Relay far from house. Is it secure?


Now a day security of your home is foremost priority. I used xbee sx pro along with aes- 256 encryption , I fixed them far away from my residence. I utilize it as relay in API mode and also in router mode. Just want to make it clear which type of safety or security it will be? If someone reach physically to it , is there possibility of receiving data for them?

Because of this security issue, I am thinking of switching to Raspberry Pi platform i.e. Pi Pico module.


Only if they are able to intercept the data packet before it enters the radios UART or after it is being sent out of the UART on the receiving side.
