Yes that sounds familliar, I think I have the same setting. My one stays on for 15min. I think you may be missing a pull up/down resistor when connecting the RG11 to the arduino...
What you could do as an experiment is get it working with a basic switch/button instead of the RG11, so a microswitch or the like. Then swap in the RG11.
See here for a good example of using the resistor in an on/off button circut https://www.arduino.cc/en/Tutorial/Button
from cloud-rain-monitor.
update:
I've disconnected the relay ouput from the RG11 sensor, and connected pin 8 from the Arduino directly to the ground.
Now it shows a constant "false" in minicom:
{"rain":false,"sky":25.63,"ambient":29.01}??q
{"rain":false,"sky":25.67,"ambient":28.99}??q
{"rain":false,"sky":25.79,"ambient":28.97}??q
{"rain":false,"sky":25.87,"ambient":28.99}??q
{"rain":false,"sky":25.87,"ambient":28.97}??q
Am I understanding this correctly that when the pin 8 and ground are making a circuit it's reporting as no rain, but when the circuit is open it reports as rainy ?

What are your RG11 switches set to please?

Good question, I cant remember at all. I remember it detects a single drop and then closes the circuit do you have a link or any info to the available settings and I'll see if I can remember

I have it set to Mode 1 it's raining with the extra 15min.
What I've noticed for example, if you touch the sensor to simulate rain, your code will pick up the rain but shortly will revert back to no rain, despite the relay be active for 15 min.

ah, in the code it says:
_* Wiring:
- Rain sensor:
-
Relay is attached to pin 8 and acts as a simple on off switch_
I wasn't aware it needed a pull down resistor. I'll have to install it when I'm back this following Christmas holidays as there are no shops selling electronic components where I am now.

My bad, sorry about that. Actually you will probably randomly get rain/no-rain readings now so
from cloud-rain-monitor.
That's correct, I had rain/no-rain going round and round :)....
Now that we know it needs a resistor, I'll close this issue.
thanks for the help on this one.
