Controlling a TV Ceiling Mount with a Smart TV Remote

Projects General Guidance

Dear All,

I have a motorised TV mount :

I also have a smart universal IR RF tv remote:

The short story is i want to use my smart universal remote to tell google "turn the tv on " and the Tv is turned on and the tv mount lower the tv from ceiling.

The issue with using this smart remove is that the remote has a 433Mhz radio transmitter and receiver and the tv mount remote is 2437MHz according to the eBay description. So I cant link the tv mount remote to my smart remote. (it was almost too good to be try when I discovered the smart remote)

I know that someone has done a similar project:
"control-rf-tv-lift-using-ir-remote-using-arduino-build-a-remote-for-the-remote" ( I can't post more than 2 links)

But I don’t want to bust my remove apart and solder in an Arduino as I want to keep it in one piece so I can use if need.

Here is what I want to do.

I want to use an Arduino with a RF receiver and transmitter to firstly to learn what code each button of the remote is and then using a IR receiver I can get my smart remote to transmit an IR code to tell the Arduino to lower or raise the tv.
I have found one of these:
Transceiver nRF24L01+ Module with RP-SMA (WRL-00705)

but I’m not sure if that will be able to receive and transmit on the right frequency or how to use it.
Does anyone have any advice?

In the mean time I'm going to email the eBay seller to ask if I could link multiple remotes to the mount. If yes, then I can buy another one and solder my Arduino to it.

Thanks, Patrik

Probably the easiest. Hacking a copy of the remote that is.

There's no telling that the remote uses the NRF24L01. I know of four different chipsets that use 2,4GHz band signaling, they don't talk to each other.

So doing it the harder IMO way would mean first learning what chipset is being used. Opening up, well one side or the other for a peek.

Then the fun would begin.

I think you are right. The ebay seller is telling me that I can use more than one remote so I will buy another one for £20 and take the pcb out of it and wire it directly to my arduino.

I do have a picture of the chip on the inside. The chip has these numbers on it: BEKEN BK2461 ES00921. If that helps at all?

See picutre attached.

FWIW that appears to be a 2,4GHz UART chip.

Since you are hacking a new remote, it is irrelevant.

There are a few ways to connect a remote control to an Arduino, google is your friend here and focus your search in these fora for plenty of discussion.

Put simply, you'll be using electrical connections to make fake button presses.

You can use transistors or CMOS switches.

Then the code. :expressionless:
