I had a Logitech Harmony 525 Universal Remote Control, and when I first purchased it I was fairly keen to control various things with it.
There were quite a few annoying things about it, such as the really annoying illumination where it lit up very brightly when you went near it, or picked it up, or touched a button. It stayed lit up for ages, and really ate batteries, 4off AAA which might have lasted for a couple of months of light duties if you were lucky, and probably about a week with rechargeable batteries.
For a so called smart programmable remote control, you would have thought that there would be an option available to turn off the annoying and unnecessary illumination, but no.
At the time, I had the following devices connected to my TV
Humax PVRs 6 off
Topfield PVRs 2 off
Panasonic DVD/HDD/VHS combo
PlayStation PS3
Denon AV Receiver
There may well have been other items connected, that I have simply forgotten about.
I now only have the Panasonic DVD/HDD/VHS combo remaining, all of the other items have been disposed of.
The main reason for purchasing the Logitech Harmony 525 was to control the second Topfield PVR using the code set from a different Topfield model, and thus allowing them both to be independently controlled in the same room.
Fortunately, the Humax PVRs had an undocumented feature where the remote codes could be changed from a choice of six available sets, and hence the six Humax PVRs.
I had a small table next to my chair, where I laid out the twelve remote controls for the above items, including five identical Humax remote controls, numbered 1 - 5, this made for very simple operation in every day use.
