Hi OpenHabers,

here i would present you my little project to build a remote for my Settopbox (Satreceiver).
I use here a Coolstream Tank Settopbox. Its running with a Linux OS from the Tuxbox Project.
And the GUI is Neutrino.
https://wiki.tuxbox-neutrino.org/wiki/Kategorie:Hardware
The OS contains also a Webserver “nhttp” with a API
https://wiki.tuxbox-neutrino.org/wiki/Neutrino#Der_Web-Server_.28nhttpd.29

With the exec and the http binding
on OpenHab you will able to receive and send commands to the Reciever.

Here my coolstream.items:

String Coolstream { http=">[*:POST:http://192.168.2.116/control/rcem?%2$s]" } // receive the string from the sitemap for remote
String Sender "[%s]" {channel="exec:command:getsender:output"} // receive the Station String from the script
String Sendung "[%s]" {channel="exec:command:getinfo:output"} // receive the Programm Sting from the script

Here my exec.things:

Thing exec:command:getsender [command="/etc/openhab2/scripts/./getsender.sh", interval=15, timeout=5] //script call
Thing exec:command:getinfo   [command="/etc/openhab2/scripts/./getinfo.sh", interval=15, timeout=5] // script call

If you send this to the box:

http://192.168.2.116/control/getchannel?format=json&epg=true

You will receive a json answer like that:

{"success": "true", "data":{"channel": [{"id": "c4c404530001445d",
"short_id": "4530001445d",

To get from the box the current station and program, i used two scripts and the exec binding.

First, two scripts that get me the channel “name” and the “description” part from the Json request:
These scripts are stored in /etc/openhab2/scripts/ and must be made executable via the console with the command “sudo chmod 755”.

getsender.sh:

#!/bin/bash
curl -s 'http://<yourboxip>/control/getchannel?format=json&epg=true' |perl -ne 'print "$1" if /name": "([^"]+)"/'

getinfo.sh:

#!/bin/bash
curl -s 'http://<yourboxip>/control/getchannel?format=json&epg=true' |perl -ne 'print "$1\n" if /description": "([^"]+)"/g' |head -1

And here the part from my sitemap:

    Text      label="Sender"           item=Sender        icon="none"
    Text      label="Sendung"          item=Sendung       icon="none"
        Switch                             item=Coolstream mappings=[KEY_POWER="POWER",KEY_MUTE="MUTE"]
        Switch                             item=Coolstream mappings=[KEY_EXIT="EXIT",KEY_HOME="HOME",KEY_OK="OK",KEY_EPG="EPG"]
        Switch                             item=Coolstream mappings=[KEY_INFO="INFO",KEY_UP="UP",KEY_DOWN="DOWN"]
        Switch                             item=Coolstream mappings=[KEY_LEFT="LEFT",KEY_RIGHT="RIGHT"]
        Switch                             item=Coolstream mappings=[KEY_RED="RED",KEY_GREEN="GREEN",KEY_YELLOW="YELLOW",KEY_BLUE="BLUE"]
        Switch                             item=Coolstream mappings=[KEY_PLAY="PLAY",KEY_PAUSE="PAUSE",KEY_RECORD="RECORD",KEY_STOP="STOP"]

I looks in the sitemap like that:

Have fun with it.

Could you post a link to your project rether than a generic landing page, thanks

And here if you want how to add the channel list and “zapp” with selection in the sitemap:

item:

String Programme { http=">[*:POST:http://<box ip>/control/zapto?%2$s]" } // zapto is the call for the receiver to zapp

“zapto” is Neutrino unique. Other can differ.

and this is for the sitemap:

Selection label="Senderliste"      item=Programme  mappings=[<sender id>="DMAX",<sender id>="n-TV",<sender id>="WELT",<sender id>="N24 DOKU"]

“sender id” is the placeholder for the sender id, mostly a digit. That can be read out of the bouquet

Have fun.
