This is a really broken design. I have seen a similarly broken design in the AVTech Roomalert devices. However, *decent* environmental monitoring devices, that have a sane SNMP data model, are the Netbotz (http://www.netbotz.com/products/appliances.html) devices (for which I will commit a template soon).
