Hello Netro Support, 

The Spark startet watering today at 4 am as it was calculated by whisperer and weather. 3 Zones got water, but instead of watering 10 minutes the gras got 3 hours water. 

I wasted a lot of water, this is far away of smart watering. My old installation from Gardena / Husquarna never had such problem. 

The spark was not able to close the Ventils! 

The only way was the make the spark powerless. 

What’s wrong? 

Again: the test procedure of the ventiles works without any problem, spark open AND CLOSE every ventile step by step!
