i add a slider in cayenne android app but when i want to change its value after 2 sec it sets itself to max slider value . pls help me and sry for bad english.
i am using nodemcu but i think it doesnot matter with problem.
can you share the code, screenshot of your dashboard and if possible a video of the same.
i made a fresh device in cayenne app and i add a slider in it and once i connect it to a CAYENNE_IN func and also i made another one slider and i did not connect it to CAYENNE_IN and both of them worked but also both of them has a problem … when i change its value, after 2 sec its value change to max and i screenshot them as blow
ty
after 2 sec
ty
after 2 sec
this is my code
/*
This example shows how to connect to Cayenne using an ESP32 and send/receive sample data.
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. If you have not already installed the ESP32 Board Package install it using the instructions here: https://github.com/espressif/arduino-esp32/blob/master/README.md#installation-instructions.
2. Select your ESP32 board from the Tools menu.
3. Set the Cayenne authentication info to match the authentication info from the Dashboard.
4. Set the network name and password.
5. Compile and upload the sketch.
6. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.

Thanks for reporting this issue. We are working on it and will let you know once solved ,.
