Have a look at MQTT. ?The JMRI implementation of this is described and supports turnouts. ?You will need to run a broker, but your PI should be able to run . ? I'd be surprised if there wasn't some MQTT client implementation available for the ESP32 as it's all about IOT and all the connections can be wireless as long as your garden railway is in range of a wifi router.
