Device status based on universal device poller value


I'm trying to build a NOC view, containing all basic infrastructure. Besides the usual Net and server devices, I would like to show physical infrastructure status, i.e. the state of temperature, UPS, generator etc.

Ideally, I would drag the device onto my map, and have the state (device color) be dependent on some threshold values for e.g. the reported temperature. As it is now, the "Temperature" device is green as long as it simply answers - no matter if the answer is "There's 100 degrees celsius in the datacenter" emoticons_happy.png Is there any way to achieve this ?

Alternatively, can I add a graph to a NOC view page, showing the values reported by the temperature sensors via the universal device poller ?

Thanks for any thoughs and input on this,
