Homeyduino mutiiple devices on one ESP32 Board

I have an ESP32 board with 16 ON/OFF outputs, how can I make each of these outputs on a separate buttons in the application.

` 
Homey.begin("SHT40 sensor");
  Homey.setClass("sensor");
  Homey.addCapability("measure_humidity");
  Homey.addCapability("measure_temperature");
  Homey.addCapability("measure_pm25");

Homey.begin("First button ");
  Homey.addCapability("onoff");
Homey.begin("second button ");
  Homey.addCapability("onoff")`

not work.

With apps you can create subcapabilities (like onoff.out1, onoff.out2, etc), but I don’t think Homeyduino supports that.

Perhaps it’s better to look at ESPHome, Homeyduino isn’t really being maintained anymore.
