Had some time to search on Remotecentral, and my conclusion thus far is: Nothing goes unless some manufacturer/modifier offers the hex codes... I have an Interelectro (Austria/Germany) modified TSU7000 with the funny habit of wanted to operate "Rolladen" (blinds) and outside lighting on several day times. And I don't have those appliances! After beeping away it finally stops trying... Removing all instances from App/Settings of the TSU works for one day, then raises this apparantly automatic add-on's nasty head again. (You see it not only in APPS).
Also I found the 433.92 MHz operated power sockets work...sort of. Often they don't work for no apparent reason, when I plug two in from 2 feet from each other, or.... They offered high power sockets for some time, these were not better.
The white RF remotes Conrad in Germany started to offer still are the best (they have been followed by many others in hardware shops etc., but to my knowledge none ever offered usable hex codes.
