They're hard to find, at least inexpensively. I've found several systems for >$700 that have some nice features, including cameras (http://www.rackbotz.com/) and multiple wireless measurement systems (http://www.microstrain.com/WWSN.html) but they've all been slightly out of range in the cost department, or have been aimed at a different market than what I was looking for. Using the Cisco temperature MIB has been pretty much the standard to this point. After some extensive hunting a while ago, I found this: These guys make a nice (fairly) inexpensive module that I think wins the competition. It has a large number of measurement and switch inputs, runs a number of relays (built in) and seems to be fairly customizable. The bad news: it's not "native" SNMP and requires some sort of little C or Perl module to do screen-scraping. The vendor provides a sample MRTG script, so it can't be that hard. http://rms.nethop.net/ $395 plus a lot of features, including running on minimal voltage. I haven't purchased one of these yet, but they're close to what I've needed several times in the past, and I'm looking for excuses to purchase a few. Any of you who pick one up, I'd appreciate it if you could send feedback to me personally. It seems to me that there still is not any widely-advertised, inexpensive temperature gauge that is network-accessible (SNMP) which is surprising considering the amount of damage that can be done via overheating in a datacenter. [Note: before I sent this, I read Robert Boyle's followup message, which has some interestingly low-priced alternatives. Perhaps I have been looking in the wrong places. In any case, the RMS device has some additional features that may make it worth examining for the remote or low-voltage wireless sites that are starting to appear with some frequency here in in the Pacific Northwest American area.] JT
I've searched the archives, and didn't see anything current.
I am looking for a small, cheap, simply device, that can measure temp and be polled via SNMP. POE would be a plus.
Any pointers?
