tanks for your corrections and suggestions!
I will use GPIO n. in the defines and I will correct the HW drawing then I will upload a commit that include also the logging fix.
Regarding the future development
I have started working on the master unit core and in a couple of week I should be able to upload something….
I had a look today and I think it will not be a long work than we can go with new sensors and new algorithms(there is a lot of topics on this subject in this forum).
