Heat Sensor in Fortinet equipment

Hi all

We have lots of Fortigates and such , and we are looking at the heat sensor and trying to build alerts, however the temp sensor seam to get High and low states but these are all over the place, even between boxes. Where is this set and where is libre getting these values.
Its hard to have a global sensors for many many boxes when they all give different High values ?

For fortigate os, temp sensors (i’m assuming that’s what you mean) is auto calculated from the current value at discovery time.

If we can get the high/low values back from the device and you know the OID then we can update detection
