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

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

Re: Low Temperature readings
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.kayjay wrote:When did this feature arrive?
