This is a cool hack!
But what if I want to receive messages from an esp(32) sent to a rasberry?

Inspired by your efforts I have been working on a simple very low power IOT application using uMQTT broker. It is a template for a standalone star network of few battery powered sensors which can be customized easily. There are 2 sketches ProbeSender and ProbeReceiver. ProbeReceiver is using uMQTT broker to connect to outside world and it is up all the time using mains power. All ProbeSendor devices are not directly connected to internet. I have implemented basic 2 way communication between ProbeReceiver and all ProbeSender device on the network. For issuing commands to ProbeSender devices on network I use android app called MQTT Dash. Only requirement for this code to work efficiently (less power consumption) is to have same access point channel as home's main access point across all devices. The link to code is below:
