Start Here: How to set up the OtO device

Getting your OtO unit set up for the first time? You've come to the right place. Start here for everything you need to know about getting your device set up quickly.


What's in the box

Each OtO box comes with:

  • An OtO unit
  • Steel mounting bracket with wood screws and thumb screws
  • Quick start guide
  • Power adapter with 50-foot cable (found INSIDE your device)

What else you need:



Using your OtO Device


Understanding the Wake Switch

📝Note: Some models may have a button instead of a switch.

  • To conserve battery power, OtO sleeps most of the time! It wakes up every 5 minutes and looks for commands from the cloud (you'll see it blink blue and then green).
  • If you are interacting with OtO and want to wake it up sooner, for example if you are using Manual Water or Manual Solution Application, turn the switch to wake OtO up.
  • If you are not physically with the device to wake it up, it will water on the next wake cycle.


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.

Teal / Turquoise Solid Updating to latest firmware
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

Your OtO device comes with a partial charge, but we recommend that you charge the device overnight using the provided wall plug prior setting up for the first time.

🔌 Can't find your power cable? Open OtO's lid and check inside. The power cable will be rolled up and nestled inside the middle (blue) solution bay.

  • Remove 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.
  • Plug in OtO: 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).
  • Charging status lightSee the hardware version on the sticker underneath the lid.
    • Hardware version 6014-C and 6014-CS: If the LED indicates solid red, this means the device is successfully charging. Note that once the battery is full, the light will turn off.
    • Hardware version 6014-F: The light will NOT turn off even when the battery is fully charged.

Step 2: Choose a location

Consider the following when you are picking a location to install OtO:

  • Range - Each unit has a max reach of 30 feet at 50 PSI.
  • Water - To maximize your flow rate, use a high-quality hose with an ID of at least 5/8 inches. Remove any connectors, kinks, or bends that might limit the flow.
  • Wi-Fi - OtO requires excellent connectivity to 2.4 GHz Wi-Fi signal. It will not work with 5 GHz.
  • Power - OtO can be entirely powered by the on-board solar panel IF it receives at least 3 hours of direct 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.

Caution: 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

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.

  1. Download the OtO Lawn app from the Apple App Store® or Google Play® store.
  2. Create an account.
  3. Follow the prompts to add a new device.
  4. Press the Wake Switch on the device to wake it up.
  5. Press "Connect to OtO" right away to connect to Bluetooth. You will know when it is successfully connected to Bluetooth when the status light glows solid blue.
  6. Name your OtO device.
  7. Once OtO is connected to your phone via Bluetooth, you will be able to connect it to your home's Wi-Fi network.
      • OtO can only connect to 2.4 GHz networks
      • If you have an iPhone, your phone will need to be connected to this network when you are pairing OtO
  8. Device will run a firmware update. This can take up to 5 minutes. 
  9. Once the firmware has finished updating, you can begin securing your device.


Step 4: Securing device

The OtO unit must be secured using the steel mounting bracket in the ground or on a fence.

Caution: Do not operate the device without securing it properly. Pressurized water will cause the device to tip over potentially damaging the device and will cause any solutions to leak.

Ground Installation


  1. Push the mounting bracket into the ground until the top is flush with the surface. Use a blunt piece of wood as a mallet, if necessary. If your soil is very sandy, you may want to first drill the bracket into a piece of wood or other support before burying it. 
  2. Screw the four thumb screws into the bottom of the device.
  3. Push the device 'feet' into the bracket holes until all four are clicked securely into place.

Fence/Wall Installation


Installing up high can allow you to reach slightly farther as well as avoiding obstacles.

📝Note: We do not recommend installing OtO higher than 3-4 feet as the water will be blown away in the wind.

  1. Use the four included wood screws to drill the bracket into a fence. We suggest using a level.
  2. Screw the thumb screws underneath the bracket and into the unit.

Optional: Security

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. The fun part!

Tip: 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.

  1. Ensure your OtO is attached to water, there are no leaks anywhere along the line, and the water is turned all the way on.
  2. Select Add a Zone from the device overview page.
  3. Tap Set Zone Boundaries.
  4. You will be able to choose from three types of zone boundaries:
    1. Spot - waters individual 'points' such as trees, potted plants, and shrubs
    2. Line - waters along a narrow line for lines of hedges or gardens
    3. Polygon - you define the perimeter, OtO fills it in. Great for lawns
  5. After selecting the zone boundary type, you will be prompted to active the Wake switch (or button) again. Turn the head away from you. The device will begin to water.
    • 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.
  6. Use the arrow keys to move the water stream towards and away from the device, and the curly arrow keys to turn OtO's head. Press and hold to make bigger movements. Tap to make small adjustments.
    • Spot: Simply place 'points' where you want OtO to water.
    • Line: Place points along the line of where you want OtO to water. The connected line will show you where OtO will water.
    • Polygon: Place points to define the boundary edges. OtO will 'fill in' the middle during a watering cycle.
  7. You can also edit the points you've set.
  8. Press Save to finish the zone.

You can set up unlimited zones per device.


Step 6: Demo zone boundaries

After saving your zone, you'll probably want to review what you've just set to make sure it is to your liking.

  1. From the Zone Overview page, tap the blue "Apply Manually" button.
  2. You may need to wake up OtO using the switch or button again.
  3. Select "Demo Zone" this performs a quick pass to show you where OtO will water. Actual cycles will complete multiple passes and put down much more water. The purpose of this mode is just for you to verify the zone location is correct. 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. On the Device overview page, select the bay to fill.
  2. Scan the QR code from the bottle. The device now recognizes this bottle, and you can assign it to the available zones.
  3. Remove the cap and carefully insert the bottle into the corresponding bay. Firmly connect the feed cap.


Step 8: Customize

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
  • 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
