Your point about the PI is spot on: a full linux stack means you can get up to "shenanigans" with all sorts of tooling!
A PI with MQTT server and ESP32 as clients is a match made in heaven! For 30 bucks you go from nothing to PI zero, and a hand full (literal) of esp32 devices. Its a fun stack to play with!
