Question: Does it switch on and off all the components that are necessary at the moment, say receiver, tv, and cable box?
Document: You have to go to the Logitech website and download software in order for the database to search for and install (via USB wire) your items. I only tried tv, older home theater receiver, and cable box. It does have capabilities to control up to five items (including certain lights, computers, etc.)
Unless you have no computer skills at all, this remote should be a seamless transition of the 3-4 you most likely have on your coffee table as long as you have basic computer skills.I have 5 components ranging from 1 month old Sony TV, to a new style comcast cable box, to a 5 year old receiver.
This thing is great. One button push and I can switch to whatever game system, tv or music settings on tv and AV receiver. Love it.
It's easy to configure, has some multi function buttons, the library has a lot of remote codes (even for old devices).Lacks some configuration for batch commands (like switch on cable box and after a few seconds sending preferred channel), but for the price, it beats expectations.
First, let me say we've only had this remote for two days. If anything changes, I'll come back and update the review. Review:  My husband took it out of the box and got online to enter the information. It was easy to find our components and he had it ready to sync in minutes. Synching, however, was not so easy on the PC. He tried several times and it froze. So we switched over to my Mac and it had no problem.
Like lots of remotes, the common hard buttons  are linked to whatever device you last selected. For me, most of the time that is the cable/dvr box. Now the phone rings and I want to mute, so I click mute. But it mutes the cable box which doesn't mute the tv. You should be able to reprogram some or all the devices to point to one specific devices' button like the TV.
Bought this remote for the bedroom tv because the standard cable box remote has no lighted buttons. This was a wrong choice remote if thats what you wanted. The buttons are tiny and not lit at all except for a little dot (useless). Thought the little lit screen would be perfect but not really because it comes with just a few tv logos, the rest you need to figure out how to download them into your remote (I gave up).
First off, I am a huge fan of Harmony Remotes. I have owned the Logitech Harmony 880 Remote Control - Refurbished,Logitech Harmony One Universal Remote with Color Touch Screen, and theLogitech Harmony 900 Rechargeable Remote with Color Touch Screen.I currently use the 900 in my living room, and got a 650 for my bedroom. It is perfect. I have a tv, cable box, andRoku HD Playerin my bedroom.
Upon opening the box for the Harmony 650, I admit I was a little intimidated with anticipating the setup. It is annoying having 3 different remotes to control things and having one single device to operate things makes perfect sense...if they work. I have had universal remotes before which require you look through a little book of codes printed in 6pt font, to enter your tv, cable box, dvd player, etc. Of course, my (not that obscure) items were never in the book.
I waited to write this review until I had actually used the remote for a while. I have to say that setup was very easy after installing the software. The remote functions very well and I love the fact that you can combine activities such as TV and Cable box buttons together.I did find that I was changing some of the settings and button layouts as I was getting used to the remote and the software. I went with mostly the defaults in the beginning then started to customize based on my experience.
Answer: Yes, you can customize it to turn all on or off. Or you can program one to stay on all the time, such as a SAT/cable receiver so everything starts without delay. Really happy with this product and the programmable devices seem to be endless. I actually have a weird brand SAT cable box from overseas and it found it with no issues. Buy the product and don't buy the higher-end models since this does a lot to begin with.Hope this helps
