Hello,

I want to get a sensor value but i have problem with quote.

This script:

```auto
const spa = await Homey.devices.getDevice({id: '2aba115d-86be-493b-98cf-8dfb1c8185de'});
log (spa.capabilitiesObj);

return true

```

Return this:

```auto

    },
    id: 'measure_signal_strength',
    options: {},
    values: undefined
  }
}

```

I want to get value of `'measure_temperature.DS18B20-1'` but i dont know how do that because there are quotes.

For `measure_signal_strength` i can do this:

```auto
log (spa.capabilitiesObj.measure_signal_strength.value);

```

How can i do for `'measure_temperature.DS18B20-1'`?

Thanks

Try:

`log (spa.capabilitiesObj.['measure_temperature.DS18B20-1'].value);`
