[solved]Connect to Brennenstuhl LAN Gateway 433Mhz

---

Hello all together,

i have a LAN to 433MHz Gateway from Brennenstuhl. Must be the same like Connair. Is there a way to controle my power switches with pimatic over this LAN gateway? I haven’t find anything in web.

Thanks for help.

well, i guess this is not possible (yet). there are no protocols / api for these gateways, at least i did not find any useful information on that.
but you can use homeduino to control your remotes! check the howto

don’t know if this will help developing a possible plugin
https://github.com/power-web/connair-webapp

I found this:

http://simple-solutions.de/forum/viewtopic.php?t=260

Web-App will be possible, too. So with shell commands i can controll this. But i hope there is a better solution then this.

@Swen I found similar information as part of Amazon product reviews which sometimes provide valuable information. One of the reviewers has written a php script which might be useful for experimenting. If you have a working solution based on a simple example it’ll be possible to write a plugin or extend an existing - possibly homeduino. If the scripted solution is good enough it would also be possible to integrate this using a ShellSwitch - see pimatic-shell-execute

Yes, this solution was an alternative chance to get control my power switches. Otherwise i use pilight and build a 433MHz receiver/transmitter.

OK thanks guy’s. Are there tutorials to write plug ins by myself?

@Swen My suggestion is to try ShellSwitch first as it is probably good enough for what you’re trying to achieve and it is a lot easier than rolling your own plugin. If you want to look into plugin development though, you’ll find more information at https://pimatic.org/guide/development/

Thanks for this all useful informations. I will give a try with shell commands first.

I get it to work. Thanks Mwittig!
This script http://my-palm.de/gw433 works nice with parts of my custom code. Now i can use execute commands like this:

lightsscript.php 01001 01000 1

And lights switch on. Thanks guys!

@Swen That’s great! Are you also able able to receive state changes, for example if you switch a socket using the remote control? I am not sure, whether or not this is possible at all with the LAN gateway.

Hm, no that is a point that i don’t stated yet. I think the LAN Gateway is only a transmitter. If you dont sniff the network, you will never be able to now which state the power switches has.

I dont give support for this script, but i hope it can help somebody if i post it here.

        }
}else{
        echo "To less arguments!\n";
}

$data = getallgets($_GET);
startcontrol($data);

?>

Now you can control via:
yourscript.php 11111 00000 1
for switch on or:
yourscript.php 11111 00000 0
for switch off.

Otherwise for those to add a device in config just do it like this:

{
  "id": "light1",
  "name": "Lamp Desktop",
  "class": "ShellSwitch",
  "onCommand": "/home/user/yourscript.php 01101 10000 1",
  "offCommand": "/home/user/yourscript.php 01101 10000 0"
},

Thanks for your support, i hope that i can give a little back of my experiences now.

@Swen It looks great to me. Thanks for sharing! Much appreciated.

Is there a good soul to help me with this from the very beginning?

You have my attention. Start asking with your issues.

@Swen
I have brennenstuhl 433 and i want to send commands to it with web-app and create timers on PC. I have abyss server installed and php on my PC. Can you tell me what next, what software do i have to use, …

PC? Or did you mean Pi?
