What makes you conclude that? Because it should work.

I couldn’t get it to work and read in a few topics that it’'s available currently

this.registerCapabilityListener([‘onoff.1’, ‘onoff.2’],  
this.onCapabilityOnoff.bind(this));

am i initializing correctly

Make sure they are defined in `app.json`.

Also, `registerCapabilityListener` is meant for only one capability; if you want to listen on multiple capabilities (even if they have the same “base”), use [`registerMultipleCapabilityListener`](https://developer.athom.com/docs/apps/Device.html#registerMultipleCapabilityListener).

    this.registerMultipleCapabilitycListenerCapabilityListener(

    this.onCapabilityOnoff.bind(this));

```

i tried it like this and i made sure that it’s defined in app.json and in driver.compose.json  
however it doesn’t work

can i register only one onoff capability with multiple channels ?

You have to be more elaborate than just “it doesn’t work”.

What do you mean by “multiple channels”?

it literally doesn’t work no debugging prints executed nothing  
it appears as three onoff switch in the app but none of them execute anything  
below is the onCapabilityonoff function

async onCapabilityOnoff( value, opts ){  
const devicesCache = this.getData();  
const mac = devicesCache.cash[1][“mac”];  
const arpTable = { “ip”: “10.2.100.135”, mac };  
const connection = new ewelink({ devicesCache, arpTable });  
this.log(value);  
if (value == true )  
var tog = ‘on’;  
else  
var tog = ‘off’;  
this.log(value, “tog”, tog);  
var status = await connection.setDevicePowerState(  
devicesCache.cash[0], devicesCache.cash[0][“deviceid”], tog , 3);

```
      this.log("3", status);

}
```

Does it? Can you post a screenshot? I didn’t think that the app supported subcapabilities (it would only show the first `onoff` capability).

I guess it was typo after all, it works fine now  
thanks a lot for your support

this.registerMultipleCapabilityListener(  
[“onoff.1”, “onoff.2”, “onoff.3”],  
this.onCapabilityOnoff.bind(this));
