Thank you both for your answer! I prefer 3FG solution, not that the Pronto Idea is bad!

3FG, will I need any special knowledge to see the pronto hex format through the Irscrutinizer?

Also can Pronto or Irscrutinizer show codes of aircondition remotes, and virtually any remote, in Pronto HEX format?

*Ernie, sorry for not beeing more specific on the models that I need their Pronto Hex format of remote functions. One equipment I need to control is an Audio Analogue Puccine SE amplifier, the second is a Sharkoon Acoustics 5.1 speaker package, and the 3rd is a Toyotomi Akira aircondition... Also, an HDMI splitter (4x2) and other useless stuff! :-)

It would be good if I could buy for example a galaxy note 8 and by using the IRremote app to control all them....
