The last three times weather Canada has sent me an alert that my city of Calgary is under a sever thunderstorm, I find myself waking up to a notification that the sprinkler ran overnight anyway. It’s like: Day 1 – extreme rain until 9pm. Day 2 – It hasn’t rained since midnight so this day is dry and I should run the system.
Seems insane. I’m not using any additional sensors, I have my schedule set to Flex Daily Schedule.
