Question: what type of batteries? if rechargable is there a cradle or plugin?
Document: Having batteries is great. My kids were constantly leaving my Harmony 880 off the charging cradle and it was always alwost dead.Having the iPhone as an option was nice for us as the whole family has one.Cons:No Backlight (just needd to get used the controls I guess)No &#34;Help&#34; button. So far haven't needed to use it. But that is a great feature.
I have a fairly complicated setup for my AV equipment, with an equipment rack housing a Dish Hopper, a Yamaha receiver, an Apple TV, and a Bluray player. I had previously had a Harmony rechargable remote, and the batteries were no longer lasting long between charges. Once I figured out that I needed to install software on my Mac to setup the hub, everything went pretty smoothly.
The batteries are a standard over-the-counter type that can be bought anywhere for a dollar or less. * Despite the fact that I have a large TV Stand with 3 black glass shelves that is full of various input sources (Apple TV, Roku, Blu-Ray, Satelite, etc), the IR hub is powerful enough to control everything from the center-left shelf, except for one item on that same shelf that is separated by a large Center Channel speaker.
That is insane.Annoyance 2 : Watch battery.Really! I get that a watch battery lets you make the device thin, but I have a drawer full of rechargeable AAA batteries. When this battery dies, I have to shlep down to the store and buy an expensive non-rechargable battery. I would gladly accept a remote control that is half an inch thicker.Despite these annoyances, once it is setup, it works like a charm.
If backlighting risks draining the replaceable watch battery then a rechargable battery would be an option. Personally I like the watch battery because the Lithium batteries in the Harmony One would swell after time and fail. I would much rather pop in a watch battery and be done with it.If you are looking for a simple installation and a low cost solution stop playing around and order this device. I promise you that you will not be sorry.
This condition could only be remedied by removing the battery and replacing it. The 900 always had to sit in its recharging cradle. Since my coffee table is nowhere near an electrical outlet, this meant always having to walk over to the TV to get the remote. The Smart control runs on its own battery.
The remote includes virtually no printed documentation, and Logitech's support website is a complete mess, full of unhelpfully simplistic articles and videos (as well as ridiculous browser and plugin requirements!) and lacking any good explanations of how to configure the device for many very simple scenarios and typical problems.
There is a Silverlight plugin that is used in one setup method (who uses Silverlight??) which made it interesting on a Mac. One browser worked and the other two didn't (can't remember which). It was also weird that my other MyHarmony remote didn't show up in the newer Harmony setup. It would have been awesome to be able to have my Harmony One setup automatically transfer to my new remote.
Very cool. The unit controls my tv, my receiver, and my windows home theater PC. It's very easy to setup. Hint: perform your setup using the browser plugin on your computer. There are far more options for controlling power settings, timings, and other options which do not appear using the app. The android app is a little clunky. Maybe the ios one is slightly better?
The remote unit is thin and lightweight, the lightest and least button heavy of any universal remote I've seen. The remote does not have a rechargeable battery mechanism so you don't have to remember to put it back on the charging cradle like the Harmony One. I was also able to operate the system using the app on my Android tablet, which worked well for us.
Answer: It comes with one CR2032 coin cell battery. This website has more info https://logitech-en-emea.custhelp.com/app/answers/detail/a_id/42230/~/harmony-smart-control-remote-battery-life-and-replacement
