Understood. Will it be enough to just purchase the RM4 mini? I found it on Amazon (https://www.amazon.com/Broadlink-RM4-Universal-Control-Compatible/dp/B07ZSF46BX?th=1) or do I need more than that?
I use these on some cheap projectors that I have that will play files. You can program it to power on, wait a few seconds, then navigate to the files you want to play.
