****** VoIP2FHEM or HOWTO control the FHEM with Asterisk ******
|
|
|
|
Description
|
|
* This is a HOWTO about the use of a VoIP-DECT-Telephone as a remote
|
|
controller for the FHEM-Devices.
|
|
The provided scripts are under the GPL.
|
|
|
|
The Goal is
|
|
-- Switching the FS20-Devices
|
|
-- text2speach, the Telephone reads e.g. the measured-temp
|
|
-- Possibility to start scripts with the Remote Telephone
|
|
-- AND EVERYTHING MUST RUN ON THE NSLU2 :-)
|
|
|
|
Technical Overview
|
|
* On the NLSU2 (or every other Linux Box) runs an Asterisk. This machine
|
|
must not be the machine with the FHEM. I bought the Voip-DECT-Telephone
|
|
Siemens Gigaset C470 IP (80.-EUR). It has a nice Webinterface and it is
|
|
possible to read in a self made telephone book.
|
|
The Asterisk calls depending on the dialed number a bash skript. After
|
|
that Asterisk plays two soundfiles < text >< value > in a loop.
|
|
|
|
The NSLU2 is a weak machine. It always only creates a soundfile 1x and
|
|
then stores it on the harddisk. A set of prebuild voices (e.g. digits
|
|
from -20 to 90) are included. Some scripts for creating soundfiles and
|
|
automatically the telephone book are provided too.
|
|
Installation
|
|
* Go to http://fhem.dnsalias.net/voip2fhem and download the files.
|
|
-- Install with your package manager asterisk, sox, espeak. On the NLSU2:
|
|
"apt-get install asterisk sox espeak".
|
|
-- Debian: activate asterisk in the /etc/default/asterisk
|
|
-- copy the scripts voip2fhem voip2fhem_create_telefonlist
|
|
voip2fhem_create_txt2gsm to /usr/local/bin/ and be shure that they are
|
|
executable (chmod +x /usr/local/bin/voip2fhem*)
|
|
-- You can find on http://fhem.dnsalias.net/voip2fhem prepared voices:
|
|
"tar -xvzf voip2fhem_voices.tar.gz -C /" and give the correct rights
|
|
"chown -R asterisk.asterisk /var/tmp/voip2fhem"
|
|
-- cp extensions.conf and sip.conf to /etc/asterisk/ and edit these files
|
|
and the bash script /usr/local/bin/voip2fhem
|
|
-- restart/reload asterisk (/etc/init.d/asterisk restart or asterisk -
|
|
r and then "extensions reload" and "sip reload")
|
|
Hints
|
|
* -- if there isn't the required soundfile then the NSLU2 creates it. This
|
|
needs minutes (example: the word "asterisk" needs 3 min). voip2fhem
|
|
stores this file and the next time it will be used.
|
|
-- Use the script voip2fhem_create_txt2gsm on a faster machine to create
|
|
the sounds. Usage: voip2fhem_create_txt2gsm "I love FHEM". The soundfile
|
|
is then automatically copied to /var/tmp/voip2fhem/
|
|
-- it is also possible to connect the ASTERISK with the rest of the world
|
|
(e.g. Sipgate, 1und1) :-)
|
|
-- for debug asterisk: "asterisk -r", "sip debug"
|
|
|
|
|
|
Have fun and success :-)
