Hi.
First want to say that I'm overwhelmed of the information on this site and don't know where to begin. This is why I'm placing this post.

Situation:
I own several Remote controllers to control a: IR Panel, LED ceiling lamp and LED AliExpress lamp (see picture). I thought to simply capture and replay the RF 2.4GHz signals with some to replace the Remote controllers. This to add some RF device to my Raspberry Pi with Home Assistant.

I came across this site: https://www.rflink.nl and bought a Arduino Mega 2560 and a NRF24L01 (see picture). I put it together but sadly I can't get it to work.

Than I came across this site and have hope again.
Questions:

• Should/Could it be possible to record and replay the RF 2.4GHz signals of the remote controls? Some are saying that that there are many protocols etc.
• Can I use my Arduino setup and some software from this site to accomplish this?
