Catch a click on a lumi.switch about miio HOT 3 CLOSED

Thanks! I'll update the README to be a bit clearer about subdevices not having tokens.

Thanks for the report.

The proper way to do this via miio is either to connect to the gateway via miio.device or use discovery:

A call to miio.devices() would return a browser that should find your gateway and any devices connected to it. You can filter the results and add listeners to anything that is of type controller to listen for actions:

const devices = miio.devices({
  filter: reg => reg.type == 'gateway' || reg.type == 'controller'
});

devices.on('available', reg => {
  const device = reg.device;
  if(! device) {
    console.log(reg.id, 'could not be connected to');
    return;
  }

  console.log('Connected to', device);
  if(device.type === 'controller') {
     // This is a controller such as a switch, cube or wall mounted switch
     device.on('action', action => console.log(action.id));
  }
});

That should get you started! To help with debugging its also a good idea to run miio --discover to make sure that the library can see your gateway and the devices connected to it.

This snippet works :)
But in my case, I was using the snippet examples on the main readme and it was not working because of this part :

 if (!reg.token) {
        console.log(reg.id, 'hides its token');
        return;
    }

Because all subdevices were hidding their tokens, it was always exiting before listening for action event...

Why exiting if no token ? Because finnaly even with no token, the library manage to detect devices events

Using a simpler snippet example like this would have been an easier way to start with the miio library :

const devices = miio.devices()
devices.on('available', reg => {
    const device = reg.device
    if (!device) {
        console.log(reg.id, 'could not be connected to')
        return
    }
    console.log('Connected to', device.type)
    device.on('propertyChanged', e => console.log(device.type + ' : property "' + e.property + '" changed from ' + e.oldValue + ' to ' + e.value))
    device.on('action', action => console.log(device.type + ' : action detected "' + action.id + '"'))
})

I'm not here to promote the previous library I mentioned before or any other library, it's just a feedback from a user that tryed to detect events on his chinese low cost home domotic kit 😄 and this token part was not easy to understand.

Even the miio --discover that I've tried was not clear in my mind how it could helped me, here is the output :
