I have a Harmony Hub with Smart remote. In the Harmony app, I want to understand more about the IR Assignments under Remote & Hub. In the first post, it says:
"Go to Settings and choose "Remote and Hub Assignments". From there you can assign a device to the Ultimate or the Hub, and with the Hub you can choose whether the Hub and IR ports are used, or narrow it down to the Hub or a specific port."
In my situation, I have an IR mini-blaster attached to one of the two ports on the Hub. Under "IR Assignments", I configured my Tivo Bolt to use only that port. What exactly does the Hub do to direct the IR commands to the Bolt? Is the Hub actually examining the command and seeing something that identifies it, thus seeing it is destined for the Bolt? And then it sends it out only on that mini-blaster port? (I'm assuming that any device within range of that mini-blaster will still see the command, so placement has to be done properly).
I see the name mdavej in that first post. I posted in a Tivo forum over a year ago about a problem I was having with Tivo Bolt and MCM amp. I decided to ask this more general question here instead. I thought I'd mention him since he helped me, but I'd appreciate help from anyone.
The reason I'm asking this now is that I had assigned the mini-blasters on both the Bolt and the MCM last year to get around my problem. It turns out that only the Bolt actually needed that mini-blaster, and the MCM did not. That discovery made me question exactly how the Hub does this "isolation". (On myharmony site, it says "Changing the mini-blaster port associated with your device can be used to isolate it from other devices that are controlled by your hub, this way it does not receive commands that are destined for other devices").
