Continuing the discussion from No values seen in IoT cloud:
Hi, similar problem, values not updating in the web or app dashboard. Everything else works fine. The serial monitor weighs and displays the reading and connections, the SMS function works but the dashboard is showing 0. Have declared the variables globally as suggested, except for the < int upperlimit >, which I think, shouldn't matter. Can someone please help me as to where I am going wrong> Here's the code:
/*
Sketch generated by the Arduino IoT Cloud Thing "Weightscale"
https://create.arduino.cc/cloud/things/f6787cc2-8e93-4138-89e3-e9f23dd83166
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
float mass;
Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.
