Two more possibilities. If your IR port on the base station is dialed down too low maybe try adjusting with a small screwdriver. If that doesn’t help look at the IR repeat length of the command in the macro. If it’s set to 1 bump it to 3. And yes you should alias in macros only. IR commands are only good for line of site but if the remote doesn’t remain pointed it misses. Defeats the idea of the system reliability for sure.
