I tried to apply an offset but I immediately deleted it because the error is not linear, the problem is the gusts value, the real time one is quite allineated to davis' one.
Ecowitt says that they have tested the wittboy in wind gallery but all wittboy's data i've seen online has this problem  :oops:

in this case I don't know if there are offsets but the difference is evident here too

no secret - just seems as if Ecowitt haven't managed yet to put the upgrade link on their web site under the GW2001 (Wittboy) product

Maybe I need to mention that in the last two days we had very different rainfall and wind conditions - from no wind to 77 km/h and drizzle to strong rainfall, both accompanied by changing wind conditions.
The graphs of the two stations (HP2551 and GW2001) at ecowitt.net will make that clearer.

Anyone experiencing more rain on WS90 piezo gauge vs manual rain gauges and or any Davis tipping bucket type? Factory calibration on all rainfall rates on my end. This is totally opposite than what I was expecting with what others are saying.

Thanks,
tweatherman
Another event yesterday wet snow that actually triggered the piezo gauge. Davis tipping bucket 0.04”, manual 8” 0.08” and piezo had 0.15”.

tweatherman
Another rain event 8” manual 0.08” and WS90 0.32”

the WS90 reads solar radiation systematically about 22% higher than the WS80 - and crosses the max solar radiation for the time of the year and your latitude.
If you want to bring the WS90 reading down to the WS80 level, a factor (gain) of 0.77 is needed.
BTW - Ecowitt technicians check this difference - wondering what their consclusion will be - because here - with the same exposition - the highlander principle applies:
"There can only one".  ;)

Mine is accurate, I don't have this problem. My ws80 undersrimate the radiation

 Could you (please) tell to the engineers to do a firmware update to fix the gust reading?  :lol:

It's weird. I installed the standard software and still had an STM32 driver error. I had information that there are no compatible drivers for this device.
kurczę  ;)
let's see: krok po kroku
1. you unpack the zip file into the WS90 Upgrade(v1.1.7) Tool Kit directory
2. you install DfuSe_Demo_V3.0.6_Setup.exe
3. you go to C:\Program Files (x86)\STMicroelectronics\Software\DfuSe v3.0.6\Bin\Driver\Win10
4. you start dpinst_amd64.exe (as your Win10 installation is most likely a 64-bit installation)
after the installation completed you should see in the Device Manager under USB Devices (last entry of the device tree) the sub-entry "STM Device in DFU mode"
5. you go to C:\Program Files (x86)\STMicroelectronics\Software\DfuSe v3.0.6\Bin and start DfuSeDemo.exe
6. the driver should be shown in the firmware update interface on the top left
7. connect the USB cable with your PC and press the reset button (don't confuse it with the CAL button  8-))
8. continue following the instruction in the PDF file
good luck


RESOLVED:

It's a USB windows drivers problem:

I went back to STM Bootloader in Device Manager and clicked it to update drivers. Instead of clicking the top window to choose the directory for the driver (I tried that before and Windows said no need to change), I clicked the option below it to "search windows for devices with similar drivers". And guess what popped up! STM Bootloader **AND** STM Device in DFU Mode.

I clicked the DFU Mode one, it loaded and works

ORIGINAL:
I followed all of that. It shows up in device manager, but the DfuSe_Demo_V3 software does not see it.

There is an error. You need to connect the station in dfu mode before installing the driver, only after that you can install the correct driver (disconnect the station)

I did that. Windows simply chose the wrong driver.

My WS80 is also too low compared to the Davis (1.10*) but the UV was way too high (0.65*)
*calibration
Whats the newer WS90 radiation shield like compared to the WS80, i find the WS80 isnt good enough, ive seen the temp > +2C compared to the Davis but that could be in part due to the location of the Davis FARS being up on the Mast at about 3m.

WS80 compared to Davis probe in the homemade FARS is about +1C but I will be moving the Davis to the same location at 7ft and moving the WS90 to about 10m up the mast and getting an extra temp for lower down.

@Aircub:
your pressure is measured in the console (e.g. the GW2000) , not in the outdoor array (here WS90) - so the accuravy you observed regarding air presure compared to your nearest METAR station (airport) is due to a good GW2000 pressure calibration (provided the airport and your place sit on the same isobar).

Outdoor temperature can vary by a few degrees due to many microclimatic influences. If your WS90 shows the same temperature as a nearby airport, I'd consider that rather a coincidence than a sign of reading accuracy.

For reading accuracy you need a properly shielded reference sensor at the same location (place/height).
Comparing e.g. to a Davis temperature sensor in a FARS which sits 2m higher than the sensor to compare with  is no longer a proper reference.

For me, the measurement with WS90 is the same as with WS80. But I am amazed by Barani iot wind. At low wind speeds, the difference is usually around 1-2 km/h. It rises above 10-15 km/h. Often, when Barani Wind reports 18-19 km/h, WS80 / WS90 reports around 28-30 km/h. Barani boasted that their elliptical anemometer records wind speed more accurately and better than ultrasonic anemometers.

The nearby stations of the state weather service record values similar or even analogous to Ecowitt ultrasonic.

Recently, while crossing the cold front, Barani Meteowind measured 40,4 km/h, while WS80 / WS90 54 km/h. Analogous values as the Ecowitt ultrasounds were given by the telemetry stations of the Polish weather service.

The WS68 Ecowitt at that time reported 38.5 km / h.

For me, the measurement with WS90 is the same as with WS80. But I am amazed by Barani iot wind. At low wind speeds, the difference is usually around 1-2 km/h. It rises above 10-15 km/h. Often, when Barani Wind reports 18-19 km/h, WS80 / WS90 reports around 28-30 km/h. Barani boasted that their elliptical anemometer records wind speed more accurately and better than ultrasonic anemometers.

good job !!
ecowitt told me that with the latest update (on ws80) he changed the gust measurement criteria also on the ws80.
 I didn't get to try. But your comparision worries me ...  ](*,)
