Hello, I am leaving in Italy  have several whisperer devices in my garden and I would like to know if it is better to remove them during the winter season when my watering network is off? Thank you.

Controller light is off and displays Offline status. Rebooted router resulting in WiFI connections elsewhere in my house and to my other devices except for the Sprite controller. Repowered Sprite controller and also did a reset— same status with no light and Offline status. Help!

Three hours to setup 

Is this any good or just return now?

Does it keep causing problems?
