<div>I am using a Netbotz 320 device in my network and DC's. I have linked them to Hobbit using MRTG and bbmrtg.pl for temp and humidity and alerting. Here is an example MRTG entry for a 320 Netbotz:</div>

<div><br>I'm using OneWire DS18S20 sensors from Maxim-IC.com to watch room and refrigerator temps in my wife's dairy at home. Right now it's a bit of a hack, with the sensors just soldered onto old phone cables, but it works just fine. The fridge seems to be maintaining about 25F while the room temp gets up over 85F.<br>
<br>I'm using digitemp to read the sensors, which can be hooked up to either USB or serial ports, though it's also possible to use owfs. The readings are fed to Hobbit via a custom script that generates NCV compatible data for graphing.<br>
<br>The bare sensors are about $5, and the USB or serial port connector is around $30. You can use any old ethernet or phone cable.<br><br>Ralph Mitchell<br></div></div></blockquote></div><br><br clear="all"><br>-- <br>'If my answers frighten you then you should cease asking scary questions.' --Sam Jackson
