Please disregard my previous post, I recreated the esp-weather-station.php file, and all is working now.

Thanks for this tutorial. I’ve implemented my own Raspberry Pi server and have everything “mostly” working except for one problem.
I’ve verified that my ES32 is populating the table as expected. If I use the esp-weather-station.php source as is, I receive a 500 (Internal Server Error) in the console when I attempt to open the page.

If I comment out the following section, the page displays with no problem:

if (isset($_GET["readingsCount"])){ $data = $_GET["readingsCount"]; $data = trim($data); $data = stripslashes($data); $data = htmlspecialchars($data); $readings_count = $_GET["readingsCount"]; } // default readings count set to 20 else { $readings_count = 20; }

I added a new line below this to manually set the readings_count variable to 20. The page display now looks normal except for being fixed at the latest 20 readings.

Any ideas?

Hi.
Unfortunately, at the moment, we don’t have any tutorials for ethernet module with the ESP32.

Afternoon,
Thanks for a great project with such a detailed description…
I’ve added a time stamp to the messages for my own information.
However, how can you move this from WiFi to Ethernet…..
I’ve spent “hours” trying to get it to work using a W5500 ethernet module which I can get an IP address, ping in and out but not get the time..
Any help guidance would be appreciated.

I get:
esp-sha: Failed to allocate buf memory
in ssl_client.c
probably due to the
WiFiClientSecure *client = new WiFiClientSecure;
run every loop without cleaning up with delete.

Hello and thank you for the great tutorial.
I have an issue with ESP32 causing a crash/reboot. It seems to be a memory leak eating heap in Secure Client block. Adding a delete client; after https.end(); fixed the problem.

I am using Arduino hardware package/library ESP32 – version 3.0.7.

Hello,
I had this project up and running for a couple of years but started to run into various problems with hosting companies and decided to take the project local using WAMP and MySQL installed and configured on a desktop computer over my home wifi network. I am using your updated files. I continue to receive http response error code -1 with no data being posted to the table. Can you suggest trouble shooting steps? Thanks!

In reply to Ken. It happens to me too. Did you find the solution?
