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).

Hi

 

Thanks for the reply, both of you. I had already found out that the snmp setup for this unit is stupid regarding branch/leaf setup, but managed to get it to work and graph with some efforts. But only to the trends page of xymon, not the temp test page itself.

 

These units can also be ued with xml and my next try will be directed at that I guess. 

 

Will there be a new test release soon of devmon?
