@jbbtex the URL you have is malformed and “result”: 16 means data is missing from the request.
The data that’s missing is the station runtimes because the format is wrong. It should be:
http://myOSipaddress/cr?pw=mypassword&t=[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,300]
The difference is you need the question mark after the command in order to list the variables.
Hope that helps!
