take a photo of your 433MHz receiver module

see the picture. I still encounter some spurious receive-responses in the logging, but much less tan before.

can you try to remove the BLUE antena from your receiver module?
i think maybe you have other 433M sender device have always sent the signal. such as PIR sensor or other sensor.
