Hello,
very new to HA and I was hoping someone can help me by pointing to a way to this:
My TV (Sceptre U500CV) remote does not have a discreat HDMI 1 (or 2 or 3) button… but the TV uses Sony codes and Ihave a bunch of codes I want to try… (since I do not have a SONY remote, I cannot teach RM MINI 3).
Is there a way I can teach the RM-MINI 3 a code from HA that I input (as opposed to learn from the RM MINI?
