Shock sensor MD-2018R ASK modulation question

Hi all,

I have a couple of these MD-2018R shock sensors:

Currently I have an RF (ESP8266 / SRX882 / STX882) OMG gateway
Those MD-2018R are not detected. Opening one of them I noticed it is written ASK-433.
I don’t know much about ASK modulation and I was wondering whether regular RF with SRX/STX882 would definitely not work.
Would I get more chance building an rtl433 OMG ?

Thanks a lot for your answers.
