OK, so I can see that your iTach and iFlex are receiving the exact same code, except for the LED 1:1 vs 1:3, and they are both confirming that the code is valid and sent. I wonder if this could be a hardware problem? Are you using the same type of IR blaster or IR emitter on the iTach and the iFlex? On the iTach's web config page, what is the configuration for port 3 set to?
Using iTest, can you try the code on both the iFlex and the iTach, changing 1:1 to 1:3 as necessary? Do you see the same "completeir" message coming back?
Another possibility is the code itself. Do you learn it from a device, or did you find it in an online database? I cut and pasted the code into IrScrutinizer (https://appimage.github.io/IrScrutinizer) which seems to think it is a NEC code for device 4, function 6 and recommends:
instead. This could be a complete red-herring! The iTest version of that code is:
I think I'd start by checking out the hardware and port config. The PI is sending the code and your iTach is responding that it's good, so I don't think the PI is the issue. I'd like to test some more with finding the true "reference signal" for your remote but I'm in the middle of moving house and my IR test gear is packed up in boxes at the moment.
