hoi mede homey-ers,

hier een code voor een Homeduino thermostaat op een wemos d1 mini + DallasTemp + relayshield. wie weet kan iemand die gebruiken :slight_smile:
groeten,

Allard

  return Homey.returnResult(state);
}

Hello Allard,
Could you show me a picture of the Homey flow that you use to read the temperature?
The Arduino part is clear to me but not the "returnResult"part.
Would appriciate your reply.
Thanks,
