I actually have a MyDatabase set with all codes for Device 229 and 238 for a total of 127 functions in each device based on the protocol. I'm happy to share a small XCF with those codes you could load to get the codeset into your own My Database.

I periodically test all the codes against my ATV and am happy to report that the only codes in the post from Sept 5, 2022 are the ones that are recognized by (LED flash on ATV) ATV.

To date, I've found no uses for the Unknown A-F codes that are in the codeset. ATV recognizes them but they don't perform any specific function AFAIK,.
