I’m not sure why this isn’t working within harmony itself, there are many different ways that devices can be configured.
But you could certainly set up a daisy chain sequence within SmartThings that would solve this for you.
You would need two separate activities, one that only turns on the power plug and then one that does everything with your actual home theater equipment, but that doesn’t itself turn on the power plug .
Then you would also need a virtual switch.
Now you’re going to set up a daisy chain sequence that looks like this:
- push a button on the remote that starts a harmony activity that does nothing except turn on the virtual switch. You will set up the virtual switch as a virtual timer which will turn itself off again in one minute.
Two) set up a SmartThings sequence so that the virtual switch coming on turns on The TV power plug. You want this plug to be invisible to harmony. It’s just a SmartThings plug which you will turn on and off with smartthings.
Three) when the virtual timer turns itself off, Have SmartThings tell Harmony to turn on the activity that has all of the home theater equipment in it.
The biggest issue with this is that there will be a one minute delay before the home theater comes on. That will work in some households, but not others, but it does mean that you can control the sequence of everything, it’s just that you’re controlling it through SmartThings rather than through harmony. The key is not to tell Harmony about the smart plug at all. Just use the SmartThings/harmony interface to handle sequence
