check out the BarioNet device at:
http://www.barix.com/en/datasheets/P...onet%20V17.pdf

It is an SNMP supported programmable device. Low cost; list is $295 I
think. Can be used for Server Rack environment monitoring: temp,
humidity, water, etc.. Also remote control possiblities as it has 4
digital outputs and two 5A relays.

Good luck!
