Report your Weather Station Data to Windy

LZ7AA

Hi guys, I need some help to diagnose an issue I have with POST JSON data of my station. Here is my request:

body: "{"observations":[{"station":0,"temp":23.1}]}"

and i get

body: "ERROR: no params"

Is my JSON format correct? I'm using Node-Red to compile the message and post it.

Good afternoon, colleagues!
I am addressing you with what seems to me a non-standard question.
The situation is as follows - when trying to send data to the site, difficulties arise, what they are connected with, I can’t understand, but I hope for your experience.
I have developed a software and hardware complex for meteorological monitoring based on a microprocessor platform, a sensor unit and a GSM modem for data transmission using GPRS technology.
As a GSM modem, I use the SIM900 module.
The GSM modem is controlled using AT commands.
Sending was tried to be carried out both using the TCP/IP functions, and using the HTTP functions.
That is, by sending a regular GET request in this format:

https://stations.windy.com/pws/update/XXX-API-KEY-XXфX?winddir=n&wind=n"

Where n is the corresponding value of the specified parameter.
According to the latest modem responses, as far as I understand, the error lies in the incorrect reception of the sent request, that is, the server cannot process it - HTTP/1.0 400 Bad Request.
But at the same time in the browser such a request is processed without problems.
I'm sure this system will work because the two sending methods - TCP/IP and HTTP - will do a great job of sending data to Thingspeak.com.
Therefore, I dare to assume that the error may be on the server side, or I am not connecting to it correctly, or for some other reason I cannot get through to the server, or he really does not like my request, or something else.
Usually, when connecting to the server, the command looks like this:

AT+CIPSTART="TCP","api.thingspeak.com","80"

By analogy, I also specify for the site www.windy.com:

AT+CIPSTART="TCP","api.windy.com","80"

But the result is negative, I tried to specify the IP, if I understood correctly:

AT+CIPSTART="TCP","35.201.88.123","80"

But nothing.
I also tried the HTTP method in GET request format:

AT+HTTPPARA="URL","https://stations.windy.com/pws/update/XXX-API-KEY-XXX?winddir=n&wind=n"

But also not effective, I tried many options, there were errors 303, 603 and 400.
Can anyone come across with the organization of such methods of sending? Or understands how to organize it correctly, I will be very grateful.
Below I attach the code of the program, as well as a screenshot of an attempt to send data and responses from the module.

TCP/IP function:
If the URL is "http://api.thingspeak.com/update?api_key=XXX-API-KEY-XXX&field1=n&field2=n&field3=n&field4=n&field5=n&field6=n" and the TCP is "api. thingspeak.com", then everything works.

AT+CPIN?
AT+CSQ
AT+CREG?
AT+CGATT?
AT+CSTT="internet"
AT+CIICR
AT+CIFSR
AT+CIPSTART="TCP","api.windy.com","80"
AT+CIPSEND
https://stations.windy.com/pws/update/XXX-API-KEY-XXX?winddir=n&wind=n

HTTP function:
If the URL is "http://api.thingspeak.com/update?api_key=XXX-API-KEY-XXX&field1=n&field2=n&field3=n&field4=n&field5=n&field6=n" and the IP is "api. thingspeak.com", then everything works.

AT+SAPBR=3,1,"CONTYPE","GPRS"
AT+SAPBR=3,1,"APN","internet"
AT+SAPBR=1,1
AT+SAPBR=2,1
AT+HTTPINIT
AT+HTTPPARA="CID",1
AT+HTTPPARA="URL","https://stations.windy.com/pws/update/XXX-API-KEY-XXX?winddir=n&wind=n" 
AT+HTTPPARA="PROIP","35.201.88.123"
AT+HTTPPARA="PROPORT",80
AT+HTTPACTION=0
AT+HTTPREAD
AT+HTTPTERM

Thanks a lot in advance!

@Vladyslav-Lebediev Hello, what type of weather station do you use? You probably need additional software to be able to send us data.

Vladyslav Lebediev

@Korina Hi! I use a homemade weather station with my software.
I'm trying to send data using the API, but unfortunately your server cannot process my request correctly, or my weather station still cannot connect to your server. It is possible that I am not specifying the correct port when connecting to the server.
May I know your IP, API and possibly port?

Hi, I have 2 weather stations registered in my account. And they work fine. However, I want to add a 3rd one. When I fill in all the fields and click on Save, the station is not added to the list of stations I have. I am redirected to the page listing my stations, but the newly added station is not there. No specific error or success message is shown.

Is there any limitation on the number of stations a user could add, e.g. 2? Or is there something broken in the add station functionality on Windy? Thanks for your replies!

Korina

@mtkrastev Hello, I just tested adding a new station and everything worked as expected. What browser are you using? Also, did you fill out all the fields?

Korina

@Vladyslav-Lebediev Hello, all the necessary details are stated at stations.windy.com. We cannot provide IP. I suggest trying a third party software.

mtkrastev

@Korina Hi, I tried with recent versions of both Firefox and Chrome. I filled in all the fields. Actually, I tried adding a new station at least 5 times, and it never worked. Not really sure what to try next.

Korina

@mtkrastev Could you let me know your station's ID?

mtkrastev

@Korina Hi, the stations IDs are f05140f8 and 1f05140f8.

Korina

@mtkrastev Please try to clear the browser cache. Also, could you post a video showing the error with adding the station?

Vladyslav Lebediev

@Korina Good day.
Unfortunately, I still can't solve my problem, I think that this may be due to the size of the data that I send you to the server, and everything would be fine if I did not have a buffer size limit on my system.
I want to ask if it is possible to change mine API to a shorter one?
I think this might solve the problem.

Korina

@Vladyslav-Lebediev Hello, it is not possible to change the length of the API key.

Vladyslav Lebediev

@Korina I understand, ok, thanks for the reply.
And please tell me, does your server only accept HTTPS requests, or can it still accept HTTP requests?
If I contact your server via an HTTP request, I understand that the server will ignore it? Or can the server still process the HTTP request?
Thanks!

What happens to the data? Is it being used anywhere? I'm sending temperature data but I'm not seeing it on the public map.

Korina

@Hermann-Hafsteinsson Hello, if you are sending us your station's data, then you should see the station on the map. Please double-check your settings.

@Korina
Hello.
Even my station sends the data to Madis, it disappeared from the Windy stations recently. Were there any changes?
Double checked my station data but there was everything ok. It worked OK for quite some time but, then the station just disappeared from Windy (error loading or rendering data message).
Thanks in advance,
Gordana

@Ssnjoff Hello, what is your station ID, please?

noahrasheta

Hello! I have a KestrelMet 6000 Cellular WX station and it’s broadcasting WX data to KestrelNet, Ambient, and Wunderground. Also visible here:
https://www.pwsweather.com/station/pws/UT10CVA

How do I configure it to also send data to Windy? I added a station in Windy but I’m not sure how to send the data over. Does anyone have instructions that can point me in the right direction? Thanks!

Korina

@noahrasheta Hello, you will need additional software. Please check the stations category, there are several programs compatible with Windy.
