RFM69 - 433 Mhz detector

[mikulst1]

Hello,
I would like to ask, if there is a possibility to detect 433 Mhz transmission with RFM69. I have a device that transmittes in 433 Mhz, but I don't know how packet looks like or modulation... just nothing. I just know it is in 433 Mhz.

I need just detection of packet and signal strength. I've read whole datasheet and I am not sure, if RFM69 can do that.

Can someone help me please?
