Sure! Here you go. BTW, the sensors have stayed on now for ~ a day or so. They don't drop all the time, but it's happened enough that it's also not a one time thing.

Thanks!

Neither of those show the removal :( I know this will be a pain but we'll need to see one of those to be able to see what's going on.

I do expect it's the device not responding to the snmp request that's causing it though.

Yep, completely understand and agree. I can keep an eye out for it happening again ... but is there a way to get the needed info post-mortem?

Thanks!

FYI, happened yet again - I admit, not sure how to debug it. But one observation - it "seems" to happen when a sensor gets down near 0C => sort of appears like this triggers the sensor going away.

I could be wrong - just trying to help out!

Thanks!
