433 Receiver shielding
My goal was to shield the "approved" receiver from any noise by putting it in an faraday cage ( alufoil box ) together with an TS-33C temp/hum sensor to record raw data because i would like to have this protocol implemented in pilight.

I was not succesful - the USB and data cable picked enough 433 signals from outside the Alubox to make this a failure.

It got even worse when i put the Pi with an powerbank also inside that box and let only the LAN CAT6 cable run out. Grounding the Alushield made no difference and even a 433remote control signal from outside could be recognised correctly inside the box ( so not all false noise )

so what are my conclusions

1 the receiver IS sensitive even without an antenna connected
2 the receiver near the pi is not a good idea because of much noise of the pi
3 a LAN cable can cause the shielding to be penetrated by 433MHz signals

has anybody a concept of a shielded connection between receiver and the pi?
