One of the questions at the muug meeting today was about temperature and humidity readings/monitoring.
The 1-wire devices are quite easy to use .. there are a few links I've saved from prior here: http://delicious.com/ve4drk/1-wire -- they're about a year or so old ...
an interesting take is using the owfs (http://owfs.org/) with openWRT ( http://openwrt.org/ ):-) yes -- you know it can be done :-)
I know another local who has used these .. he has a nice display and info on how to do it .. it is: http://www2.ertyu.org/temp/conditions.php

Thanks for the links, Dan. Looks like a build-your-own solution, but I was hoping for something a bit more turn-key. Jun Ma recommended (via private e-mail) the HWg-STE, which appears to be a small, network- attached box that accepts 1-wire probes. He included links to their international web site (hw-group.com), as well as the Canadian distributor (hw-group.ca), but no prices are listed. I've e-mailed the Canadian site, and will see what the price is.
Brad Vokey's brother, Gord, recommended the TemPageR 3E, from AVTech.com, which I had also already come across. but their US $195 package includes a temperature-only probe. To get humidity as well, I'd be looking at more than the US $199 for the MicroGoose from ITWatchDogs.com.
Other options I've found include the Newport (newportus.com) iTHX and iTHX-SD, and the NetworkTechInc.com EnviroMUX-Mini, but they're more expensive as well. Someone I know at U of Calgary recommended a cheap solution that came out of there called Phidgets (phidgets.com), but it's also a build-it-yourself type of solution, which would also require some programming. (More effort than I want to put into it now, or that I can justify doing on work time.)
I'm thinking I'll order one MicroGoose from ITWatchDogs.com, and try it out. If it doesn't do what we want, I can try other options later, and we've only lost a couple hundred dollars.
Thanks to all who replied or offered suggestions at the meeting.

Just heard back from them. The price is US $195 for the HWg-STE with a temperature sensor, and an additional US $105 for the humidity sensor. Looks like the MicroGoose is still the cheapest way to go for a packaged, plug & play solution.
The ITWatchDog device is neat as is the WeatherDuck. As long as the device speaks SNMP that's all you really need.
We have used the APC NetBotz (new name for the product) in the past as well as something called a NetTherm from NOFWare (http://www.neurotica.com/wiki/NetTherm).
You can even salvage a bunch of those AVR Butterflies (they already have a thermister) and poll via serial (did that at my house for a while). Sounds like a good assignment for the RealTime Systems students. Free labour/research. :P

I had a hard time even figuring out their product line from their web site, but it looks like pricing _starts_ at over US $500, so there are numerous cheaper options.
as well as something called a NetTherm from NOFWare (http://www.neurotica.com/wiki/NetTherm).
We tried ordering from them back in 2006 (after Shawn Wallbridge recommended them, and they were almost the only game in town in that price range), and after almost a year of delays and excuses, we cancelled the purchase order. I don't think we'll try them again.

Did I mention that I want something quick and easy, that we can count on to work reliably? ;)
