Here’s the PHP Script I wrote for this purpose. I have it ran locally every 5 minutes. I use windows scheduler to run a BAT file that launches the script silently in the background. Maybe this will help you a little to @Dianoga ?
You will need to go to Netatmo and setup a dev account and get a client ID and App Secret. dev.netatmo.com is where you can sign up for that.
then just fill in the bolded stuff below in the first two sections with your APP ID and netatmo username and password. and your station ID and Password for the weather underground station and you’re good to go.
This also does the conversion from Celsius to Fahrenheit and estimates dew point based on humidity and temp.
