Hi,
For a while now I am busy with Homeseer and X10 Devices. The only thing I use right now is the lights in the livingroom.
Can somebody give me some information about 1-Wire devices. I want to read temps in a few rooms
Questions:
What do you need to get the 1-wire running the best way, do you need cat5 kabel? Can you buy 1-Wire also in the netlands.
Can someboy get me started on this?
Thanks

No, you don't need CAT5. 1-Wire only needs 2 wires. But using CAT-5 can be very handy if you also want to have power supply going to the same locations as where your 1-wire devices are. You can use the other wires, not used by 1-wire, for that.
For reading temperatures you could use the DS1820 from Dallas Semiconductor: http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2815
How to get started:
Well, go to Dallas Semiconductors, http://www.maxim-ic.com/1-Wire.cfm and start reading...
First of all you'll need an adapter to get your PC and 1-Wire bus connected. You can order free samples at Dallas (somewhere, I did it myself a couple of months ago). For example, I ordered a DS9097U-S09 adapter, a COM Port Adapter. Most other free samples are SMD, so unless you have the right equipment for that, don't order it. Practically useless.
And of course you'll need software, drivers and such.
I believe Homeseer has a 1-Wire plugin, so then you could probably get started by consulting a Homeseer forum. If you prefer to write your own programs, then take a look here: http://www.maxim-ic.com/products/1-wire/software/
You can get 1-Wire Temperature sensors (DS1820) at Conrad, www.conrad.nl, Part No. 176168 - 89.
Also Koning & Hartman, in Den Haag seems to be selling 1-Wire stuff. (so i've been told)
And you could try www.farnellinone.com.
I recently ordered some 1-Wire devices from Dallas there, don't know (yet) if i'll ever get them.
Also, check out http://www.hobby-boards.com/, you can learn al lot and buy some nice stuff there. I bought a 1-Wire counter there some months ago which is currently used for monitoring my gas usage (still in testing stage).

Hi Guys,
I agree with Digit!
Here are some additional links regarding 1-Wire.
There is also a 1 Wire network device called HA7net check it out on
http://embeddeddatasystems.com/page/EDS/PROD/HA/HA7Net
I am thinking about it to buy it i the near future.
Also a lots of 1-Wire devices at
http://www.midondesign.com/
http://www.aagelectronica.com/aag/
I think Midon is very cheap on shipping cost. I use the log08 from Midon as 1-Wire logging device, it can run standalone as well.

Hello Digit and Bwired,
Thank you, Thank You!
For the great information, I think I will give it a try and order some 1-Wire stuff. First I will read all the information. If I have more questions, I will be back for some more questions [;)]
Thanks Jan

I bought my 1-wire temperature devices from http://fi.digikey.com. If you are in the Netherlands then http://nl.digikey.com is naturally a better choice. The price per unit nearly halves at 50 pcs, so that's how many I got (at 1.8€/device). At fewer quantities they are about 4€/device. The delivery was really fast as the devices arrived the following day after I had ordered them, IIRC.
Note that there are different versions of the temperature sensor. DS18S20 and DS18B20, and the parasite only models. And also different package types for each of these. The DS18B20 is better than the DS18S20 and also cheaper (correct me if am wrong), so that's probably what you want.
(Update: Just noticed that the original posting was posted some time ago. Well, somebody else may have use of this information).
I am building a house and will place them everywhere. In each room I will have one in the floor, wall and ceiling. Mostly out of curiousity, but also for better heating control. I have heat water pipes in the foor. I will also place one on each pipe so I know the in going and out going temperature of each pipe. This way I can better control the valves for the pipes and the water temperature I should feed them with. Lower temp gives better economics, so the more seldom I need to close the valves the more optimized the temperature is. I will have no problem to get all 50 into use. [;)]

Hi Bjorn,
That's a nice project you are starting and very good for putting the 1-wire devices at use. I have heated pipes (water) in my floor as well. I have 1-wire temperature sensors for temperature floor heating in, floor heating out and also on the heating device I have 1-wire temp sensors for measuring temperature in and out. http://www.bwired.nl/Devices.asp Combined with different temperature sensors in all the rooms and also outside. I have a Xanura switch on the pump which controls the water circulation of my floor heating system. Normally this pump is running 24/7 and consuming lots of energy. If my heating system goes on, after 5 minutes the pump of the floorheating goes on as well, if the water out temperature is above a certain value the pump goes of because the floor is heated enough. And also if my heating device (thermostat) goes off the water pump for the floor heating goes off as well.
Thank you for the URL of the 1-wire shop, I didn't know that one, I Will make a sticky topic of all the 1-wire shops I know.

(Sorry, this is getting a bit off topic). About the floor heating. Don't know the right english terms, but I have about 20 pipes in the floor, each with it's own valve. Some are controlled by the same thermostat, however (about 8 thermostats). I'll start by letting the convetional thermostats control the valves and only have the 1-wire devices monitor the temperature. At some points I will control the valves myself with software based on the 1-wire device readings.
I have a pump that takes energy out of the earth (again, don't know the english term for a pump like this) from a 180 meter deep hole in the rock ground. The energy effeciency factor should be something around 3 (i.e. for each kWh of electricity I put in I get 3 kWh of heat). The lower the water temperture the higher the effeciency. At low temps the factor is over 4. I guess these pumps are more common here in the north.
The pump itself has quite a lot of logic itself, and controls the outgoing water temperature based on the returning water temperature and the temperature outside. All this can be tuned by the integrated controller. It has a small mono graphics LCD for control and monitoring. I would of course [;)]like to control all of the pump functionality too, but I think that will get too complex for now. It has an I/O for remote control but that is not publicly documented. [:(]
With the aid of the 1-wire sensors I should be able to callibrate the pressure in each pipe in the floor. If they are unevenly set, then the valves will be shut more often for some pipes than othes. The ideal would be that the valves are open all the time and temperature is controlled only by the water temperature and flow. If a valve shuts then it means that the water is unnecessarily high.
I am fortunate enough to build a house from scratch and have the ability to hide the sensors fairly well. I have a lot pipes in the walls and ceiling for cabling and cable shelves in the basement. I will someday count the exact amount, but I guess I have about 1km of cable pipes in the house (plus about 50m cable shelves). [:)] It is still work in progress, however.
