I get the impression that UR has dropped the "standalone" IR transceivers as smartphones and tablets have "blasters" and users want to use them.
The App now captures IR in a different format to that used a few years ago...... specifically for the device on which it is running.
I use a "Keene IR anywhere" which was one of the first IR devices that UR catered for along with the "Global Cache"
I can no longer capture in the correct format with the recent versions of the app.
I have had to keep Version 3.0.23 on all of my phone devices, capture codes with the phone device (receiving the codes over Ethernet from the "Keene"), email them to myself, and add them to my remotes. They are captured in Pronto format with V3.0.23.
