T,

i agree, i use this wind-info for local, `simple` personal use, but i noticed that the data coming from this
WH24 station at 20m height is about 33% off (plus) compared to actual wind speeds from KNMI etc. (so in agreement
with the mentioned table).

I can of course apply this -33% in my mind ...

.
Toulon7559,

thanks for the reply.

The source for the little table above comes from this Dutch website:

http://www.hhofstede.nl/opgaven/examens/HAVOWB122006I.htm

but searching on Google, you will find many references like this Danish website:

I editted Rtl433.cpp again to also "look" at the available UV, UVI and Lux data and added the SendUVSensor
and SendLuxSensor.

After recompile Domoticz it showed the both sensors and after some fiddling it seems to contain accurate
UVI and Lux data, see picture.

Now waiting for a sunny day ...

.
Sigh....., i updated to V4.10893 beta, and now the WH24 wind and rain sensors are gone.

The Rtl433.cpp file still shows the modifications i put in, but they obviously are not "in" Domoticz anymore.

Need to recompile Domoticz again and stay away from updates.

Well, i needed to remodify Rtl433 ...

.
Suggested is a way (button) to adjust (correct / offset) the windstrength / windspeed /windgust values so they
can be set according to the height of the windsensor.

Normally windsensors suppose to be installed at 10m heigth, but often they are higher (or lower) where the windspeed is
higher (or ...

.
Concerning the "over the top" wind strengths measured yesterday (12 beaufort etc. while it really was max. 9 beaufort).
i found out that normal windstrength measurements are done on 10m heigth.

As this WH24 weatherstation is placed at about 20m heigth, there needs to be applied some corrections ...

.
I did a new domoticz recompile using:
https://www.domoticz.com/wiki/Raspberry_Pi_-_Build_Domoticz_from_source
from "Domoticz Source"

but now inbetween the "cmake..." and "make" of:

cd dev-domoticz
git pull
cmake -DCMAKE_BUILD_TYPE=Release CMakeLists.txt -DUSE_OPENSSL_STATIC="NO"
make

i ...

.
I editted the Rtl433.cpp under Dev-domoticz/hardware to include these headers:

wind_dir_deg
rainfall_mm
wind_speed_ms
gust_speed_ms

I used the already in Rtl433.cpp available wind_direction, wind_speed, wind_gust and rain statements.

Not changed yet are these headers:

uv (not included ...

.
Now running on V4.10856 (beta) but still Rtl433.cpp is missing these:

wind_dir_deg (not included)
uv (not included)
rainfall_mm (not included)
wind_speed_ms (not included)
gust_speed_ms (not included)
uvi (not included)
light_lux (not included)

Did a complete power off and this brought back the WH24 sensor, temp and hum only still.

Kees

.
Did an update to V4.10848 (from V4.10826) and now again i have no more Fine Offset WH24 sensor (neither temp.
not hum.) detected.

Same as when going to V4.10821, see 5 posts above.

I tried to recompile domoticz using the modified Rtl433.cpp, but it fails, see:

Thanks Blitt,

i am sure i also tried with V4.9700 in the first place, see my 2th post above, but only the temp/hum sensors was seen.
But i will try to use your rtl433.cpp file, thanks a lot.....


Kees

Update to V4.10826, the WH24 temp/hum sensor is back.

Not sure though if it was a temporary hickup of the WH24 sensor or a change in the Domoticz code.

Anyway, still figuring out why not more sensors of this WH24 weatherstation (wind / rain / uv) are reporerted.....

Kees

Hmmmm,

since my update to V4.10821 this morning i don't see the Fine Offset WH24 sensor subtype WTGR800 (temp. nor hum.) anymore.

What was changed to cause this?

Looking at rtl433.cpp

(https://github.com/domoticz/domoticz/blob/development/hardware/Rtl433.cpp) ,

do i understand correctly that presently we "look" for:

time (start line 107),
unit
channel
battery
temperature_C
temperature_F
humidity
pressure_hpa
rain
rain_total
depth_cm
depth ...

.
Did a new installation on an USBstick.

latest Raspberry code, latest Domoticz code, latest RTL-SDR code and latest RTL433 code.
Now i see the domoticz/hardware directory with in it RTL433.cpp etc.

Now to find out how to debug this.....


Kees

.
I am unable to locate Rtl433.cpp or Rtl433.c on my installation.
Also the Domoticz/Hardware directory is not there, so i wonder if my Domoticz installation is somehow not complete.

I will build a fresh setup on an usb stick to see if it will contain those now missing items.

Kees

.
Thanks gizmocuz,

but the headers presented by the Fine Offset WH24 are already known in Domoticz, see picture (below) of the cleaned up
"WH24 data.xlsx" i attached earlier.

I will take a look at RTL433.cpp/h

Kees

Thanks for the info Jeremob.


Running at V4.10724 since today, but still no extra sensors seen.

Hoping for a solution too.
