Preparation

1
Test the functionality of your irrigation system with your current controller first. If it does not work, please make sure it is repaired before installing the Sprite.

Note: If you are not sure about the condition of your sprinkler system, you might want to check whether there are shorted zones or open zones. You just need to use a multimeter to measure the resistance between the common wire and each zone. The normal reading would be 20-60 Ohms. If the reading is less than 10 Ohms then you might have a shorted circuit in the solenoid and if it is larger than 80 Ohms you might have an open circuit. Please contact us or irrigation professionals for additional support.


2
Unplug the power of your current controller.

3
Take a photo of the wiring in your old controller.
When you are wiring Sprite, this photo can be the reference.


4
Remove your current controller.

Installation

1
Check the strength of the WiFi signal at the location where your Sprite will be installed.
We recommend a signal of at least 2 bars on your phone.

Note: Sprite is unable to connect to Wireless-B(11Mbps) routers. Sprite only supports the newer standards, namely Wireless-N,Wireless-G and Wireless-AC. Sprite is incompatible with 5 GHz Wi-Fi networks.
Also, please make sure the SSID (name of your home Wi-Fi) does not contain special characters like spaces or quotation marks.


2
Remove the front cover from the base.

3
Install the Sprite base to the wall using the two screws included.
Use the air bubble to position horizontally.


4
Reconnect the wires to the terminals on the base.

Tips:
1. Use the picture of the wires on your old controller to help you remember.
2. The slot named “M” is for the master valve. In some controllers it is named as “PMV” or “P/MV”.
3. If the old controller has only one common wire, you can connect it to either one of the “C” slots and the other “C” slot will sit empty.
4. If you want to use your old power adaptor which has a ground wire, you can leave the ground wire open.
5. If you are not sure about the wiring, please send the picture of the wiring in the old controller to support@netrohome.com. Our customer service will provide quick support.



5
Put the front cover back on the base.

6
Plug in the power. Wait for 1-2 minutes, the light will be blinking slowly (once every second). If the light is stable or blinking fast (twice every second), press the RST button.

7
The network of your Sprite will be in its HOST mode (you will see a WiFi network named "Netro_lRC_xxx").
8
Download the free Netro app and start to configure.

Tip:
Search for "Netro sprite watering" on Google Play and App Store.


The LED Light

The LED light on your Sprite has three possible statuses:
Blinking slowly (on for a second and off for a second): this means the unit is in its HOST mode. This happens when you first plug in your Sprite or reset it, and indicates that it needs to go through the setup steps in the app to connect to a home WiFi network.
Solid: this means the unit is connected to your home WiFi.
Blinking quickly (on for 0.5 second and off for 0.5 second): This happens when you first set up your unit and did not enter the correct password, or whenever it loses its connection to the Netro cloud server.

The Reset Button

The reset button is located underneath the cover and is next to the AC adapter wiring slots. It is marked RST. You will need a pin or long, thin object to press the button.
Short press: to reset your Sprite to its HOST mode, simply press the button once for less than 1 second. Your Sprite should start blinking slowly in a few seconds.
Long press: to reset the unit to factory settings, hold down on the button for 6-8 seconds. Wait for 1-2 minutes, the light on your Sprite should start blinking slowly.

Troubleshooting

1. It is possible that your WiFi router is too far away. We recommend a signal of at least 2 bars on your phone. It is possible that your router is an old one and runs on Wireless-B (11 Mbps). Sprite only supports the newer standards, namely Wireless-N, Wireless-G and Wireless-AC.
2. In the app, select WEP mode below the password field if your router is using WEP encryption.
3. Double check the password. You should enter the password of your home WiFi, not the password of your Netro account.
4. Make sure your router has access to the internet and it is not blocking port 1883 which is reserved for MQTT. Rebooting the modem might help.
5. Sometimes, rebooting your router can resolve some connection issues.
That means your Sprite is unable to contact the Netro server. It will disconnect from your router and change back to its host mode in a few seconds. Please see the above question for solution.
Please press the RST button for less than 1 second, make sure Sprite is in host mode and the LED is blinking slowly(once per second).
Please make sure your router is turned on and has a signal of at least 2 bars on your phone at the location where your device is installed. Sprite only connects to 2.4 GHz Wi-Fi networks. You might also try to reboot your router.
Please check the wires. Are they loose or disconnected from the slots? Please also check the common wires and the master valve if you have one. If you believe the wires are correctly installed, you might want to check whether there are shorted zones or open zones. You just need to use a multimeter to measure the resistance between the common wire and each zone. The normal reading would be 20-60 Ohms. If the reading is less than 10 Ohms then you might have a shorted circuit in the solenoid and if it is larger than 80 Ohms you might have an open circuit.
If your app shows the device is offline, your Sprite is unable to connect to your home WiFi (possible causes: 1. your router is down; 2. Wi-Fi signal is weak; 3. the SSID/password is changed) or the router has no access to the internet. If your app shows the device is online, you do not need to do anything. There was a network glitch when the device tried to get the watering schedules from the cloud server. The light will be back to steady when it updates the schedules successfully in an hour. Reboot your sprite (unplug and replug the power) if it does not.

FAQ

There are two ways to test your sprinklers after installing Sprite: You can create an account and connect Sprite to your home Wi-Fi, then you can use the 'remote control' feature on the Netro app to turn on and off the zones instantly. If you just moved into a house and possibly have not installed the router, the "Test run" mode might work well for you: download the Netro app and use the "Test run" feature on the login page. In this way you do not need to have a home Wi-Fi or create a Netro account. Your phone is directly connecting to the Wi-Fi network hosted by the Sprite. This mode allows you to turn on and off the zones without involving the Netro cloud server.
Sprite is not designed to support the traditional rain sensors because those rain sensors do not forecast rainfall. For example, you usually do not need to water your lawn if the rain is coming tomorrow but your rain sensors will not tell you that. Netro has more advanced technology including real-time weather information to be aware of the rainfall in the past and also in the future. For even more accurate watering schedules, Netro offers wireless moisture sensors which measures exactly how much water your plants need. We believe these innovations that Netro is built with are changing the way of home irrigation.
Consider adding another Sprite. The Netro app is capable of managing multiple controllers. You can link two controllers together. You will need to have at least two"common" wires so that each controller gets one. If there is only one"common" wire, it needs to be connected to both controllers by using a wire splitter.
Sprite will re-connect to the Wi-Fi automatically after a power outage. Also, all the zone settings and watering schedules are saved on the cloud server, so you will not lose anything.
Sprite will continue to execute the pre-loaded schedules for up to one month.
Yes, as long as your phone/tablet has access to the internet, you can control and monitor your Sprite.
