Extract value with quote''

Questions & Help
1

Hello,

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

This script:

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

return true

Return this:

  }
}

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:

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);

Return:
`❌ Script Error
:warning: testSpa.js:2
log (spa.capabilitiesObj.[‘measure_temperature.DS18B20-1’].value);
^

SyntaxError: Unexpected token ‘[’

Sorry, copy and paste error I think, try without the . before the [

Yes! Thank you! :slightly_smiling_face:
