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.

```auto
` 
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](https://homey.app/a/nl.inversion.esphome/), Homeyduino isn’t really being maintained anymore.
