433 MHz receiver not picking up 433.43 MHz Remote?

[slovniek]

Hello, I wanted to capture RF signals using Arduino with this receiver & transmitter set (AliExpress )
The remote I am trying to sniff signal from is Simu Remote which should operate at frequency 433.42 MHz.

Here is my setup for referrence ^.
I tried using RCSwitch.h and RadioHead libraries. The receiver seemed to be initialized without any issue.
Is there anything I blatantly overlooked or any other equipment I should get to make it work?

Thank you in advance

So the transmitter is on 433.42Mhz and the receiver is on 433.92Mhz ?

Even if the TX and RX were on the same frequecy its entirely possible the TX is using a protocol or modulation that the RX does not use.

There is more to getting seperate TXs and RXs to communicate than just using the same frequency.

Do the bundled transmitter and receiver work together?

That broadband receiver should work even if the frequencies are somewhat different. Since transmission protocols are mostly proprietary, you need a more general method of "sniffing" the signal.
