Ecowitt GW3000 user assistance

[gjr80]

Posted in weewx-user to canvass a wider audience.

I'm developing a new Ecowitt driver based on the so called local device HTTP API. This driver will have catchup on startup via either local device history files (for supported devices) or Ecowitt.net (for devices that upload to Ecwoitt.net). Ecowitt's documentation of the local device HTTP API and GW3000 SD card data files is somewhat limited, so I was hoping for some practical help from an Ecowitt GW3000 user (if one exists) who has both tipping (WH40) and haptic (WS85/WS90) rain gauges connected to their GW3000.

What I am after is the header information from the basic sensor CSV file stored on the GW3000 SD card when the GW3000 is connected to both WH40 and WS85/WS90 rain gauges. The basic sensor CSV file name format is YYYYMMX.csv where YYYY is the year, MM is the two digit month number and X is an upper case letter. The basic sensor file can be downloaded via the local device web page or directly in your browser via http://device_ip_address:81/YYYYMMX.csv where device_ip_address is the device IP address and YYYYMMX.csv is the file name as described previously. You can view the availble SD card history files via the device web page or at http://device_ip_address/get_sdmmc_info.

The required data does not contain any sensitive info.

thanks,
Gary

Hi Gary, all I am missing is the GW3000, since I was waiting for your updated driver. How about you? If it's the same situation for you, tell me the shipping address, I'll get you one, as a donation for the project, or, if you decline, I'll buy one for myself, but it'll take a while until I'll arrive.

[gjr80]

I have the GW3000 and WS90 so have the haptic sensor covered, and I can surmise the behaviour with a WH40 only, it is just a case of confirming what happens when both WS90 (or WS85) and WH40 are present. Thanks for the offer, but if I don't get any data responses here I will likely just buy a WH40 and wait for the couple of weeks for delivery.

All going well I hope to have the new driver with backfill ready for user testing sometime in 2nd half of February.

[michael.k...@gmx.at]

I have a spare WH40 for 868MHz, but you are not in Europe, are you? Too bad the GW3000 868MHz is sold out currently, I won't get one before end of February, I assume.

[michael.k...@gmx.at]

I just ordered a GW3000, but it won't ship before March.

[gjr80]

Yes, 433MHz here. I have a WH40 on the way, what's another rain gauge...

Gary

[michael.k...@gmx.at]

My GW3000 is on the way, so it should arrive in a week or so.

[Auchtermuchty Weather]

I have a GW3000 in the UK, Very happy to help if I can.

[Steeple Ian]

Hi Gary,

I have the two types of rain gauge and the GW3000 arrived today.

Attached is a .zip of the 6 CSV files from my SD Card after a few hours running.

Regards,

Ian

...... It does seem however that it only creates columns for the traditional rain gauge and not a piezeo rain gauge, even if priority is set to piezo. I am not sure if this is a bug, an oversight or deliberate. This happens even when the WH40 is disabled. A somewhat disappointing outcome.

[gjr80]

Thanks for your trouble Ian, I hadn't picked up on the piezo bug. I set my GW3000 and WS90 up and let it run for a couple days in December before looking at the csv files. Unfortunately those two days had no rain so didn't think anything of the lack of rain data. Just looked back over the last 7 weeks and no rainfall was recorded in the csv files.

I saw your wxforum post, so I guess we wait. My WH40 is in the mail so I guess chances are it will be here before any firmware update is released.

Gary

[Ian Millard]

No problem Gary.

I see that Gyvate has submitted the request to Ecowitt however I have no sense on how quickly they can respond.

there are a few more things to be considered from the bigger perspective with the GW3000
- some referring to the SD card archiving of also other sensor values (e.g. LDS01, WH57 ...), the file name change etc - all needs to be streamlined - already a few things were sorted with the last firmware upgrade
- some referring to the customized server posting

The WiKi is quite up to date regarding the expected-to-be situation and partly also regarding the "missing feature" situation.
https://meshka.eu/Ecowitt/dokuwiki/doku.php?id=start#gw3000
there is a table with the so-far existing observations in the CSV files corresponding to the header items - and the known missing ones

all this also needs to be synchronized with the WS6210 console, which is the other one having the API accessible SD card option

Some field testing may also be needed

an educated guess would be the end of the month - but they might be faster

Ecowitt has confirmed that the missing piezo data, the WH7 time stamp of the last lightning event and the LDS01 depth will be added to the SD card data with the next firmware for the GW3000 and WS6210.

@Gary: the header text now contains for temperatures a one-character representation of °C and F - this will become two letters/characters "°" and "C" resp. "F"

All the LDS values have already been added to the WiFi firmware of the other consoles (those which have two firmwares) for the Customized Server and for those people using the Interceptor driver it can now also be retrieved
(of course you have to use an extended version of the driver and not the "barebone" version at GitHub - that could get an update with all now existing sensors and values ...)
The world has significantly changed in the past years ... there are user created (tested and working) complete versions available though
Gary's local API driver looks up to date (probably LDS01 to be added)

[steepleian]

Good news indeed. Thank you for your update.

[michael.k...@gmx.at]

In the mean time my GW3000 is installed already in my test environment, so if there is anything I can help with, let me know. I've got no problem even with a still-not-ready, potentially buggy, bleeding edge version of the driver in my test environment.

[Steeple Ian]

I see that the new firmware has arrived. GW3000A_V1.0.1

[Steeple Ian]

Having said that, it is strange that version number has gone backwards and no sign of piezo rain data in the card .csv files after the old files had been deleted.

[michael.k...@gmx.at]

That was a false rollout they did. 
See https://www.wxforum.net/index.php?topic=48216.msg486394#msg486394

[Rainer Lang]

roll-out mistake (almost) in time detected, reported and corrected - the future now hopefully final SD card header layout coming with firmware 1.0.4 is in the WiKi
for the other network readable SD card device, the WS6210 WLAN/4G gateway, additional observations apply - see also WiKi, table of possible headers
https://meshka.eu/Ecowitt/dokuwiki/doku.php?id=start#gw3000-csv
VPD (vapour pressure deficit), unit kPa, an agriculture related observation, will be added to the YYYYXXZ.csv file behind the "Feels Like" observation

[Steeple Ian]

Firmware 1.04 has finally been rolled out for GW3000

[Steeple Ian]

Sorry, that should be 1.0.4
Ian

[Rainer Lang]

the just released firmware final 1.0.4 upgrade for the GW000 should cover all missing entries in the csv files

Gary,

I was just wondering how the development of the new driver is progressing? If you need any help with testing, I am very happy to help.
Ian

[gjr80]

Thank you Ian,

I have a working version running on a system at home. It needs some tidying up plus the backfill via device history files needs a touchup after the v1.0.4 firmware release. The absence of any complete and reliable local device HTTP API documentation is not helping. I am away on holiday in months time and am aiming to have a version suitable for public use by then.

Gary

[Steeple Ian]

Thank you for the update Gary.
