Possibility of controlling with 2 relays

[Turbovix]

you can use 433M sender's pin and IR receiver's pin (remove IR receiver tube if not need to use it).

I see that I have no way out, as I need pin 19 to receive commands from the handheld transmitter.

Therefore, even using the IR pin, I am still missing one.
I'll have to buy another board, I'll look at the KC868-A6 to see if it meets my needs.

Thanks for the help.

I promise it's the last question.
Would it be possible to use the (Beep) pin, capturing before the voltage divider?

I just did a test here, and it is possible to use pin 18 without any problems.
For now I can solve my problem.
However, I will buy the KC868-A6 or A8, as I may need more outputs in the future.
Thank you again.
