Hi Sean,
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.
Adding
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.
