You are correct that this signal does not presently exist. It would be useful so I plan to added it.
To make it work you would add something like:
from blinker import signal rain_sensed = signal('rain') def signal_rain(): rain_sensed.send()
near the start of helpers.py (just before the function definitions section).
you could then add the signal_rain() function when setting gv.sg[‘rn’]= 1 as you said but when I tested this it sent the signal once per second.
if not gv.sd['rs']: signal_rain()
will only send one signal when rain is detected.
To use the signal you will also need to have something like:
def do_on_rain(name, **kw): print "Rain Sensed" # rain is detected in helpers.py # Put your code here to do whatever you want. rain_sensed = signal('rain') rain_sensed.connect(do_on_rain)
Those last 2 lines will trigger your “do_on_rain()” function when the signal is received.
