Good evening everyone,

I inform you that, at the following link, you will find a real-time map of all the Wittboy stations currently being tested by the selected beta testers, relative, at the moment, to Italy, Portugal, and France

https://umap.openstreetmap.fr/it/map/test-ws90_704295#4/51.12/-1.58

In the details, you will have access to the link of the Wittboy and the reference station used for the comparisons

I thank my friend Toby for the immense work and for the continuous updating of the map.

Beta testers who wish to appear on this map will be able to do so by sending me an email to

mauro.serenello@protonmail.com

I will send a pdf document to fill and to send me again when ready

Thank you all

M.

Looking forward to sending my beta station data when our nasty weather permits.

Thanks,

I've also made an overview of the measurements of the rain of the WH40 and the WS90:
 [ You are not allowed to view attachments ]

Quite clear to me is that the low intense rain events (25-2, 12-2, 8-2, 3-2) are not very precise. The long and heavy rain events (20-2, 16-2, 15-2, 6-2) are much more precise, and the deviation is 6% to as low as 1%.

Please note it is a comparison between the WH40 and the WS90. No manual rain is measured.

V2.1.1 upgrade is available for GW2000 gateway. The upgrade is:
normal rain gauge data and ws90 haptic rain data can be uploaded at the same time and you can view both rain values on your same dashboard. This gives you the possibility that you can view both rain data from WS90 and WH40(WS69) in paralell.
Haptic rain calibration can be adjusted according to different rain intensities. This will make it possible that you can fine-tune the rain accuracy for the WS90 wittboy sensor.

anyone know how to setting up the piezo gain ? For example: if I want to increase by +50% what is the correct value from 1.0 set by default?  [ You are not allowed to view attachments ]

[davidefa]

I'd say multiply the actual value by 1.5

Would be nice to know if the 'when rain rate less than' ( for 'Piezo Rain2 Gain', 'Piezo Rain3 Gain' and 'Piezo Rain4 Gain' ) means 'when rain rate between'.
for ex: Piezo Rain2 Gain affects all the rain rates less then 10mm/h or only the rain rates between 4mm/h and 10mm/h?

[Gyvate]

it only makes sense with ranges: =>
1. 0.00 -  4.0 mm/h
2. 4.01 - 10.0 mm/h
3. 10.01 - 30.0 mm/h
4. 30.01 - 60.0 mm/h
5. 60.01 - ....   mm/h
So in my understanding if the rain rate is inside of one of the 5 windows, the gain (=factor) of this window will be applied.
You want only 1/2 the amount to be shown, factor = 0.5
You want 1 1/2 times as much shown, factor = 1.5 etc.

Having 5 windows seems to be good for a start, but from my observations over one month with about 20 rain days, there should be a bigger granularity, especially in the lower rates. Rather 8 than 5 windows.

[wsNoordbergum]

It has to be the between rain rate values
Otherwise the multiplier would be the sum and that can't be right
Whenever a rain rate exceeds a value then the rate will be multiplied by the given threshold
So if rain rate is 6 then the multiplier value of between 4 and 10 will be used
This is the only way it makes sense

Still waiting for the ws2001 to be delivered, it has been delayed due to better calibration of the haptic rain sensor

[Gyvate]

with firmware 2.1.1 (released 03-Mar-2022) the GW2000 console/gateway ("hub") can display the WS90 rain readings ("piezo") and a WH40 rain readings with history in synoptic view, both in the WebUI or on the ecowitt.net dashboard.

[giusCB]

Anyone has setting up a different gain calibration?

[hiljo]

I'm trying with 1.2 in the lowest range. But currently no rain in the predictions 

[giusCB]

My idea of settings is:

1.5
1.25
1.0
0.85
0.6

If anyone wants to try...

For those who may wonder why I wrote firmware version 2.1.1 and the picture shows 2.1.0:
in order for the WebUI to show an updated firmware version also in the left hand side menu, one has to log out from the WebUI and log in again - only then the display of the correct firmware version takes place.
You can run with an updated firmware version higher than what is displayed .... - strange, but that's what it is

I still have to finalize my calculations with reference not only to the absolute rainfall per day but also with reference to the rain rate over the respective periods. Plus, my reference won't be the WH40 readings, even though they will show in the final table, but mainly the readings from the manual rain gauges I used.

From there I can already see that factors < 1.0 for the rates 30-60 mm/h and >60 mm/h won't be realistic. An overreading of the haptic sensor in the high windows didn't take place in my observations. (Almost) always an underreading.

Once the splitting of the daily readings into portions of different rain rates (and the comparisions to the different rain gauge readings) is done, I will come up with a proposed scale.

[giusCB]

the shippings seems to be start in a few days, so more public testing around the world

after the first downpour the measurement was 4.7 for wh40 5.4 for ws90, difference + 14.89% so, the proposing gain setting in this case was perfect (only in this case, we need much more datas)

Anymore conclusions on the offsets for piezo rain from WS90?

I have my Wittboy from my Kickstarter Order up and running, very nice piece of kit compared to the Weatherflow tempest. Its giving data to my site http://www.twinfirs.co.uk

My only real complaint is the app absolutely sucks, really bad presentation

[hiljo]

I see that the wire of the WS90 is white in your case? in the beta version it was black (in my case at least). A small hardware revision too

What app are talking about ?
The WS View Plus app ? The Ecowitt app ? The WebUI ?
Would be interesting to know ...

The Ecowitt App, this was the one I was told to download in the instructions. The information given on an iPad and iPhone is not in a great order, the layout is all wrong and far to big, to see the info given you have to scroll through four pages.

[Gyvate]

the WS View Plus app (also available for download on the Ecowitt web site: https://api.ecowitt.net/api/app/download?category=WSView%20Plus gives you a nicer view and control over your GW2000 console/hub,
however inside the local WLAN only.

The free version of the SmartMixin app might be a nice alternative to the Ecowitt app (have a look at https://www.wxforum.net/index.php?topic=43629.0).

Even though on an Android smartphone it (the Ecowitt app) doesn't look that bad as in your picture.
Maybe there's an issue with the iOS app - I suggest to send a message (email) to support@ecowitt.com and tell your story and attach the picture.
Their support is usually very helpful and supportive (as the name says  ).

I need to recalculate because the beta versions of wittboy record additional rain even if the hapitc sensor is damp or slightly wet. Ecowitt says that the kikstarter's version has an improved system to not active the piezo sensor with humidity.
