OpenSprinkler
Live today — assisted setupby OpenThings
OpenSprinkler is the open-source irrigation controller, and the first hardware Lawn Focus shipped with. Approved watering proposals write to the controller twice a day, scaled from your baseline programs, with a full audit trail.
How it works with Lawn Focus
- You approve a proposal in the app; it becomes an active adjustment with an expiry date.
- A bridge on your home network pulls the adjustment-only watering plan and rewrites program durations on the controller — baseline × adjustment, nothing invented.
- OpenSprinkler's Zimmerman weather adjustment keeps handling daily weather scaling independently.
- When adjustments expire, the bridge restores exact baseline durations automatically.
Getting set up
Beta setup (about 20 minutes, together)
During the friends & family beta we set this up with you: we record your current programs as the baseline, install the sync bridge, and run a dry-run before anything touches the controller. You'll need your controller's local address and password.
Every feature works today in manual mode
Photo reviews, proposals, and guardrails don't wait on hardware.
