Thank you for taking the time to submit your bug/issue! Please use the points below as a guide when submitting.
-
Device & model you are using (Ex: Pi 2 Model B or Arduino Uno with W5100 ethernet shield)
ESP32-DevKitC -
What dashboard are you using? (Web, iOS, Android)
Web -
Please describe the bug / issue as detailed as possible. Attaching the code and any relevant screenshots would be very helpful!
When I check the data plots from “details and chart”, data other than the last one is not displayed.
Data that was previously displayed will not always be displayed when the latest data is added.
In another topic, it was commented that this symptom can be avoided by using a “custom button” and specifying the display date and time.
However, I tried that and it did not improve the problem.
When I checked the values in “Data”, I could see the data for the period not shown in the plot.
I am running two sensors with the same configuration, and they both have the same symptoms.
I am very troubled because the main purpose of using this product was to check the data in the plot.
I don’t want to lose access to past data, so if possible, please let me know what to do other than resetting.
<Arduino sketch>
/*
This example sketch shows how a value can be sent from the Arduino to the Cayenne Dashboard at specified intervals.
The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. Set the Cayenne authentication info to match the authentication info from the Dashboard.
2. Compile and upload the sketch.
3. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
NOTE:
For this example you'll need SimpleTimer library:
https://github.com/jfturcot/SimpleTimer
