Question: Can you use more then one Smart Phone at a time?
Document: Unless of course you like touch screens. But then of course you could always use a tablet or smart phone so I still have to wonder why spend 3 times as much when this one does everything you need.Overall I have to say for the first time I think I have a home theater remote that works incredibly well, does everything I want and looks very stylish. In the past I always avoided harmony remotes because they were always big and ugly.
I read a review of the Harmony Hub and was intrigued. However, the hub was not available by itself at the time I wanted to purchase, so I settled for paying an extra $30 and getting the Harmony Smart Control, which comes with a real remote control unit in addition to the smartphone app. I am so glad I did. I have yet to use the smart phone app for changing channels or volume because things work so well using the remote.
I had the harmony one remote but after a small child decided to put it in the toilet I needed another one. Being able to use our smart phones when the remote goes missing is great, but pulling up the app can take a lot of time so it's a still a pain. The main issue I keep having is having to pair the PS3 with the hub over and over again. Still haven't figured out why this is happening.
I love harmony remotes! I have a lot of devices hooked up to my TV (up to 9 at a time) and I love being able to only use one remote to control all my devices. I have owned both a Harmony 510 and a Harmony One remote and really liked them both, but I am really enjoying my Smart Control so far! Unlike most harmony remotes they moved away from the having a screen built into the remote with the Smart Control which I really enjoy.
I have been suing universal remotes for years and the Harmony Smart Control is far and away the best one yet. I wanted a simple to use, easy to set up remote that works every time. For $100 I got exactly that. Within minutes I had the remote set up to control 4 devices in my bedroom. The small hub was able to be placed out of the way and controls all 4 devices perfectly every time.
Fantastic remote. Replaces many remotes with one amazing combination, your phone, Hub and simple remote. Initial setup could be tedious for first time use. But once setup, it works fantastic.
This remote has no noticeable delay that I can see. I to bought this for the physical remote and not so  much for the app, but I do have it on my android tablet and phone. I do use the app to turn everything on before heading to the basement so the projector has time to warm-up.Yes, the hub comes with 1 external IR blaster, but I didn't use that one.
Another was the simple remote, I like the idea of being able to use my phone as a remote but not all the time. Mainly for more complex actions and I figured the simple remote might offer me access to most buttons. Turns out however that you can with a little creativity access every command you can think of as ALL of the buttons on the remote are dual command one for a quick click and one that runs with a click and hold..
This is a wonderfully functional system, can't Just call it a remote. Initial activation only workers with newer cell phone which only helps finding the network. (instructions don't elaborate on this) Instructions should say INITIAL set up requires new phone OR use computer to find network. Once the network is located and logged in, any smartphone works with the awesome app. No ridiculous time spent typing in codes for manufacturers 30 different devices and selecting one with partial functionality.
I've owed 4 Harmony remotes. This is the best one! By far easiest to set up than all previous remotes. I love that I can use any smart phone and ipad as my remote. I highly recommend this product!
Answer: We have ours set up on both my phone and my husband's phone, and have had no issues.
