Task
How to get my Netatmo weather station readings into my KNX network using LogicMachine?
Things to prepare in advance
- Buy Netatmo weather station
- Create a private app at http://dev.netatmo.com
- Add the following function in Common Functions or User Library
- Fill in the script with client_id, client_secret, username and password
- Rename object names with your own objects
- Rename module names to match configuration in Netatmo
