group(s)write

[vlietje87]

Guten tag,

ich kann in der Kommandozeile:
groupswrite ip:127.0.0.1 0/2/1 1
und
in logic/*.py
sh.knx.groupswrite('0/2/1',1,'1')

Dies ist kein Problem und arbeitet ok

jetzt mein problem!
wie kann ich dies tun in meinem eigenen Skript Zufalls

Entschuldigungen für meine wunderbare Deutsch
Vielen Dank im Voraus,
jonas

In english

i'm trying to create a random script where i can do a groups-read or -write to a specific groups address.

But when i do this in my script "groupswrite" or "sh.knx.groupwrite" i get a syntax error or invallid command.

in de logics/*.py , sh.knx.groupwrite works becauze is it loaded from smarthome. And groupswrite works only in command line :s.

I've a project running next to "smarthome.py" where i want use these command in a script, so i can import this script in my project and read/write to the knx.

Thx

ok, and your script is written in which language? Shell/Bash, Batch, Python,...?

You have an example or a part of your script which fail?

[vlietje87]

Its writen in python ( and no errors ), just as smarhome.py.

It's based on the plugins/knx/__init__.py , there is the groups-read and write defined.
I've also imported some libs just as smarthome did.
I don't even know if this is possible but i tought i went close.
Despite i've no errors, it does nothing when i run it

[vlietje87]

this is part of my script:

#!/usr/bin/env python

import signal
import sys
import os
import subprocess
import asyncore

import dpts
from configobj import ConfigObj
import lib.my_asynchat

KNXREAD = 0x00
KNXRESP = 0x40
KNXWRITE = 0x80

class KnxReadWrite(lib.my_asynchat.AsynChat):
_plugin_conf = BASE + '/etc/plugin.conf'
socket_map = {}

def __init__(self, host='127.0.0.1', port=6720):
lib.my_asynchat.AsynChat.__init__(self, self, host, port)
#lib.my_knxchat.AsynChat.__init__(self, self, host, port)
self.gal = {}
self.gar = {}
self._init_ga = []
self.alive = True

while self.alive:
if self.socket_map != {}:
asyncore.loop(timeout=1, count=1, map=self.socket_map)
else:
time.sleep(2)

def _send(self, data):
def groupwrite(self, ga, payload, dpt, flag='write'):
def groupread(self, ga):
def encode(self, data, dpt):
def decode(self, data, dpt):

def main(self,argv):
if argv == '-r':
print('lets read')
self.groupread('3/3/20')
elif argv == '-won':
print('lets make some light')
self.groupwrite('3/3/20',1,'1')
elif argv == '-woff':
print('lets put off the light')
self.groupwrite('3/3/20',0,'1')
elif argv == 'test':
print('works so far')
else:
print '*'
print 'usage: licht.py -r <read> | -won <write_on> | -woff <write_off>'
print '*'

if __name__ == "__main__":
objName = KnxReadWrite()
if len(sys.argv) == 1:
sys.exit("usage: licht.py -r <read> | -won <write_on> | -woff <write_off>")
else:
objName.main(sys.argv[1])

Hi Jonas,

puhh, sorry there are to many mistakes to help you in my limited time.

Why don't you use the shell command groupwrite(s) from the eibd?
Or SH.py with the network plugin, or....

Good luck.

so long

hi,

thanks u still had some time to read my post

i managed to write a message with:

from subprocess import call
call(["groupswrite","ip:127.0.0.1","3/3/20","1"])

but how can i read one ?
because "groupsread" doesn't return a value?

thx

[vlietje87]

hi,

I'm still struggling here.

I need the value of a groupsadres in my "random.py" script.

( this is to make control in my own websocket server. My Raspberry is the client and here i need the value to send it to my server)

But groupsread doesn't return a value, only triggers a read request.
And will be received by smarthome.py en send by the VISU websocket plugin ( if i'm right ).

Gruss,
jonas

To get the answer you have to type "groupsreadresponse".

[vlietje87]

thx very much "groupreadresponse" gave actual a response.

but when i do:
var = call(["groupreadresponse","ip:127.0.0.1","4/2/0"])
print(var)
it's always "0"

I probably have to struct.unpack () this:

Response from 3.1.3: 42 15 0A 3D
print(struct.unpack('>l',var))
struct.error: unpack requires a string argument of length 4

Response from 3.0.1: 01
print(struct.unpack('>c',var))
struct.error: unpack requires a string argument of length 1

[vlietje87]

I'll make a new post for it,
i guess it would be easier.
