Spike Removal
Are "spikes" detected between subsequent reads from the weather station - i.e. the difference between readings 2-3 seconds apart? I have an intermittent humidity spike on my VP2 (it has been there for years) so am looking at using spike removal, but wanted to understand how it works first

Re: Spike Removal
See viewtopic.php?f=13&t=3857&p=32265
Although that was written for legacy Cumulus (which did not deal with spike on Davis), I would think the answer is yes for MX viewtopic.php?f=40&t=18560&p=147196 and Davis?

Re: Spike Removal
Correct, spike removal now applies to all station types, and it is between subsequent readings.

Re: Spike Removal
Does anybody have any suggestions / recommendations for spike removal values.

Re: Spike Removal
It depends on what spikes you are seeing. Personally, I have put in a humidity threshold of 4% in, as my weather station occasionally reports outside humidity momentarily 5% above previous and subsequent values.
I haven't set values for other parameters as I haven't experienced any spikes in received values.

Re: Spike Removal
Hi freddie,
It was more of a preventative measure I was thinking about. I did see one wind gust spike which I managed to remove manually a few weeks ago but normally things are quite well behaved.
