Great Work! Only problem is the time in the google spreadsheet is incorrect. How can I get it right to UTC Offset: UTC +8? thanks SOLVED: I changed the timezone to "Asia/Jakarta" from "CST"
Has anyone recently (5.26.2022) had any success with this tutorial? I still have made no progress with getting the code to show up on google sheets. Not sure if this has to do with the recent update to google sheets as Ganesh G also recently mentioned. The ESP code works great and attempts to communicate with the google sheet but no data is transferred. Other than this current challenge, this tutorial was very well done and helpful. Any assistance or suggestions in resolving this challenge would be greatly appreciated.
Hi! So this code seems to work perfectly for most of the times. But sometimes I notice that ESP32 is unable to send request to the web. Like by debugging from serial output I figured that it is successfully creating query link, but apparently it fails to put that request into web. What can be wrong here??
Looking at the output of the program on the monitor, I see that the first four lines of the certificate are missing. Maybe because not enough memory when declaring root_ca? What do you think and what could be the solution? Thanks
Every time I publish to my sheet, it takes about 7 or 8 seconds to appear and the response I get takes the same and it is 302 (shouldnt it be 200?) How can I make the publishing take shorter time? id love to publish every 500ms or 1000ms. thanks
Hi, it wont be faster than ~ 5seconds, yep 302 is ok for google sheets, you may send a batch or records to speed it up, 60-120 records in one request every minute
Hi, this is a very good video. The codes work on DOIT ESP32 DEVKIT v1, I also managed to connect DHT22 with temperature readings. However, I have a problem with the time zone. It keeps showing UTC time instead of the time zone entered in the code. Do you have any suggestions?
@ yonan prihhapso yes, the same for me, but it used to work, now your time zone should look like 'America/New_York' the list is here developers.google.com/adwords/api/docs/appendix/codes-formats#timezone-ids Thank you!
Great and easy to follow tutorial but I too am having troubles with getting the data to show up on google sheets and am not sure if it has to do with new update. I also noticed that there has been a change in google sheets and was able to find App script under the extensions tab. The tutorial from there seemed to work well with deploying/authorizing the web app and then loading the Arduino code. Serial monitor displays the data attempting to send but it is not received in the google sheet. Any help on this would be greatly appreciated. - 5.22.22
It returns -1 httpCode for me. I did everything like you showed. I don't know where i am going wrong. It returns OK if i make the same request from the browser.
this is a connection error try requestcatcher.com get an url there, for example if you get aqib.requestcatcher.com add a line url="aqib.requestcatcher.com"; right after String url=".... in sendData function if no request appears in the catcher something wrong with your internet
@@anyboards8006 Thanks for the quick reply. No requests appear in the catcher. I even tried with a different internet connection. Still nothing. If I try the original code, it does not print response (line 102) in the serial monitor. It only prints response if i write the "Serial.println(": done "+httpCode);" above "http.end()"
