Exclude out of range values: eliminate them on the fly?

I have sometimes out of range values, mostly on temperatures.
My temperature sensors are part of a 1-wire network.

Out of range ? temporary failures of the sensor itself (= 85 Celsius), reset of my 1-wire hub or my controlling plc.

I harvest those data through my plc and send them to hubitat via Node-Red.
If I don't filter them, I could have warning from HE rules (like "pond temperature too high" because obviously 85C is too high for a pond, I don't want to boil my fishes).

Following this, do you think it's better to manage the false temperatures directly through NR (filter them) before sending them to HE ?

Or another way (through HE after receiving them from NR) ?
