There was a change to the code a while back made by another developer. You need to use http://XX.XXX.XXX.XXX:8080/sn?sid=1 to get the status of station 1.
You can also do http://XX.XXX.XXX.XXX:8080/sn?sid=1&set_to=1 to turn the station on or http://XX.XXX.XXX.XXX:8080/sn?sid=1&set_to=0 to turn the station off.
