After latest update, I can learn the codes for my ceiling ventilator without problems.

Tried the phone restart already?

Some more resesarch and I found out the PS-Button is the "Pause/Break" button on the keyboard. Unfortunately that one is not available in the SofaBaton Keyset for the Bluetooth keyboard. Please add it!

Hmpf, newlines are ignored here...

Found the following list of Keyboard commands on reddit: Esc - back F3 - Dual Shock 4 Options button Prt Sc/SysRq - DS4 Share button Pause/Break - moves you back to inserted disc in the main menu Backspace - back Enter- enter Arrow keys - moving in menus Matrix Blu-ray disc: In-movie controls: Esc - Pause/On-screen display F1 - on-screen display (shows movie progress, type of audio track, etc) F2 - BD pop-up menu F3 - PS4 disc options (pop-up menu, subtitles, audio, etc) Backspace - Pause/On-screen display Up arrow - bring up BD pop-up menu Down arrow - close BD pop-up menu Right/left arrow - moving in menus Enter - enter

Thanks, that solved tho problem for the moment.

In another Post it was stated, that a phone restart helps - I can confirm that. It was for Android, but it's worth a try on iOS as well...

The PS4 cannot be turned on with other devices than the original controllers. Sony does not allow that.

I know, that household equipment is not officially supported - but it should be possible to learn the IR Codes anyhow, or not?

I also just tried to learn the codes for my ceiling fan. It says it learned ok, but triggering the commands does nothing... latest firmware and app installed.
