I would like to know if the OP has each room and the remote for that room programmed and fully functional. Based on the OP’s post it appears there is some learning to be done in regards to how the RF base stations and remotes work together.

The power control could be done with X10 but that would require procuring used X10 IR-to-X10 interfaces (IR543), phase couplers and noise filters. An alternate to the IR-to-X10 is a IR ISY with a PLM.

IMHO, this project is beyond most DIY’s using IR only devices. As Brad mentioned, this is for URC TC or the soon to be Allonis (here).

My home theater is 100% IR control (MX-980), X10 controls all the lighting and power control for several devices. Have 15 Unit numbers in use, made much easier to use by a X10 computer interface.

Have a lot of X10 at my house. Also use several Z-Wave devices, ZigBee devices, Google Mini’s and Amazon Dot, Cube.

For the home theater:
