Low Temperature readings

Every few months I get a single low reading of -30C. This wrecks my all time records, all I can do is overwrite it with a guess. I suspect that it will prove hard to locate the cause. A simple filter in software would really help with this - a test to ignore single readings where the temperature change has been improbable based on recent history. In every case where I have seen this the curve looks smooth, usually positive deg, then a singe -30 reading.

Thanks

The 'spike removal' setting in the Calibration settings?

Brill, perfect - I've been using this for years and never noticed it. When did this feature arrive?

In 1.9.1, on the calibration screen. But the temperature spike removal was available by editing the cumulus.ini file for some time before that.
