Sorry in advance for the stupid question but I didn’t find a valid answer.
I’ve a configuration.yaml file that contains all the modbus integration sensor information to read my EPEVER solar controller data.
There are recurrent parameters like:
scan_interval: 5sec
I would like to set this value only once using a variable or something to be able to set all the parameters changing one value only.
Thanks for the support.
Which is the best way to solve?
