In /etc/weewx/weewx.conf the driver is set to FineOffsetUSB - which pointed to
the (to me) most relevant station to my ECOWITT WS2910 station. But the ECOWITT
is a WiFi station - not USB. So I suspect I have linked up with the wrong
driver. Can anyone tell me which driver or clone system to my ECOWITT I should
be using. This is my first entry into commercial weather stations having
created my own Arduino or Raspberry Pi versions in the past - so am a bit lost.
I think you have two options:
a) use an SDR stick and try to catch the weatherstation directly at its
frequency (in europe 868MHz, etc....) - you will need something like
this: <https://github.com/matthewwall/weewx-sdr>
b) use (and buy) a GW1000/GW1100 from Ecowitt (that listens on that
frequency and provides a webpage) and use the gw1000 driver:
<https://github.com/gjr80/weewx-gw1000> - you will access the
weatherstation via your network and not over other radio frequencies.
I use the GW1000 driver myself and have never used a SDR driver for a
weatherstation - I have seen on other hobbies that running something
like rtl_fm to listen to frequencies with SDR sticks is a little bit
more CPU consuming than just fetching the data via WiFi (or LAN).
Regarding the webpage on your local filesystem: does it get updated or
what time does it mention, because i doubt it will be updated because of
the stopped weewx service...
