This would be a huge easy win for working with the inexpensive Logitech Hubs, they can be found at times for $58 at Walmart   

Would absolutely love, love, love to have this added!!!

When you control your AV equipment with Harmony Hub, you should "throw away" all other remotes while the system maintains state. Controlling something via the Harmony remote and than another, disturbs the state and thus makes things impossible to use.

While I have a Harmony Hub, the Smart Remote (which is shipped next week)  should/can not control equipment which is controlled by the Harmony. Please support this device, it also opens up a lot of other possibilities.

Alternatively make it possible to write services where the Smart Remote can connect to, controlling my Harmony or other stuff. I have a FHEM system controlling my blinds, heating etc, opening this to Smart Remote brings that which I want.

If my echo can control my harmony via a akilll, there’s obviously an API you can use - perhaps you need to team with Logitech but should be doable
