I'm so sorry to burden you experts in this field, as I'm sure you figured out I am not efficient or expert. I only know one language English. I can't express enough how much I do appreciated all help and suggestions here. I have downloaded x10 raspian buster to pc again downloaded to image disc file to SD using etcher, setup localization SSID expanded file system and it is going through its update now. Are you guys suggesting I backup to another sd before I configure the modules I use and before I set up my scheduler?
