tested on 65OLED707 :
enable remote ADB in pilips android TV
search for "How to Set Up and Use ADB Wirelessly With Android"
(I used this app: com.waxrain.telnetd)
connect adb in my PC
adb connect TV_IP:5555
START PAIRING ACTIVITY:
adb shell am start -n com.android.tv.settings/.accessories.AddAccessoryActivity
press the pairing button on the remote until the LED flashes (2-4 seconds)
Two devices are detected, an audio headset and a remote with a cross. I selected the controller
and works!!!
tip: do not choose the cheapest remote control... mine does not have a quality microphone, a usb conference microphone inserted into the TV worked better for me
On my Philips with android it is (translated to English menu) All settings-> wireless connections->remote control.( same sub menu where Wifi and Bluetooth settings are).
