  Yes, My one wire system has been running since 2006 I have never used VB6 Everything I have ever done was in VB.net using visual studio

Did you figure out how to switch each relay? I have one of Eric's 4 relay boards. Not sure about OWFS, never used it, but in VB.net you use container29 and this is how I switch relay 0 on the board Owd6 is a variable that I am using for container29 DS2408LatchChannel = 0 in this case for relay...

You might also want to check out Direct Buriable Cat5 cable if you need to run it outside. I used it on a long run to a green house and it was great not having to bury cable in a pipe.

Eric's hubs are nice because they provide a solid level of power to all the 1 one devices. Not sure how well that serial adapter does in that regard. I have used the usb adapter also, but it has a very limited amount of power it can supply. I don't like to run 1 wire sensors parasitically, I...

I have used several types of wire cat5 - regular cat5 -direct buriable Cat 5 is great for long runs and you have enough wires to run +5vdc, +12vdc, DQ and grounds solid core telephone cable - not good for long runs but just fine for making DS1820 temp sensors on the end of a short wire. If you...

They sell direct buriable cat5 cable. I used 100ft of it to go out to my greenhouse. Way easier than sch40 pipe and regular cat 5. do a google search for direct buriable cat 5

I use Wserver for my web weather station and my own custom software for things like green house montoring, etc. http://henriksens.net/1-wire/ Wserver also does FTP uploading to your web site and it reports to several weather services like weather under ground if you set up an account. Wserver...

How about looking at automotive O2 sensors. They output a voltage level based on the O2 in the exhaust? You can measure and report the voltage with a DS2438 and a few parts. I recently read some info on the web on a gadjet you can buy that lets you set the O2 sensor level to use with a...

Well I do not know where the Vsens value is being set, but you can set it for the DS2438 current calculation. The value is not set forever, the DS2438 will revert back to a 50 milliohm default You have to set the IAD flag to true and then set the vsens value just before you ask the DS2438 for...

Eric, You can set the vsens resistor value in a DS2438. Once you do that, you can ask for a current reading across the vsens resistor, which is an internal calculation of the voltage drop across the vsens resistor. I don't think this is widely known, seems to be so far. See the object browser...

You can turn things on and off with X10 devices also. The X10 programs lets you build macros that make decisions. Problem is, it's not as reliable as one wire, and there are not many sensors, except for motion detectors. I use a couple x10 powerflash devices here that turn on a x10 code when...

Thanks Eric, Perfect expecting rain tomorrow, better get outside and get it hooked up. Thanks again

http://datasheets.maxim-ic.com/en/ds/DS2438K.pdf You are a very strange person. Now where is that ignore button? Oh yes, there is it. Click!!! :o

Listen, I think we have a language probelm here. If you are interested, please read the DS2438 data sheet. http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2919/t/al Here's a snipet from the data sheet The DS2438 smart battery monitor provides several functions that are desirable to carry in a...

Eric, Got the new Ds2423 board for my rain gauge. I forgot to write down the wire hookup for the reed switch. Do you short the B or A terminals to ground to get a count or do you send the the input high to get a count. Where does the reed switch wire go? :blink: Thanks
