i bought toshibat smart tv 32lblabla which lack of functionality of Sleep timer, what i am shocked.
I need this functionality, so I try a lot of android IR remote apps, but didnt find SLeep timer. I tried Toshiba Smart Remote app, and here we go, Sleep timer function was invoked despite it is not officialy supported. THen I want to buid any small device with ESP8266 which will use code 1042 in order to invoke sleep timer.
Simpliest solution will be to find on ebay another IR remote, which has sleep function and works also on my TV, but as I said, i Didnt emulate sleep timer with android apps.
