I'm sure if you peruse the archives, you'll see that I post about this about every year. The answer to your question is 'No, I haven't found what I am looking for yet.' However, the quest I am on is slightly different. I am looking for a device that meets the following criteria. a) Reasonably small. This probably wouldn't be rack mounted; it'd be wall mounted, desk mounted, celing mounted, etc. b) Powered by PoE. c) Is SNMPable over Ethernet. NOT RS232 or serial, or anything archaic like that. Not MODBUS. It's 2004, people. d) Provides Temperature and Humidity. e) Has 4 or so input contact sensors (connections to AC units, etc.) f) Has 4 or so output contact sensors.
