Hello, I am a new HA user. Is there some sort of glossary or dictionary for the terms HA uses for Insteon? For example, for an 8 Button Keypad Linc, there appears to be two entries for the same button. Button A and Main are used for the same button. What am I not understanding? When naming devices or entities, using the same Keypad Linc example, there is a Name field and a Label Field. What are those two fields used for? What is the difference between them. Thanks!
