Guys,

As far as I can see from the thread this would be the steps for the 1-wire support. I unfortuanately dont have an interface unit.

1.Do a sqlCVS update from the webadmin. Select only tables within DCE.

Did you select all repos, or did you select all tables within dce? Make sure to not do the former, but only the latter

2.Install mysql devel headers

you need to install mysql devel headers (iirc "apt-get install libmysqlclient-dev" or something like that)

br Hari

3.Install OWFS. These are the steps I used, Maybe TEchstyle can post his steps. Or Hari could you point us to the correct steps of installing OWFS.
http://www.mail-archive.com/owfs-developers@lists.sourceforge.net/msg04821.html

4.Compile OneWire Binary

yes, and after installing owfs, you need to do something like the following to compile the binary:

Code: [Select]

sudo -i
cd /usr/src/
svn co http://svn.linuxmce.org/svn/branches/LinuxMCE-0810/src LinuxMCE-0810/src
cp /usr/pluto/lib/* LinuxMCE-0810/src/lib
cd LinuxMCE-0810/src/OneWire
make bin
cp OneWire /usr/pluto/bin

br Hari

5.

Techstyle, you also need to do a "echo /opt/owfs/lib > /etc/ld.so.conf.d/owfs.conf", followed by a "ldconfig -X"

6. Add the sensor in webadmin. We still need to confirm, where to retrieve the sensor's ID from.

Hi Folks,

I did write a DCE device for the owfs 1wire driver. Device Template #2161. The code is here: http://svn.linuxmce.org/trac.cgi/browser/branches/LinuxMCE-0810/src/OneWire/

Just create "Multilevel Sensor" Childs and put the 1wire ID into the port/channel field. The DCE device will store the last measurement and only send events when things have changed. Only temperature sensors supported atm:

35   01/19/11 11:11:30.628      Temperature for 28.B3795602000: 25.62 <0xb78c9b70>
35   01/19/11 11:11:30.628      Old temperature for 28.B3795602000: 25.56 <0xb78c9b70>
07   01/19/11 11:11:30.629      Received Message from 233 (1wire temp / ) to -1001 (unknown / ), type 2 id 25 Event:Temperature Changed, retry none, parameters: <0xb2cfdb70>
07   01/19/11 11:11:30.629        Parameter 30(Value): 25.62 <0xb2cfdb70>

br Hari

Anyone feel free to add to this or change anything accordingly. Once we get the installation procedure correct, I'll update the Wiki.

...

can I get ssh access to your system?

br Hari

[_if_]

jep, will set it up as soon as I get home...

[_if_]

should remote ssh be working at the moment? If I try to enable it, the webadminpage starts loading but never stops...

[hari]

does not work atm

[_if_]

does not work atm

do you have any advice what I can try until remote ssh is working again?

[hari]

regular ssh?

[_if_]

regular ssh is set up, you got mail!

[hari]

there is some problem with your interface. What exact kind is it?

I've added some more error handling to the code:

I've tried owfs and get the same problem. You need to make sure that your interface runs nice with owfs before trying the OneWire LinuxMCE driver.

br Hari

[_if_]

it's the totally same interface as I send to you...

[hari]

weird...

did you connect a temp sensor?
