ESP32-Problem uploading (dht22&ESP32int.sensors) data to the platform

Post by victor6303 » Sun Feb 03, 2019 10:33 pm

Hello from Spain,

Trying to upload some data from an ESP32 (sensors: dht22 only for temperature&humidity).

Uploading the original example (plus adding dht22 data), I got this

On the platform I can see only 100 (continuosly) for Temperature (!) and that's all. No humidity.


Any idea about what can be wrong?
Thank you in advance!

Hello and welcome :-)
Your url is wrong:
https://asksensors.com/api.asksensors/w ... alue232.60
Here is the right format:
https://asksensors.com/api.asksensors/w ... ule2=32.60
I have just done a test using my browser. It works fine and you should receive data. See the enclosed image.

Please refer to this guide for a detailed description of the AskSensors API format. https://asksensors.com/gettingstarted.html.
You may notice that we recommend to use https://api.asksensors.com/write/.... Instead of https://asksensors.com/api.asksensors/write/....
AskSensors now works with both ;-)

Feel free to ask.
Regards.

Nope, it doesn't show any data (or at least, I can't see it), but thanks for your help!

The code I used was quite similar to the ESP32+DHT11/22 example indicated here: https://asksensors.com/doc/WeatherStations.html#ref2 which shows some differences itself...
Source Code :
// Create a URL for the request
String url = "https://asksensors.com/api.asksensors/write/";
url += apiKeyIn;
url += "?module1=";
url += myTemperature;
url += "&module2=";
url += myHumidity;

Besides, when I compare it to the one published on "Instructables", looks like the URL (to be specified) is not even necessary in their code (?!)

Anyway, I'll try it later and see if I can get those values can be seen on the graphic modules, finally. So, I'll be back! :-)
Regards!

Victor,
You should receive data on Module 1 and Module 2 of the Sensor with the API Key you provided. please double check.
The URL is always necessary.
