1) The distance to control infrared device is too small - less than 1 meter. I suspect one of 2 cases :
a) the infrared transmitter frequency 38KHz is not the best choice for any device. Although I tested 36KHz, 38KHz, 40KHz - the best results/distance I noticed for 38KHz
b) the infrared transmitter is not powerful enough - it is infrared diode with 200 Ohm resistor:
I want to improve IR transmitter by adding transistor amplifier into this device:
If you do not want to solder anything, you may try "4 Directional IR Transmitter" (but I did not notice the amplifier there):
