@mry110, I'm sorry to hear you're having trouble getting your Generation 1 controllers to BlinkUp. I'd recommend reviewing this support article. If you're still having troubles, please contact support at 844-472-2446 or firstname.lastname@example.org
At this time, we do not offer prioritized watering for restrictions. You'll need to create watering schedules that comply to your local restrictions.
Do you have any drip zones? Sometimes drip zones can be watered outside of the restriction hours. Alternatively, perhaps you could water some zones less than 1 hour per day? If you could water each zone for 45 minutes, this would total 12 hours for 16 zones.
