There is a Linux project my fanbois brother suggested a while back ...
I had a shufty ages ago when I "acquired" a USB IR receiver for use with
a Powerpoint PC.
The problem was the remote (which I finally replaced via a man+dog
operation on eBay) was a never-heard-of-before-or-since brand, and the
codes weren't shared by other remotes and I couldn't get LIRC to read the

It is possible but you have to train the unusual protocols in and live
with the buttons not saying the same on them as on the real controller.
Quite a few generic ones will do a vast range of kit a few have a learn
a new controller mode if you can be bothered setting it up.
I never found one that would work the VH Karaoke machine. Fortunately a
few years later it turned up in the bottom of a box of bunting.
It can be very confusing though as many modern Toshiba and Panasonic
sets are badged and no longer respond to Toshiba/Panasonic controllers!
Way back around 2001, we had an HP Ipaq with a GPS receiver sleeve (it
cost around a £900 IIRC. One of the apps on it was a remote control
(Nevo I think), which could be set up for whatever you needed.
I have often thought that it is a great pity that mobile phones dropped
the IR transmitter. There is so much that you could use that for.
Yes. I've seen them, but the USB ones don't seem a good idea. They'd end
up on the wrong end of most phones, stick out enough to get damaged or
cause damage to the phone if left in and will add wear to the socket as
they have to be taken out for charging the phone each day - my son has
already had two phones fail from the extra stress of using them on the
bus while connected via a cable to a powerbank.
Bluetooth gets around that, but would require them dotted all over the
place (we'd need a eight dotted around for various TVs, hi-fi, sound
systems, etc. and, in two cases, probably two in the same room. Not all
would be easy to position where they would work well. Anyway, I'm not
sure how well a phone would cope with 8 different bluetooth IR devices,
all in range at the same time - and if it can, how you'd avoid operating
two devices of the same make and model in different rooms at the same
time? Can more than one phone be connected to the same bluetooth device
at the same time, as there'd be five phones in the house at once?
The point and shoot ability of a phone with IR at the right end would be
so much simpler. I presume they took them out to save space, as I would
have thought them something that so many people would find useful these
The better option is probably wi-fi to IR devices. Much more likely to
accept multiple phones at once and to be able to direct control for a
specific device to only that IR blaster. I don't know whether that is
the case or not, so I'll have to look into it.

The Harmony 650 does 5 devices I think. The 665 does 10.
The 650 is discontinued, but widely available. The 665 costs little more.
At the more expensive end is the Harmony Elite which I think uses your
wifi and comes with a hub for siting near your devices and can connect
I have the older 600 and it is beginning to give up now, but was used
for many years and does still work.
It has become less important for me, because CEC has taken over the job
of turning the TV on and off with the boxes and selecting the right
input and now we only normally use one box plus the Blue-ray player, so
two remotes is no real hardship. The 600 has been relegated to operating
the hi-fi separates for some time.
They don't mention it now (in fact I don't know if they even offer it
now), but there is also a stand-alone set up program. I've not used it
for some time now, but at the time, there were some things that it did
that you could not do on the website and vice-versa. They have probably
improved the website by now though.
There's nothing "clever" about the IR signals that control your TV (or
All they are are a binary code transmitted at some specific frequency or
combination of frequencies
Any IR transmitter is going to be capable of morphing the signals required
by any TV (etc)
the hard part here is in creating a user friendly way for the remote to
learn what the codes are (and assigning that code to a specific button)
and that's where these products fail.
