I also noticed the interval program on the Raspberry Pi does not seem to return status and only allows changing the station status. Looking at the URL defintions in the python code I see this:
'/sn=(d+?Z)', 'get_station', # regular expression, accepts any station number
'/sn(d+?=d(&t=d+?Z)?)', 'set_station', # regular expression, accepts any digits
Either case it seems to require an equal sign from what I see.
