Hi Jonathan,
Could you please send us the link of "Once weekly" watering and we will update our regulation database. Currently we only find water regulation from this website https://www.uplandca.gov/water-conservation:
- Odd number addresses water on Tuesdays & Saturdays
- Even number addresses water on Wednesdays & Sundays
You can also create a restriction to follow "Once weekly" watering through Settings->Restrictions.
Thanks,
Wency
