What I really would like to see is the ability to edit the hex codes manually, as this may require some experimenting... Anyway, the device in question is VU+ Ultimo4K STB, and the functions required are discrete on and off, which are defined as keycodes KEY_KP0 and KEY_KP1. They PROBABLY are the following as hex code. No way to know without ability to test. Seeing the codes from other (existing) remote keys for that device would help also. on: 0000 006D 0012 0012 0008 001D 0008 0065 0008 001D 0008 006A 0008 0031 0008 0031 0008 0022 0008 0050 0008 01EE 0008 001D 0008 004B 0008 001D 0008 001D 0008 003C 0008 0022 0008 001D 0008 0008 001D 0008 0C2C 0008 001D 0008 0065 0008 001D 0008 006A 0008 0031 0008 0031 0008 0022 0008 0050 0008 01EE 0008 001D 0008 0022 0008 0046 0008 001D 0008 003C 0008 0022 0008 001D 0008 001D 0008 0C2C off: 0000 006D 0012 0012 0008 001D 0008 0065 0008 001D 0008 006A 0008 0031 0008 0031 0008 0022 0008 0050 0008 01EE 0008 001D 0008 0050 0008 001D 0008 001D 0008 003C 0008 001D 0008 001D 0008 001D 0008 0C2C 0008 001D 0008 0065 0008 001D 0008 006A 0008 0031 0008 0031 0008 0022 0008 0050 0008 01EE 0008 001D 0008 0027 0008 0046 0008 001D 0008 003C 0008 001D 0008 001D 0008 001D 0008 0C2C
