Recording Temperature with ESP32 & ThingSpeak
Hi all,
I just finished setting up a temperature measurement system for the input/output of my underfloor heating using an ESP32 and 2 DS18B20 sensors. I send the data every 15 seconds to ThingSpeak, and everything is working fine. However, the issue is that ThingSpeak only displays the data in 15-minute intervals, whereas I would like to record these temperatures and view them over 24 hours, 1 week, or even 1 month. Does anyone know what to do? Is it a configuration issue or should I use another service?

To use ThingSpeak, you must sign in with your existing MathWorks account or create a new one.
Non-commercial users may use ThingSpeak for free. Free accounts offer limits on certain functionality. Commercial users are eligible for a time-limited free evaluation. To get full access to the MATLAB analysis features on ThingSpeak, log in to ThingSpeak using the email address associated with your university or organization.
To send data faster to ThingSpeak or to send more data from more devices, consider the paid license options for commercial, academic, home and student usage.
To achieve more granular time intervals for recording and viewing temperature data, you might want to consider using a different IoT platform that supports the desired time resolutions. ThingsSpeak's default visualization intervals might be limited.
Platforms like Blynk, Ubidots, or even creating a custom solution with a database and a web interface could offer more flexibility in terms of data logging and visualization at different time scales. Explore platforms that allow you to customize data display intervals according to your preferences.
