Interceptor Driver for GW2000 with WS90 - no rain

[chin0x]

Hey guys,

I've been going through some discussions but not quite sure if I did everything rigth.

Due to the circumstances that the GW1000 Driver is all of a sudden not available anymore, I decided to use the Interceptor driver when I changed from "Simulation" to "Productive" mode yesterday evening.

I found out that the rain is not available in the database and saw some discussions about it.
What I now did was adding some values to the Interceptor Stanza in the weewx.conf:

[Interceptor]

    driver = user.interceptor

    device_type = ecowitt-client

    port = 8000

    [[sensor_map_extensions]]

        rain = drain_piezo

        rainRate = rrain_piezo

        supplyVoltage = wh90batt

        referenceVoltage = ws90cap_volt

But it shows me no rain in my skins. Currently it is not raining, but there was rain this morning. Is the data only filling the actuall rain into the database or also the data from this morning? If not from this morning, how can I insert that data afterwards ?

in the log it shows me the following entries:

Jun  4 14:46:10 weewx weewxd[1727]: INFO user.interceptor: unrecognized parameter runtime=80319
Jun  4 14:46:10 weewx weewxd[1727]: INFO user.interceptor: unrecognized parameter heap=94012

Jun  4 14:46:10 weewx weewxd[1727]: INFO user.interceptor: unrecognized parameter wh90batt=3.14
Jun  4 14:46:10 weewx weewxd[1727]: INFO user.interceptor: unrecognized parameter interval=16

so rain is showing some values here...

Also after some rain now, nothing shows up at rain. There is also nothing written down in the database…

Anyone that can help?

There is a fork of the GW1000 driver here which was synced with Gary's main branch just before he went 'off air'. It is a better bet than the Interceptor driver. I have GW1000, GW2000 and GW3000 devices and they all wrk perfectly.

In case you switch to the nice gw1000 driver via Ian's link, here's my old config for my WS85 which is similar to your WS90, as well as the incantation to test the driver interactively.  Be a little forewarned this was quite a while ago and I decommissioned the ecowitt haptic sensor because it wasn't too accurate, but the weewx setup did work as I recall.  Your paths vs. the example --test-driver below will vary if you did a dpkg installation.

Thanks guys, I switched now to GW1000 Driver. Test driver also seems to be looking quite good.

Is there any chance to add the rain data in the database? I had 15.3mm rain yesterday, which is also the week, month and year totatl, since I started the weather station on tuesday night.

[Markus Lösch]

oh and another question I forgot to ask...

I set the customizued server to enabled for the Interceptor Driver. Now, I assume, for the GW1000 driver it is not needed anymore, right ?

[Rainer Lang]

if you take the time to read  the Ecowitt WiKi

https://meshka.eu/Ecowitt/dokuwiki/doku.php?id=start#data_flow_between_sensors_consoles_application_software_and_internet_weather_services
to understand how Ecowitt (clone) consoles communicate

and also the weewx chapter in the Ecowitt WiKi

https://meshka.eu/Ecowitt/dokuwiki/doku.php?id=dataloggers#weewx
you will get a better understanding of what you are doing and what you have to do
also where (and how) to store your rain data
there are several ways/options how to do this

in short
1. you don't need the customized server when using the local Ecowitt API driver (a.k.a. GW1000 driver)
2. there is also an extended version of the Interceptor driver which even provides data the local Ecowitt API driver does not (and cannot) provide.
The "bare-metal" version of the Interceptor driver as available in Matthews repository is hopeless with a modern Ecowitt station and needs quite a few adaptations
which a German developer has thankfully made and it works perfectly.
3. there are several advantages to using the GW1000 drivers, especially to catch correct data as the customized server posting is (downward) limited to 8 seconds,
whereas the local Ecowitt API driver can theoretically poll data on a one-second basis if this is wanted and considered to provide added value.

Thanks Rainer, I disabled now the customized server also. At least, it seems to run pretty good now with the GW1000 Driver, I also had some entries in the database, so I wait for the next rain and see if it is working properly.

I will have a look at it, it is quite huge and a lot to read, but when I do have some time in the evening, I will do it ;)


But if you can maybe answer me my question, if it is possible to import the missing rain data of yesterday, and if there is any extension needed, that would be appreciated :-)

[Rainer Lang]

if it's only rain data from yesterday, you can look them up in your dashboard at ecowitt.net - assuming you have your console post there
And then I would install sqlitebrowser (unless it's already part of your Linux installation) and edit and save the data directly in the database
(make a safety copy of the database before 😉)

try

sudo sqlitebrowser /var/lib/weewx/weewx.sdb   

or whatever is your weewx database location
(you have to open it with root rights, otherwise you will not be able to change fields)

if it's not included, install it first

sudo apt install sqlitebrowser  (assuming apt is your package manager)

find your time (it's EPOCH format - maybe ww.epochconverter.com would be helpful) - locate the rain and rainrate fields and change then accordingly - hint: for changed dsts to be accepted, you have to click with the mouse into another field

Make sure that you save your changes between weewx dabatase activities - let's between minute 2 and 4 of your (assumed) 5 minute weewx archiving cycle
e.g. weewx archives at xx:00, xx:05, xx:10 etc. - you save your sqlite browser changes at xx:02 - xx:04 etc. - not to interfere with weewx
or
once you have done the changes, shutdown weewx after the archiving, save your sqlitebrowser changes and restart weewx

you will have to rebuild the database indexes for yesterday for the data to become visible in your skin (--> weectl database)

[Markus Lösch]

thanks for that explanation, I currently tried it with the sqlitebrowser, but when I want to open the database, I receive the following error:

sudo sqlitebrowser /var/lib/weewx/weewx.sdb
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted


I copied the database on my windows machine and opened it with "DB Browser for SQLite" and checked the fields rain and rainRate in the table "archive"




here I can insert the values manually according to the exported csv.

I think it takes me more then one intervall (5 Minutes) to insert all the values.
I would think the best thing is to stop weewx after the latest intervall, insert all the values, copy the file back, start weewx again.

after that I run

  weectl database rebuild-daily --date=2025-06-04 that the database is rebuild for yesterday.

would that be the right thing to do?

[Markus Lösch]

I tried it and was not succesful, I mean I got it right with the rainRate, but not with the rain.
it showed me much higher values as it was yesterday. 

I had 15.3mm total yesterday, here it shows me a total of 181,6mm.

I used the hourly column of the excel, since it has the lowest values...

I used inch values for the database, since it is set to US in the weewx.conf

[Markus Lösch]

I have now sorted it, needed to calculate the differences in the rain for each 5 min intervall, now I have the right total sum

thanks anyways for all your help, really appreciated
