Automatic turn on lights when the sun goes down (Tellstick)

[Filip]

This post will describe how to make your lights in your home turn on when the sun goes down and then turn off at a specific time.

Step 1: Preparation

Needed hardware:
1 Tellstick from Telldus (http://www.telldus.se)
Click on "Återförsäljare" to see where you can buy it
1-100 Rf receiver to your lights (compatible models at: http://www.telldus.se/wiki/index.php?title=Mottagare)


You need ftdi_sio.
(description stolen from: http://forum.excito.net/viewtopic.php?t ... ht=ftdisio)

Log in to a shell in bubba. Become root.

Code: Select all

apt-get update

and then

Code: Select all

apt-get install linux-modules

Step 2: Install the Tellstick

Put the Tellstick in the Bubba USB
To install the Tellstick:

Code: Select all

modprobe ftdi_sio vendor=0x1781 product=0x0c30

And then

Code: Select all

update-modules

Find where the Tellstick is mounted

Code: Select all

ls -l /dev/ttyU*

Go to:
http://svn.telldus.se/svn/tellstick/
Go to: trunk/rfcmd
And download the files in an empty folder

Code: Select all

make

/* Start troubleshooting
If you can't run the make commando, I think it will be solved by running the following two commands:

Code: Select all

sudo apt-get install make
sudo apt-get install build-essentials

*/ End troubleshooting

Code: Select all

cp rfcmd /usr/local/bin

Now test with: (replace USB0 with your own number and of course "NEXA A 1" to reflect one of your devices)

Code: Select all

rfcmd /dev/ttyUSB0 NEXA A 1 1 

And turn it off with

Code: Select all

rfcmd /dev/ttyUSB0 NEXA A 1 0

If you are having ownership problems with the tellstick, run the following command (and change to your device number):

Code: Select all

chmod 666 /dev/ttyUSB0

If you now are able to turn on and off your lights, proceed to next step.
If not, then reply to this thread or go to www.telldus.se/forum/ for support.


Step 3: Make the lights turn on/off automatically

Copy and save the source code of sunset.php (included in this post) in /home/web/tellstick and make all necessary settings in the file


Use sun_class.php available from:
http://phpclasses.mkdata.net/browse/file/11404.html
And of course included in this post.
Save it to the same directory as sunset.php


Use

Code: Select all

crontab -e

Add the following line to the crontab file: (will run the file every 10 minute)

Code: Select all

*/10 * * * * /usr/bin/php /home/web/tellstick/sunset.php >/dev/null 2>&1

Save the file and exit the editor.

Finished!


Please give me feedback on the instructions!

Thanks!

Now I have to buy even more hardware...

[Filip]

I have a small addition to the instructions.
If the bubba is rebooted, it will not work. Therefor you will have to write the following commands to make it work again after a reboot:

Code: Select all

modprobe -r ftdi_sio
modprobe ftdi_sio vendor=0x1781 product=0x0c30
update-modules
chmod 666 /dev/ttyUSB0

[/code]

[adegert]

The URL for the rfcmd sources did not work, I got them from

Code: Select all

http://svn.telldus.se/

(Subversion Repository TellStick, trunc, telldus-core, tarball of rfcmd)

The command for the installation of the build environment should be

Code: Select all

apt-get install build-essential libftdi-dev

[hawkman]

Hello,

I am trying to build the rfcmd. When running make, I get the error:

Anyone could point me in right direction?

Should probably be "`-L/usr/local/lib" instead

Hi,

Thanks for your reply. I tried to change that in the Makefile, but still got an error:

gcc -O2 -Wall -I/usr/local/include -o find_telldus find_telldus.c -L/usr/local/lib -lftdi -lusb

find_telldus.c:35: error: dereferencing pointer to incomplete type
find_telldus.c:38: warning: implicit declaration of function `ftdi_list_free'

I have updated the linux-modules, and when I do

Code: Select all

modprobe ftdi_sio vendor=0x1781 product=0x0c30

I just get back to the prompt (which I guess is ok).

When I run update-modules afterwards, I gett

Code: Select all

Architecture-specific modutils configuration not found, using defaults

. Do I need to change any other configuration regarding this?

Suggestions are much appreciated

You need a newer libftdi for that but you should be ok as long as rfcmd was built successfully (find_telldus only tries to detect the stick, normally you don't need that).

[hawkman]

Hi,
Thanks for your reply!
rfcmd is not building. The make is stopped due to errors as stated above. So I should try to update libftdi?
How do I do that? I have tried to apt-get install libftdi-dev but there does not seem to be any newer.

/H

[hawkman]

No other things I could try?
I am really stuck here...
Perhaps someone can provide the rfcmd binary compiled for bubba?

[hawkman]

Hmm. All of a sudden it is working

[tor]

Hi all,

Cool howto, nice work Filip. I have a short question, does anyone of you know of a device such as the Tellstick but with a receiver as well? Reading up on this the Tellstick only has the sender part. I would be interested in for example to read out data from weather station sensors etc.

/Tor

[6feet5]

Hi Tor,

I've been searching for a receiver as well. The closest I got was a description on http://wiki.nethome.nu/doku.php/modupm. This one uses the base unit of a wireless thermometer as the receiver. I bought one from ClasOhlson, but haven't had time to try it yet. I'm thinking of building a new USB device and hook it up to one of these. Perhaps not the most beautiful solution, but if that is what it takes...

I actually had a receiver in the NEXA transmitter I built, but the signal was far too noisy, so I never managed to figure out how to decode it.

/Johan

[6feet5]

I just remembered I actually did find a couple of receivers while searching for antennas, but they were a bit too expensive for me. Unfortunately it seems I forgot to bookmark the page (I think it was a german company), but I did find this http://www.cheapertronics.com/product_d ... item_id=25. The devices look a lot like the ones the german company had. Price is about the same as well.

/Johan

[tor]

Hi 6feet5,

Thx for the reply. I think i have seen the device that you linked to unfortunately that one only has the receiver part
