So after a wile playing and a few basic tutorials. I finally started with my first serious project.
Scope of project: at the end, I like all variables of our home like energy usage, energy production, temperatures in house and temperatures of our heating pump in a dashboard.
First part of my mission is to connect multiple temperature sensors on the complete heating system. We are the owners of a heating pump and I want to learn in detail how the system reacts to tweaking. This is not only for personal use, but I think it will provide me with knowledge that is usefull to use professional ( technical installer).
So part one:
Create a dashboard with sensors to see temperature through several DS1820 sensors. Ive got the necessary items, created a sketch and installed the dashboard. Everything is working fine but one thing:
Make a fixed connection between a DS18B20 sensor and variabel in the dashboard.
I've re-write/used a lot of sketches to work with the factory serial of the sensor, but nothing wil work.
Perhaps someone can take a look and guide me (or deliver the piece of code) to the solution.
Thanks in advance. Your input is appriciated

Sketch generated by the Arduino IoT Cloud Thing "Untitled"

Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
float temp100;
float temp200;
float temp300;
float temp400;
float temp500;
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.
