Domotiga on KNX/EIB

Post by **prensel** » Tue Nov 10, 2009 4:20 pm

Hi there,

I've just managed to run Domotiga on my 'KNX/EIB enabled house'.

My Domotiga setup is:

- Targa Nettops (or Lenovo Q100) headless backend
- Ubuntu 9.04 desktop
- Gambas - latest version-
- Domotiga - latest version -
- Bluetooth interface
- NX Server

My KNX setup is:
- Merten USB/KNX interface
- Lots of Gira KNX actors
- Lots of Merten KNX actors
- (every, and i mean every wall outlet is switchable through KNX)
- Almost all (work in progress) lighting based on 12V LED (strip and replaced halogen units) , using 0-10V dimmable modules

Setup was a bit different then mentioned on the website (old versions of eibd and such) but it works now and looks GREAT !!

I made some small adjustements to Domotiga because I only use the KNX interface so the other 'tools' under the Tools menu are disabled unless selected in the Interface list.

I'm also planning to add and modify some more KNX stuff in the near future (tested modules, jpg and such)

Plans for the near future:
- touchscreen UI in all rooms
- heating integrated in knx
- security integrated in knx

Regards,
Paul

Can't see the pictures

Can you share how you installed eibd? I just use the 0.4 version deb packages that are on the eib site.
Input, bug and so on are very welcome.

Nice to see another KNX/EIB user on DomotiGa.

Timo.

My setup of eibd:

- fresh install of Ubuntu 9.04
- installed pthsem 2.07 by source
- installed eibd 0.0.4 by source
- recompile everything

I only use the usb module

I'll try to makeup a step-by step setup because all i could find on the net was based on older versions and i like to have a step-by-step for myself just in case i need to rebuild or restore a similar setup

Pictures of my 'work in progress house' will come this weekend.

I use the deb packages from http://www.auto.tuwien.ac.at/~mkoegler/index.php/eibdeb

Just add the repository and do a sudo apt-get install eibd

But I am a bit on the lazy side....[8D]

Today I got the new Elektor Magazine, with a few pages about X10, KNX and other Domotica protocols.

They mentioned the freebus project http://www.freebus.org which is a website about open source DIY EIB hard- and software projects.

Never knew that!

I have had 12 freebus dimmer and controler pcbs made in china.
Build to test them out, but still have to program the LPC900 microcontrollers.

If they work ok, I'll build the other 11. But I won't need all of them so a couple will probably be up for sale.

I'd looked at freebus also a while ago but finally went for Merten/Gira KNX hardware as main line.
Dimming is an expensive thing under any bussystem, around 100euro per channel for knx but I reccon freebus is a lot cheaper ?

I went for the 0-10 dimming route, so having only 0-10v dimmers (siemens has one cheap per 8-channel module) and PWM controllers driving the lights. LED's in my case but you can use the same setup for TL or halogen lights with cheap hardware.

Timo,

Did you make a new class EIB for Domotiga, thought I'd read it somewhere ? What did you change about it ?

After using/testing the current class module for some days I believe I found some errors. For some reason the module is not receiving all the datagrams from the bus as it seems so i'm planning on digging on the module this weekend but probably wont have to if you'd already changed things

Hi Prensel,
You have
I've just mailed the new code to Ron. I've changed most of the send and receive subroutines to use string arrays. Instead of plain strings.
Do you have any KNX device that uses the EIS3 and EIS4? (Date and Time).

I only have EIS1 and EIS2 devices installed at the moment, so testing the other EIS types is a pain.

Use ets in monitoring mode for those.

Timo,

Yes I have a Merten KNX yearclock hooked up. Do you want some ets output ?

Yesterday i've noticed that the eib class is interpreting group numbers different then shown on the ets monitor, did you took care of this in the new module ?
