Oh my so many ways here are a few:
1) a long wire
2) IR transmitter/receiver
3) conncect two esp32's to a common wifi router half way between the two points now only need to transmit/receive 1/2 the distance
4) a small vehicle that carrys the message
5) a whistle sound and listen for it at the other end
6) a long string and a motor or servo to pull it and a switch on the other end
7) a trained pet to carry the message
