Hallo Werner
Die API Doku enthält z.Zt. noch Fehler. In Kürze sollte eine korrigierte
Version erscheinen.
nachstehend die gültige und korrekte Fassung des CMD_READ_RAIN Befehls
und der "WiFi" (besser API) Rückmeldung
CMD_READ_RAIN 0x57 und die dazugehörige WiFi response (es gibt darin
keinen hourly rain - dies[er] wurde in Rain Gain umbenannt für den
WH40/WS69 Anteil [0F] bei Anmeldung von traditional und piezo am GW2000
[oder auch mitterweile GW1000 und GW1100 und WH2650 mit Firmware
1.6.9/1.7.0) - piezo hourly gibt es ebenfalls (noch) nicht

My modified driver from Gary (now named gw2000.py) supports the GW2000
and GW1100 with Firmware V2.1.3 (piezo_rain)
https://www.pc-wetterstation.de/weewx/gw2000.zip
The piezo_gain_values are at the moment not supported.
The hour piezo rain and hour rain aren't right, the pdf-docu isn't
here correct, seems this values are gain factors
I use the hail database value for piezo rain (WS90)
[[field_map_extensions]]
rain_piezo = rain_piezo
erain_piezo = erain_piezo
rrain_piezo = rrain_piezo
hrain_piezo = hrain_piezo
drain_piezo = drain_piezo
wrain_piezo = wrain_piezo
mrain_piezo = mrain_piezo
yrain_piezo = yrain_piezo
hail = rain_piezo
hailrate = rrain_piezo

Hi Gary,
I have abused my credit card and ordered a WH40 rainfall sensor
(along with the AQ & lightning sensior), so that readings from
both it & the piezo sensor can be compared. Will let you know when
it turns up and is installed.

Hi Gary,
I've just set up weewx with the gw1000 driver, and it appears
to have picked up the gw2000 just fine - I'm getting
observations coming in. I'm reassured, as a recent git pull of
the rtl_433 code doesn't decode anything from the sensors at
all, and while going down that rabbit hole of banging on the
code would be entertaining, I'm pretty sure that more
talented minds than mine are already on it.
I currently have the WittBoy (with the aforementioned piezo
rain detector) only at the moment, although I'm planning on
ordering the indoor & outdoor air quality sensors, as well as
the lightning one. This thing seems to be head & shoulders
over the AcuRite Atlas I was using with the SDR driver (plus
scraping pressure off the webpage on the Atlas hub).
Please let me know if I can test any code for you.

The current GW1000 driver will speak to a GW2000 and
should return all obs except for WS90 rain and WS90
signal/battery states. I am working on the v0.5.0 driver
but the behaviour of the GW2000 API with various
combinations of the 'traditional' and 'piezo' rain gauges
(Ecowitt's terms) is not very clearly defined. I will
likely need some assistance from GW2000 users with various
rain gauge combinations to tie this down. WS90 signal and
battery states are already working in the v0.5.0 driver.
Not sure how long the piece of string is.

A little searching here seems to indicate the gw1000
driver should possibly work for you. Give it a try

From the web page the device serves up, it appears
you can tell it to upload data in ecowitt or
wunderground format to your own server/port.
