Your OtO Device

Welcome to your new OtO device. Here’s how to interact with your device:

Understanding the Wake Switch

Effortlessly take the reins of your OtO with these intuitive features:

  • Conserving Power: Your OtO is eco-conscious, slipping into sleep mode and briefly waking every 5 minutes to await your direction.
  • LED Cues: Watch for the LED's blue glimmer when instructions are received or its green glow when actions are confirmed and completed.
  • Immediate Use: Eager to get started? Simply activate the wake switch or button, and your OtO responds in an instant.
  • Automatic Ease: When manual isn't an option, trust OtO to manage your watering cycles automatically, ensuring nothing interrupts your schedule.

Remember, some OtO models have switched to a button for even simpler operation.


Understanding the LED Light

Light Color Light Type Description



Important: You may see your OtO device LED light turn red in very low sunlight. This behavior is expected, however it needs to be in full, unobstructed sunlight in order to charge enough to operate without issues.

6014-F units stay red even when fully charged. If your unit has a sticker underneath the lid that says "6014-F", this means it is a 6014-F unit.

Blue Blinking Looking for Bluetooth
Blue Solid Connected to Bluetooth
Green Blinking Waiting for actions from the cloud

📝Note: LED may alternate red and any other color while it is charging and performing another activity at the same time. This is normal.

Step 1: Charge OtO Overnight

Charge your OtO overnight to ensure it's ready for action. It comes part-charged, but a full charge is best for the first setup.

🔌Can't find your power cable? Just peek inside OtO’s lid. The power cable is cozily coiled up inside the middle (blue) solution bay.

Charging Steps:

  • Access the Charger: The wall adapter and charging cable are placed within the solution compartment upon arrival. Lift the solar panel and remove it from the device body.
  • Connect to Power: The power port is located on the bottom of the device that is protected by a waterproof cap. Use a screwdriver or a key to leverage the plug out from under the device. Remove the waterproof cap and connect it to the provided wall cable (shipped to you inside the device).

Know Your OtO's Charge Light:

  • For 6014-C and 6014-CS Models: A solid red LED glow means charging is in progress. It'll switch off when fully charged.
  • For 6014-F Models: The LED stays red all the time, even when fully juiced up—check under the lid for a "6014-F" sticker to confirm your model.

Remember, charging is key to a happy OtO!

Step 2: Find the Ideal Spot for OtO

When deciding where to place your OtO, keep these points in mind:

  • Reach: OtO can water up to 30 feet away with proper water pressure (50 PSI).
  • Hose Quality: Use a high-quality hose (5/8 inches in diameter is perfect) and straighten out any twists for the best water flow.
  • Wi-Fi Connection: Make sure the spot gets a strong 2.4 GHz Wi-Fi signal; 5 GHz won’t connect.
  • Sun Exposure: The solar panel powers OtO with at least 3 hours of sunlight per day. If you live in a shadier area, we suggest using the included power cable or purchasing the External Solar Panel accessory. You will know if the device is charging when the LED status light glows red.

⚠️ Safety Cauton: Pressurized hose may burst in high heat. Do not leave your hose pressurized and exposed to the sun. In order to keep your drinking water safe from contamination, the faucet that OtO will be connected to needs protection from the possibility of water flowing backward. Commonly known as a backflow device, government regulations specify what type of backflow device is required to adequately prevent water from flowing backward when a device such as OtO is connected to the water supply. Since the type of backflow device and maintenance schedule required by regulation varies at the city level, OtO is not responsible for damage or harm caused by not installing and maintaining the appropriate backflow device for your area.

Refer to our Placement Guide for full details.

Step 3: Pair device

Time to get your OtO device paired to the app!

  1. App Download: Find the OtO Lawn app from your app store and create an account.
  2. Pairing Mode: Bring OtO to its new spot and use the Wake Switch to initiate pairing mode.
  3. Bluetooth Bonding: Tap 'Connect to OtO' in the app for a blue-light handshake.
  4. Wi-Fi Connection: Link OtO to your home’s 2.4 GHz Wi-Fi (iPhone users, join this Wi-Fi network first).
  5. Firmware Update: Your OtO might update its software now, which could take around 5 minutes.
  6. Name Your OtO: Give your device a name and celebrate – it’s now part of the family!

Step 4: Securing device

Now that your OtO is charged and paired, it's time to make sure it stays put. Bring your device to the location that you'd like to install it. Before mounting or securing it, we highly recommend you make sure the Wi-Fi signal is strong enough by pairing it to the app.

🎥 Watch Our Video Guide: We’ve created a helpful video tutorial, "How to Mount an OtO Lawn smart device," available below. It’ll take you through the process step by step.

⚠️ Safety Caution: A loose OtO is a no-go. Secure it tightly to prevent any tumbles or spills. If OtO’s not stable, the water pressure could knock it over, leading to damage or leaks. The OtO unit must be secured using the steel mounting bracket in the ground or on a fence.

For Ground Installation:

  1. Insert the Bracket: Push the mounting bracket straight down into the ground until it's even with the ground. For sandy soil, secure the bracket to a piece of wood first.
  2. Attach Thumb Screws: Fasten the thumb screws to the bottom of the OtO unit.
  3. Lock in the 'Feet': Press the device down onto the bracket until you hear all four 'feet' click firmly into place.


For Fence/Wall Installation:

  1. Position the Bracket: Hold the bracket against the fence or wall at the desired height (no higher than 3-4 feet to avoid wind issues). Check with a level to ensure it's straight.
  2. Drill in Place: Secure the bracket using the four wood screws provided.
  3. Attach OtO: Finally, screw the thumb screws into the bracket from underneath to fix the OtO unit in place.

📝 Note: A higher position can extend OtO's reach and avoid obstacles, but keep it within 3-4 feet above the ground to ensure the wind doesn't interfere with the water's path.


Security (Optional):

For added security, you can lock your device to a permanent structure by attaching a light chain and padlock to the steel loop at the bottom of the unit.


Step 5: Set zone boundaries

Once you've mounted your unit in your desired location and paired to the app, you're all set to begin setting zone boundaries with your OtO device. Ready to tell OtO where to water? Here's how:

  1. Connect to Water: Check that OtO is hooked up to your water supply with no leaks and fully turned on.
  2. Add a Zone: In the app, find 'Add a Zone' on the device page, name your zone, and select 'Add Zone.'
  3. Select Zone Type:
    • Spot: Directly on target areas.
    • Line: Along garden rows or hedges. The connected line will show you where OtO will water.
    • Area: Place points to define the boundary edges. OtO will 'fill in' the middle during a watering cycle.
  4. Activate OtO: Hit the Wake switch or button to get OtO ready. Turn the device's head away from you.
  5. Begin Watering: Use the 'Water on' toggle in the app to start.
  6. Position Water Flow: Move OtO’s head with the arrow keys to aim the stream.
  7. Place Points: Set zone boundaries by tapping the plus sign on the app’s map:
  8. Save Your Zone: Confirm your settings with the 'Save' button.

Tip💡: The first time you turn on OtO it may 'sputter' loudly. This is normal and just means air is coming out of the system. Also, install your device and set up your zones on a sunny, calm day. Setting up when there are high winds may make your zone barriers inaccurate, or the device will not be able to water at all.


Step 6: Demo the zone boundaries

After saving your zone, it's time to see OtO in action!

  1. Apply Manually: Head to the 'Zone Overview' in the app and press 'Apply Manually.'
  2. Wake Up OtO: You may need to give OtO a nudge with the Wake switch or button.
  3. Demo Zone: Choose 'Demo Zone' for a sample show of OtO's watering path. NOTE: OtO sleeps to conserve battery power. You may need to wait up to 5 minutes for OtO to wake up and for watering to begin when using the Apply Manually function.

Step 7: Add solutions

Once you've finished creating all the zones you want. you're ready to add your solutions such as fertilizer and pest control.

  1. Select Bay: In the app, choose which bay you want to fill with your solution.
  2. Scan QR Code: Let OtO recognize your solution bottle by scanning the code.
  3. Insert Bottle: Pop the cap off, place the bottle in the bay, and secure the feed cap.

And just like that, your OtO is not only set up to water but to nourish your garden too!


Step 8: Personalize your OtO settings

The OtO app was designed to be flexible so you can set your device to run the way you want! Each new zone you create will come with a default application schedule of three times per week at 6:00am, however you can change this at any time.

In the zone page, you can:

  • Edit the Zone Schedule
  • Edit the Solution Application Schedule
  • Edit the Watering Limit
  • Edit Zone Boundaries
  • Duplicate the Zone (for multiple scheduled waterings a day)
  • Toggle Solutions on or off
  • Toggle Weather Intelligence on or off
  • Rename or Disable a zone

Taking Care of OtO 

In order to keep OtO running in tip-top shape, please remember:

  • OtO should only be used with cold water
  • Never let OtO freeze
  • Do not submerge OtO
  • Periodically wipe the solar panel with a clean cloth to remove dust and keep it running as efficiently as possible
  • Keep the battery healthy by putting it in Winter Mode when not in use
  • Keep OtO's power plug (the red part) capped and tucked inside when not in use to prevent it from getting wet
