Replacement sent to me worked
Previously I gave a one star review because the first device I received wouldn’t recharge after my initial use. For one reason or another, possibly user error. OtO sent a replacement device, for free, and it works perfectly. Be sure to get the device more than 3 hours of direct sunlight if using everyday. OtO app is easy to use, and works well. Well satisfied with OtO replacement device and the app.

Love it!!
Works great!!
Easy set up
Super easy set up. Does take a few tweaks to make it work as desired.
Wonderful
The OtO app is so easy to use and makes watering customizable. Love my OtO
Very good
Over all great product the only things need to be changed it’s the panel is pilling of on solar panel on top but working good so far
Seems intimidating/sets up in minutes
Much easier setup than I had feared. Works great!
Ease of use
Easy to use app, intuitive.
Works, but only if you have a single device.
Update 9/2026:
This is the most confusing app ever. Nice update guys.
Previously:
I really like the app, it works great for setting the zones…surprisingly well. That said, once you get more than one zone it doesn’t coordinate timing across zones. Water pressure requires only one zone run at a time, and with four oto devices, each with multiple zones, it’s a nightmare to coordinate this timing without overlap. Please improve scheduling support.

Fantastic product
Love it sooo much
Simple to set up and runs very quietly
I have a odd shaped lawn with flower beds on three sides. The OTO was able to set up a program to water my front using four different zones. It seems very efficient.
Buggy app
The weather sensing functionality doesn’t work, sometimes it doesn’t water according to the schedule and you’re not notified. Now you can’t even water manually because their backend systems are faulty.
Love OTTO
It is a great tool and saves me so much time and worry.
Best purchase!
It has been so simple to use and we love it!! Couldn’t be happier. We have one for the backyard and one for the front yard
New scheduling update is confusing
I liked the app better when you could set watering frequency based on each output. The scheduling system is confusing and was implemented poorly
My best buy this summer!
Fast to install and very easy to use! Love it!
Great product!
So easy to use
Great sprinkler
All I had to do was set 4 points and the sprinkler did the rest.
great app
Love the OTO, fully automatic
Great! Needs better weather reads
I love these little robots so much. The app is easy to use, I think my only thought is that the weather report it uses is wrong half the time and I have to override a skip or cancel a water when it’s actively raining.
The best!
Have had it since they came a few years ago and still loving them!
