I am using Airtel STB and manual pairing of keys are not working. The IR codes are do scanned via HUB but the transmission doesn't work. Also the built in codes( option 2 and 3 ) do work well from mobile app but from remote , these keys do work atleast once when pressed 3 times. Other codes such as of Sony TV do work well from both app and remote. I also tried learning IR codes of Hitachi Window AC, same problem the learnt keys doesn't work!
