once you make a timelapse, you could almost understand why I have extreme rainfall, without a single drop.
(but usually it just sways a bit in the wind without a lot of false rain)
What is very strange that the most zoomed in level somehow did reset all the rain before 17:40 but one zoom level higher it did not. Even more strange as this station is in the Netherlands and I don’t think it does raincheck in this region, so how did it reset, even partially (but it would be correct to do so, as there wasn’t any rain)
yeah it is pretty windy, with speeds over 60km/h, but I’m really puzzled why the rain is reset before 17:40 in the highest zoom level. Seems like a strange bug.
RainCast isn’t fully operational outside the US/Canada but there are more and more parts in this solution that will become active as time goes. And I just had a look and the system decided some was just not possible and wiped it. Maybe the blue bars should also be taken out this weird situation where it sees rain but doesn’t record any… will talk this over next week internally.
Indeed Near Cast should remove both the totals and the rate. Is there a way to toggle Near Cast on/off? I couldn’t find it in the app.
edit: Found it. it is in settings/stations//manage devices//advanced. @eric it is called NC rain (Near Cast)
Also, if Near Cast wipes data, it should have started the new accumulated rain values after 17:40 from the corrected value (zero in this case), not at 30.9mm.
It just got even stranger because it also wiped the data between 18.00 and 19.00, but not between 17:40 an 18:00. at 18:00 it jumps back from zero to 34.6mm.
Curious how it will handle 19:50 because now there is very light rain.
I have two, one does a dome view and is pointed straight up, and this one I can point in any direction. At night it does color pictures without IR illumination and I can see clouds that I can’t even see when I go outside and look up. (passing cloud at midnight. - YouTube taken at midnight). I can point the camera in any direction, and at some point in time I would like to couple it with the tempest, so it always points in the direction the wind is coming from. I love it.

(search aliexpress for a better deal). The specs tells you it has a very slow shutter speed of 1 second but that appears not to be true. The longest time is 1/3 second. Long enough to see the stars at night. (and it has a mode to create a moving average of the pictures, so the noise is very low).
so basically Near Cast is now working in the Netherlands as well, and it correctly identified a couple of periods with only false rain measurements. That is great news!
The implementation however is super buggy as it doesn’t use the corrected value after such a period, but instead just shows the uncorrected values again. Also it should correct the rain rate during such periods. When correcting data, it should also correct data at other zoom levels of the graph, not only at the highest zoom level.
The value on the history tab also needs correcting.
I DIDN’T say it is active, I said parts used by NearCast are active outside the US/Canada. And for sure it isn’t as effective for us outside the US/Canada. One day …
ok, perhaps only parts of NearCast are active in the Netherlands, I can toggle it on or off and the graph does change. I’ve no idea which other parts are not active. I’m assuming the name change to NearCast is in anticipation of other sensor data also possibly getting this treatment.
I don’t know why it couldn’t be as effective (or ineffective) outside US/Canada. We have excellent rain radar data, which could be used to filter out a lot of false rain events.
Having said that, to me it appears as a hack. If the sensor picks up wind as false rain, it is almost impossible to measure rain correctly when there is wind and rain at the same time. The real solution is of course to mount it properly, so it doesn’t see wind as false rain.
