Hi my idea is show in the dashboard temperature outside (open weather) and inside from sensor, i do not found how to send the temperature 
What is working ? i can see the weather data in serial monitor, and I´ve mills() send from ESP to the dashboard.
But i try several ways to send the openweather data to dasboard and always get an error.
