DirecTv Integration: Cannot turn on nor off the set top box

I originally posted this in the “Configuration” list. In retrospect, this list may be more appropriate.

Link to original post:

Nutshell: Most actions on the integration seems to function, but to turn off or on the set top box, you get a “error doink” on the TV and nothing happens.

What could I be doing wrong?
Thank you in advance.

I know this is old but are these remote (wireless) Genie controllers? If yes, I do not believe you cannot poweron this device, it must be done physically.
