There isn't a perfect solution when it comes to powering on devices, especially devices without discrete on/off codes. Using tracking variables for power status can get out of sync if a power failure occurs or someone presses the power directly from the device.
The only sure way to track power is to use a processor that has power sensing or video sensing capabilities like the MSC400, MX-1, MRX-10.
- Some CI's tend to turn everything on with the green power button or first activity button press. Easy and reliable! -Some CI's leave devices like cable boxes on 24/7 again to avoid service calls. -Some will turn on each device as required, then turn everything off with the "off button". Requires discrete on/off codes or power sensing. -Some CI's will turn off each device when not in use if they have the proper equipment. Good for the planet!!!!!
I personally turn each device "on" as needed. For example pressing watch cable only turns on the devices associated with that activity. It may be all I want to do that evening why turn everything else on? Then if I switch to the Xbox-360 activity it will power on the X-box 360 leaving the cable box on. I found this to be the best scenario for me because it only has the initial delay the first time the device is powered on. Switching between activities already "on" speeds up the macro. I sometimes switch between say gaming and watching a live sporting event. I also use power sensing in my setup to accomplish this.
When I am finished watching, pressing the "power off button" sends me to a power off page which has different power off options.I do this for two reasons.
1)It avoids shutting everything down by accident and having to wait for my projector, TV or AVR to restart. 2)It also gives me the option to turn off my projector, TV or a complete system shutdown. A system shutdown in my case turns off every device........
I think the correct answer to your question is, "what is best for you and your needs!" There is no right answer!!!!
