What reviewers found
Aiper IrriSense 2
- Bob Vila (4.9/5): Set up in about 15 minutes and reliably ran twice daily schedules across two zones in a Florida yard for several weeks, skipping after rain and pausing on windy days. Source
- The Smart Home Hookup: Cup tests over three runs averaged 76 percent distribution uniformity, but it delivered less than half the depth set in the app; wind gusts tripped the rain sensor. Judged far better than the OtO it was tested against. Source
OtO Smart Sprinkler
- The Smart Home Hookup: Three cup tests averaged 47 percent distribution uniformity, with some spots getting over 4 times the water of nearby ones; a quarter inch run took 1 hr 48 min. Reviewer said it fundamentally fails as a sprinkler. Source
- Bob Vila (3.5/5): A month of testing in southern Ohio: easy setup, ran daily at 6 a.m. in hot weather and skipped watering during a rainy week. Source
