Topic: WittBoy = GW2001 (station) = WS90 + GW2000 on Kickstarter & Beta test

[Autofill]

Hi, just wondering if one of you can check something. If you have the AC/DC power pack for the wittboy, and run it only on that with no batteries installed, what does the battery indicator show?

Im currently troubleshooting with Ecowitt about this. I have a low battery indicator on when running on DC power and no installed batteries.

Hi,
I'm using just the AC/DC Power and my battery indicator shows ~0,6V LOW (in red) at nights and starts rising as soon as the UV panel produces some Power.
I will install 2 AA Batteries in the meantime since ecowitt will hopefully fix this with a firmware update.

Thank you very much for confirming this behavior as this is what I'm experiencing exactly!

According to Ecowitt there is no hardware in the wittboy that can distinguish between AC/DC power or battery power, meaning definitely this would have to be a software or firmware fix.

Thank you for confirming this again at least now I know my unit is not defective and operating as designed.

There has to be something, at least in my thought process, as one would not want the heater activated on just battery power.

That is a good point you raise. Hopefully if enough people bring this to Ecowitt's attention then can resolve it sooner. Its no big deal, except having that low battery indicator warning.

Hi!

I’m actually pretty impressed with the temperature and humidity readings on the WS90 beta version.

It looks like the temperature value of the WS90 is more in line with reality.

With newer fw. version (1.1.9) the automatic algorithm for temperature correction was deactivated after a request by some Italian beta testers. As we know I'm banned from them so I don't have any more information. I'll ask to ecowitt what is their strategy about that.
Now with 1.1.9 I've a massive overestimate

So even with radiation compensation off in 1.0.9 is it still in that particular firmware that still compensates or is it raw sensor data?

Thanks,
tweatherman

Hi guys,
any recommendations to upgrade the ws90 to fw 1.1.9? Or is 1.1.7 good to go?

Thanks

Was hoping that was the case.

Yesterday I was able to update the WS90 to the latest software version.With the help of a forum colleague giusCB.  He stopped indicating the wind speed in the box and in the room in the absence of flow. I put it on the roof last night. This is how the measurement data looks like from 00:00 to 17:20.

WS90 and WS80 are 4-5 meters apart. WS90 is slightly higher by about 1 m. On two separate masts. The WS80 is next to the Barani MeteoWind and the WS90 is next to the WS68 Ecowitt.

The measurement results can be seen below. They are from WS90, WS80, WS68 and Barani Wind. In my opinion, the differences in measurement between ultrasonic and cup anemometers result from the measurement technology. For me, the differences between Barani Wind and WS80 rarely exceed 10 km / h. In light winds, they often report similar or analogous values. On the other hand, with increasingly stronger and especially sudden gusts of wind, the ultrasonic anemometer catches higher values. More than once Barani did not catch a short, sudden gust, while the WS80 caught it and showed values higher by about 10-17 km / h. We must remember that classic wind gauges can stop when the wind direction suddenly changes.

Not only this, cup anemometers by design only capture wind two-dimensionally (horizontally) while ultrasonic anemometers capture three-dimensionally and can catch tensors/vectors of the airflow in the third dimension which escape the cup anemometers' capturing. Simplified: cup = horizontal airflow; ultrasonic = horizontal plus vertical airflow.

[giusCB]

They use a particular method to record the <gust> value, I'm near to find what is the problem.
The difference will be always present, but never over 15-20kmh in same location

[giusCB]

Thanks for your work 

[Arkadiusz_w]

I wonder if the WS80 / WS90 are for sure aneneometers measuring in three dimensions.

These are for sure

This one is definitely biaxial, they are also single-axis.

[Rover1822]

I would think they are, within limits as there is an aperture on the WS90 so you can't get the full range, like upwards, downwards, but angles of those. I don't have a WS80.
The quick shift due to turbulence/direction change yes I'm sure they can handle.

this is a comparison during a windy day between ws68 and ws90 before and after the new beta fw. 1.1.9
The graph are the difference from reference (in this case the ws68, who always had good reliable data compared to other anemometers)

before

from a constant overestimate by (about) 15 km h (up to 32 km h) to a (about) 2 kmh  ( without any offset )

we've just some random peaks but the improvement is evident...all suggestions are well accepted 

[Autofill]

thanks for improving the product algorithm. Question I have is should I upgrade my firmware to 1.1.9 from 1.1.7?

Just wanted to follow up, Ecowitt cofirmed this behaviour that with no battereies installed in the Wittboy and running on AC/DC power only, it will always indicate "low battery". Since the unit is operating as designed, its not clear if they are going to issue a "fix" for this, since its not broken.....i guess im OK with this...I mean I could put battereies in it, but don't need to

My Wittboy (and other accessories including a supercap modified WH41) is actualy running off my off-grid solar system using a regulated 12VDC, fused  power supply https://www.wxforum.net/index.php?topic=43135.msg439334 and  12V 100 amp h heated Lithium battery, with 500 W solar system. I basically cut the wire at wittboy powerpack the end and connected via fitted terminal connector to the power supply. This is way better then having to have 50 ft wire from my house to my shed in the winters which can last many months.

It may be useful for some to know how Barani MeteoWind calculates, among others, gusts of wind. Today my WS80 measured a maximum of 19.4 km / h, WS80 after software update 18.4 km / h, WS68, 13 km / h, while Barani Meteowind 17.4 km / h.

It is clearly visible that the wind gusts are lower after the WS90 update compared to the WS80 and are more similar to the MeteoWind Barani.

https://www.baranidesign.com/iot-wind-open-message-format

Below are charts of the 4 wind gauges today

Barani I see that he lost one frame at 20:10. Something's not working well for this LoRaWAN

[tweatherman]

How are the temperatures with the latest firmware update? V 1.0.9 are right on with raw data settings.

Thanks,

I have the first version of the Beta WS90 unit and the GW2000. I noticed today that the cap voltage is reported in the custom upload having a value of 3.3:

Code: [Select]

  'stationtype' => 'GW2000A_V2.1.4',
  'ws90cap_volt' => '3.3',
  'ws90_ver' => '119',

Is this normal? Did Ecowitt used a fixed value maybe so there wont be a low battery message for the cap?

[Autofill]

For the release version, my supercap voltage fluctuates. It goes up to 5.3V during the day in the sun, and then overnight, it drops slowly to about 4.8V (or something like that), then goes back up to 5.3V when charged again.
