Device was in my Insteon Hub but didn’t show up in HA with auto discovery. Searching the forum did reveal one old post that suggested it is just like any other switch. I manually added with category 0x02 and sub-category 0x2a (also tried 0x1c) but no lock.
I have the same issue. Any luck since posting?
Thanks.
I just added the 2477x devices as supported devices. I believe they will be available in the 2022.8.0 release which should come out in a week or 2.
