Learn RF for blinds 
Should I leave the config file as this to let the home app learn automatically RF?
          "data":{
            "open":"2600500000012...",
            "close":"2600500000012...",
            "stop":"2600500000012..."

Or should I set it like this?

          "data":{
            "open":"",
            "close":"",
            "stop":""
