I agree the user interface is VERY poor.  I’ve had my Sprite-12 for 5 years and I don’t think the software has ever been updated.  It’s always a pain to modify or add a program.  The thing does work however.  I found it helpful to have my 10 zones on spread sheets.

Dear customer,

If you do not want smart zone schedule to override your own programmed schedule, you can set up the Smart Zone level from Advanced to Basic through Settings->Zones->Smart Zone , which only skip rainning days for your programmed schedule.

If you want to create your own programs and turn off smart zone feature and rain delay feature, go to Settings->Zones->Smart Zone (Settings->Garden->Smart Zone for Pixie Timer) and toggle the enable button. When the smart zone is disabled, the system will strictly follow the user program to water the zones. There is no intelligence here. Netro will not skip your schedules when there is rain. Regulation feature will not be in effect as well.
