I am sorry, should know this before posting.
I will start with simple sensors such as temperature, humidity and light sensor.
I will most likely use Python to connect sensors with Pi3. I have done in the past some temperature readings but all results were based in the putty.
I also used node-red for user interface but decided that is limited in terms of look etc.
My question is, how can I send live data to dashboards? Is there a need for another programming language? Maybe I don't have to use Python but something else?
If someone could give me keywords/direction I will look and research.
