Hi

Im looking for a discrete power on/off command for a mist diffuser.
[Link: esteban.fr]

It uses a small ir remote with a toggle power button.
PCB is a AXD-21B-8P AK393

I managed to find the ir code for the toggle power command:

0157 00aa 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 003f 0016 003f 0016 003f 0016 003f 0016 003f 0016 003f 0016 003f 0016 003f 0016 0015 0016 0015 0016 0015 0016 003f 0016 0015 0016 0015 0016 0015 0016 003f 0016 003f 0016 003f 0016 003f 0016 0015 0016 003f 0016 003f 0016 003f 0016 0015 0016 0015 0016 05fc

repeat data
0157 0054 0016 0e49

frequency 38095

How can i reverse engineer this code in search for a discrete power command ?

Have you looked at the remote's output on an IR detector?
Are you trying to mimic the command from scratch or are you trying to modify a universal remote?

Although many items have a discrete power command that is omitted from the supplied remote, a discrete command may not exist in the unit's command set.

You may need to resort to heroics such as monitoring power draw and issuing a conditional command or using inline power control.
