt_ergeb.get(0) == ("VAR.KOBELKA.event.lux")) lux.postUpdate(txt_ergeb.get(1)) else
if (txtleer.get(i) == ("LCN.sensor.0.21.3=1")) s_sofafenster.postUpdate(CLOSED) else
if (txtleer.get(i) == ("LCN.sensor.0.21.3=0")) s_sofafenster.postUpdate(OPEN) else
if (txt_ergeb.get(0) == ("VAR.roll_position_rel.21.2")) r_sofafenster.postUpdate(txt_ergeb.get(1)) else
if (txt_ergeb.get(0) == ("LCN.output.0.55.1")) { var leddimm = new Integer(txt_ergeb.get(1)) * 5 l_wozi.postUpdate(leddimm) } else

if (txtleer.get(i) == ("VAR.hue.event.hue=1")) {
cSofaecke.sendCommand("80,100,57")
} else

if (txtleer.get(i) == ("VAR.hue.event.hue=0")) {
Sofaecke.sendCommand(OFF)
} else
 
end

Und zum anderen um Befehle an die Domiq zu senden:

domiqsenden.rules

import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*
import java.lang.*
 
rule "Dimmed Light FlurEG"
when
Item l_flureg received command
then
var Number percent = 0
var Number percentd = 0
if(l_flureg.state instanceof DecimalType){
percent = l_flureg.state as DecimalType
percentd = (l_flureg.state as DecimalType) / 5
percentd = Math::round(percentd.intValue())
}
if(receivedCommand==INCREASE) percent = percent + 2
if(receivedCommand==DECREASE) percent = percent - 2
if(receivedCommand==ON) percent = 100
if(receivedCommand==OFF) percent = 0
if(percent<0) percent = 0
if(percent>100) percent = 100
postUpdate(l_flureg, percent);
if (percent>0 && percent<100) {
sendCommand(domiq, "LCN.output.0.16.2=" + percentd + "\n")
sendCommand(domiq, "LCN.output.0.10.1=" + percentd + "\n")
}else{
sendCommand(domiq, "LCN.output.0.16.2=" + percent + "\n")
sendCommand(domiq, "LCN.output.0.10.1=" + percent + "\n")
}
end
 
rule "l_esstisch an"
when
Item l_esstisch received command ON
then
sendCommand(domiq, "LCN.output.0.9.1=100\n")
end
 
rule "l_esstisch aus"
when
Item l_esstisch received command OFF
then
sendCommand(domiq, "LCN.output.0.9.1=0\n")
end

rule "rolladen sofafenster"
when
Item r_sofafenster received command DOWN
then
sendCommand(domiq, "rolladen.wozi.klein=down\n")
end
 
rule "rolladen sofafenster hoch"
when
Item r_sofafenster received command UP
then
sendCommand(domiq, "rolladen.wozi.klein=up\n")
end
rule "rolladen sofafenster stop"
when
Item r_sofafenster received command STOP
then
sendCommand(domiq, "rolladen.wozi.klein=stop\n")
end

 rule "Min- and Max values Wozi"
when
Item t_wozi received update
then
var Number Min
var Number Max
var String tmp
var SimpleDateFormat df = new SimpleDateFormat( "HH:mm" )
 
if (t_wozi.state instanceof DecimalType) {
Min = (t_wozi.minimumSince(now.toDateMidnight, "mysql").state as DecimalType)
tmp = (Math::round(Min.floatValue*10.0)/10.0) + " °C (" + df.format(t_wozi.minimumSince(now.toDateMidnight, "mysql").timestamp) + " )"
postUpdate(t_wozi_min, tmp)
 
Max = t_wozi.maximumSince(now.toDateMidnight, "mysql").state as DecimalType
df = new SimpleDateFormat( "HH:mm" )
tmp = (Math::round(Max.floatValue*10.0)/10.0) + " °C (" + df.format(t_wozi.maximumSince(now.toDateMidnight, "mysql").timestamp) + ")"
postUpdate(t_wozi_max, tmp)
}
end

An der Domiq muss man nichts ändern, die plappert vor sich hin und teilt alles mit Openhab. Somit kann ich z.B. in der Domiq einfach eine Variable erfinden
und diese z.B. durch einen Taster setzen lassen, z.B. VAR.hue.event.hue=1 Da Openhab das mitbekommt kann ich darauf eine Rule anwenden und somit z.B.
eine Hue Lampe schalten s.o. oder den Denon AVR und die Squeezebox anschalten etc....

[teichsta]

wow, dass ist abgefahren, ein Domiq-Binding in Rules implementiert … schonmal drüber nachgedacht ein "echtes" Binding zu implementieren? Rules sind ja eher schwer zu debuggen?

Moin Thomas,
mit der Binding Programmierung komme ich noch nicht so ganz klar.... Liegt aber vermutlich an meinem JAVA Skill
Sobald ich da durchschaue, werde ich das in Angriff nehmen Kann aber noch ein wenig dauern....
