Only how do i get the unic code of the Sensors?
And the code: sudo modprobe w1-gpio is not working, or do i have first the sensor on it?
Can i make in this string the BMP085 on the same way?

I don`t think it can be connected in the same way. I don`t think it is an 1-wire device. However you can connect it to another gpio pin there are several available on the Pi

BMP085 talks i2c. The Raspberry Pi can talk i2c too after some modifications.

@ All,
It looks like that i bin there allmost..
1 question how do i get the uniqe id, from all the different sensors? Do I get this when i do this tutoriol: cl.cam.ac.uk/projects/raspberrypi/tutor ... mperature/
Is that id for always? or is the sensor evertime get a new id when i connect it to the Rpi?
How do i mark this sensor in Domoticz...? Or in my documentation.?

What is the limit of sensors?

I would like to learn a new application for home automation that uses 1-wire sensors (DS18B20, ds2438) Modbus instruments. domotic-dream is an opensource software like LAMP distributed for free under the GNU GPL3. domotic-dream preinstalled on raspberry and can be downloaded from sourceforge. anyone who wants to use or develop other plugins, to connect to http://www.domotic-dream.com or http://sourceforge.net/projects/domotic ... =directory
