I tried setting up the manual watering system and found it still watered when it rained.  It would be a great feature if it would stop watering even when manually programmed to stop watering when rain is in the forecast. 

Hi. I am new to this myself and have only had the system for about a month. I currently have only three zones and have set them up for daily morning watering. I have smart zones disabled in each zone. 

Under Preferences / Settings - it has a Weather Conditions area. 

Under Rain I have the Strategy set to Expectation,

The Threshold set to 5mm (I actually think I should reduce this to something like 2 or 3mm)

And 

Seems answers are limited for space ....

Then under Days to Skip I have set Rainy day, Next day

This is the first week that I have managed to get the system to automatically skip watering due to rain on its own. 

I think there is still some fiddling to be done, but it works. In the schedule it will be greyed out and list Smart Zones instead of your watering schedule.
