First, I am a complete beginner at Home Assistant.
I have a value from a sensor which is not good to read. E.g.: 0,562
So I want to multiply it with 1000 and want to exclude the decimal places. Rounding is not necesarry but could be possible too.
So the example from above should be shown as 562.
My target is to show it on the main overview page and also as a graph/chart.
So my trys and thinkings are about the following, but I dont know if this could be possible:
Create a helper which can added to the overview page
A script in a automation, triggerd from the device (newest value) does the calculation and saving it to the helper.
So is this possible? Or how could it be possible.
Important hint: I do not have the supervisor and addon funktion (just core installation) so edit the YAML files with the official file manager addon would not be possible?
Well as I said I am a complete beginner. Where do I paste the code?
As the manual describes it is all about the configuration.yaml. But I can’t use it with core installation, can’t I?
The integration is Zwave. How could I find out if it does it?
