Do I Need WiFi To Use This Product

Do I need WiFi in my home or business to use the Rain Bird LNK WiFi Module?

You do not need WiFi in your home or business to use the Rain Bird LNK WiFi Module. However, you will not be able to use some of the product features without WiFi access, such as notifications, weather data, or daily Automatic Seasonal Adjustments. You will only be able to connect to the controller to make schedule and settings changes to the controller or operate your system manually from the Rain Bird mobile app in Hotspot mode.

What is Hotspot Mode?

Hotspot Mode is a simple remote access mode to your controller with the Rain Bird mobile app. To use this product in Hotspot Mode without programming the LNK WiFi Module to a local WiFi network, complete the following steps:

1. Press the button on the LNK WiFi Module and observe the LED flashing pattern alternating Red and Green.

2. Open your mobile device’s WiFi connection menu and connect to the Rain Bird network.

3. Open the Rain Bird mobile app and connect to your controller. If you have not setup a controller, please refer to the “Quick Start” topic of this FAQ or to the Quick Start guide included with the product.

Error Messages

Controller is Busy

If you receive this message when attempting to connect to the controller, this means another smart device is currently accessing the device.  Only one mobile device can connect remotely to the controller at a time.

Manual Time Out

Establishing communication to the controller timed out.  It attempted to connect to the controller; however, the controller did not respond within an expected amount of time.  Try again, as in most cases, congested network connections can cause this to occur.

Controller Mismatch

This error will be displayed if the LNK WiFi  Module has been moved from one controller model type (e.g. ESP-ME) to a different model type (e.g. ESP-TM2) and you are trying to communicate with the new controller type using the previous controller card (linked to prior model) in the mobile app.

If you move the LNK WiFi Module to a new controller type, you will need to delete the controller card linked to the first controller type and then go through the setup process again to associate the LNK WiFi Module with the new controller type.

Lock Out

The encrypted password in the Rain Bird mobile app for this controller does not match the encrypted password in the LNK WiFi Module and the user attempted to connect with the wrong password more than 3 times.  This locks out the controller from being accessed remotely for 15 minutes.

How To Use

What happens if I leave the app open?

If a user leaves an app open, the App will disconnect from the controller after several minutes.  Reconnection can be established by selecting the controller from the primary screen.

How can I allow my irrigation contractors access to my controller via their app for service?

Simply click on the envelope icon to send a temporary or permanent access invitation.  If you’d like your contractor to help configure protected controller or network settings, you’ll need to share the controller password with them.

Can I stop an active watering cycle using the app?

Stop a manual program cycle: After initiating a manual program cycle from the Home screen, you can press the “Skip Next” button (appears green when program is active) under the Program that is running until all zones are skipped.  The “Skip Next” button then turns grey indicating that the watering cycle is stopped.

Stop an automatic program cycle: After the automatic program has started, select the controller that is running from the main menu.  Scroll to the program that is running, and select the “Skip Next” button until all zones in the program are skipped.  The “Skip Next” button turns grey indicating that the watering cycle is stopped.

Stop a manual zone cycle: Select the water drop icon at the bottom of the home screen to enter the Manual Zone screen.  Any zone on the controller can be manually stopped or started using the “Start” and “Stop” buttons at the bottom of the Manual Zone screen.

How do I activate my sprinklers manually?

There are two active methods that you can use to activate your sprinklers manually.
1. You can manually run a zone by selecting the “water drop” icon on the controller card present in the Rain Bird App home screen
2. You can manually run each program or zone by accessing the controller card and selecting which program or zone you would like to run manually by expanding that program or zone card and selecting “Run”.

How do I program my controller with the Rain Bird App?

Once the Rain Bird App is able to communicate with the LNK WiFi Module a “Controller Card” will appear in the application that resembles your controller.

You will need to “tap” on the controller card in order to access the programming settings for the controller. Tap the pencil icons on the respective programs or zones to edit your controller’s irrigation schedules.

How does the seasonal weather adjustment work?

The seasonal adjustment takes into account several factors when determining the daily seasonal adjustment value including:

  1. Historical weather trends
  2. The previous day’s forecasted weather versus actual weather (temperature, rainfall, wind)
  3. Tomorrow’s forecasted weather

For seasonal adjustments to work effectively, set your programmed watering schedule should be set for the hottest month of the year. When temperatures, humidity, and wind values exceed what is typical, the seasonal adjustment value can exceed 100% (0% for ST8-WIFI, ESP-RZXe). When these values are below normal and for cooler months, the adjustment value can be below 100% (below 0% for ST8-WIFI, ESP-RZXe).

Can I have more than one device connected via the Rain Bird app to my controller at the same time?

No.  In order to avoid programming conflicts, only one connection is allowed at a time.  Once a user exits the app, it may take a minute before another user can access it.   If you exit the controller by selecting the back button from the controller main menu, another user can log into the controller immediately.

If the power goes out do I lose the schedule on my controller?

No, Rain Bird controllers contain a non-volatile memory inside the controller that keeps programming without the need for a battery backup.

Why did my controller water after we had a big rainstorm if I have a rain sensor connected?

Your rain sensor may not be working for the following reasons:

  1. Your rain sensor may be in an area where it is not exposed to the rain AND/OR
  2. Make sure the rain sensor is set to Active (not Bypass) in the Rain Bird Mobile App.

Can I use a rain sensor with my WiFi controller with the LNK installed?

Yes.  All Rain Bird WiFi enabled controllers have terminals for a rain sensor.  Remove the yellow jumper wire from the terminals marked “SENS”.  Connect both rain sensor wires to the rain sensor terminals per the rain sensor installation instructions.

Programming

Why does my controller still water even after turning it off?

If your controller is off and the water keeps running there is an issue with 1 or all the valves. When this happens it may be necessary to clean or replace a valve, or to call a contractor. For assistance in getting a contractor referral, please call: 1-800-RainBird.

I want to remove a controller from my app. When I click on the Delete (trash can) icon the timer card will not be removed. How can I fix this?

Make sure the mobile device is not connected to a different Rain Bird controller in hot spot mode. If it is, disconnect and try to delete the other controller. This should resolve the issue.

What does Automatic Seasonal Adjust do?

Automatic Seasonal Adjust allows the Rain Bird server to keep track of local weather based upon the programmed ZIP/Postal Code. The Rain Bird server will calculate a daily Evapotranspiration (ET) rate for each ZIP code and translate to an appropriate seasonal adjust value. The seasonal adjust value is then sent to each timer in that ZIP code. This is done every day to ensure the watering duration is increased or reduced as local weather changes. It is important that if you use this feature that the watering schedule is based upon the hottest/driest time of year.

Do I have to use the Rain Bird app to program the controller?

If you don’t have your mobile device handy, or your hands are dirty and you don’t want to use, it you can always program the controller via the timer’s front panel.

Why does my controller run through all my zones, stop, and then start all over again?

The reason why the controller is running again is because you have additional start times scheduled close to the first start time. Double check all of your start times and run times. If you have run times that amount to more watering time than the time between the start times, the watering program may begin again immediately after finishing.

Why is my controller not watering the run times I set the zones for?

Example: I set it for 10 minutes per station, and its watering 5 minutes per station instead.

This could be due to the Seasonal Adjust setting. Double check the setting in the Rain Bird Mobile App or at the controller. If the seasonal adjust is set for -50% when the run time is 10 minutes, it will only water 5 minutes per zone.

How do I program my controller with the Rain Bird mobile app?

Once the controller is added to the Rain Bird mobile app a “Controller Card” will appear on the mobile app home screen. Tap on the picture of the controller model within this card to access the controller. Tap the “pencil” icon within the controller’s existing program card(s) to edit existing irrigation programs. Tap the “+/- PGM” icon on the bottom left of the screen to create a new irrigation program.

Please view our Basic Features video for further instruction.

Troubleshooting

Why does my controller run through all my zones, stop, and then start all over again?

You may have programmed multiple start times scheduled close together. Double check all of your start times and run times. If you have run times that amount to more watering time than the time between the start times, the watering program may begin again immediately after finishing.

Why is my controller not watering the run times I set the zones for?

This issue is likely caused by the seasonal adjust setting. Double check the setting in the App or at the controller. If the seasonal adjust is less than nominal, the run times will be shortened accordingly.

Why does my system still water even after turning the controller off?

If your controller is off and the water keeps running there is an issue with 1 or all the valves. When this happens it may be necessary to clean or replace a valve, or to call a contractor. For assistance in getting a contractor referral please call: 1-800-RainBird.

Why did my controller water after we had a big rainstorm if I have a LNK Module and/or a rain sensor connected?

Your LNK makes daily watering adjustments but does not prevent scheduled watering events, and it may take more than 24 hours for the seasonal adjustment values to reflect actual rainfall.

Your rain sensor does not prevent irrigation after a heavy rainfall, it could be that (1) Your rain sensor may be in an area where it is not exposed to the rain (2) Your rain sensor is set to ‘Bypass’ in the controller settings (3) Your (wireless) rain sensor needs battery replacement or has malfunctioned.

How do I back up and restore my Rain Bird App so I don’t lose my settings and connected irrigation controller(s)?

You can back up your Rain Bird app, controllers, and settings to Apple  iCloud and Google Cloud.

iOS:  Settings-> Select Apple ID -> iCloud -> iCloud Backup (On)

Android:  Settings -> Backups (name may vary on different devices) -> Backup (On)

(or) Drive (Google Drive App) -> Backups -> <Select device from list> -> Gear/Settings Icon -> Backup (On)

To restore your backed up phone with your Rain Bird App to a different phone, you should be using the same operating system.  Please check with your mobile device supplier to ensure that the device you want to restore to has the same operating system as the App was previously installed on.

Weather

The weather shown is not accurate to where I am. What would cause this?

The weather in the app is based on the zip code set up for the timer. If you entered the zip code incorrectly, or are currently in a zip code that is different than then one at the timer, the weather may show what you expect. You can verify what zip code is set in the timer by tapping the controller card > Settings in bottom right > Controller info.

My weather info says “Unavailable”. Does that mean my controller is not working or connected?

Please be sure you have correctly entered your zip / postal code by navigating Settings-> Controller Information, and your LNK is connected to your WiFi network (blinking green light). If this information is correct, please wait 24 hours to allow the App to establish weather service.  If no weather data is available after 24 hours, please notify us at RainBirdApps@rainbird.com and provide us with your MAC address and postal code.

** Satellite Internet Service Providers may not allow support of weather info to the timer.

WiFi Connection

What can I do if I can’t see the LNK WiFi Module’s wireless network?

First, ensure you are well within range of the controller itself.  If you are standing next to the controller and still do not see the LNK WiFi Module’s wireless network, ensure the LNK WiFi Module’s status indicator is alternating between Red and Green.  If it is not, press the button on the LNK WiFi Module for one second. 

Once the LNK WiFi Module is alternating Red and Green, rescan for the network.  If this does not remedy the situation, please disable and re-enable WiFi on your smart device, as occasionally smart devices scanning for WiFi networks need to be refreshed.

Can my phone access the controller if there is no internet in my wireless network?

Yes.  This system does not require the Internet to allow the mobile app to talk to the controller, if the controller and smart device running the Rain Bird App are on the same local WiFi network.  However, there are certain features (such as automatic daily seasonal adjust and notifications that originate from the Rain Bird server) that will not work unless an Internet connection is available.

Why won’t the LNK WiFi Module stay connected to my WiFi network?

This is most likely due to the controller being on the far range of the WiFi signal broadcasted by your home’s WiFi router.  The best way to check this is to open the Rain Bird mobile app when it is connected and select the controller from the list of available controllers.

Once you are inside the expanded controller view, you can select the tab with the icon showing a WiFi signal. If the signal strength indicator has very few bars, this confirms the controller is on the edge of the WiFi range.  If possible, move the controller closer to the WiFi router. If this is not possible due to wiring or its location outdoors, the next best option is to attempt to move your WiFi router closer to the controller.

If the controller is unable to communicate with your home WiFi router at all, place the LNK WiFi  Module in AP mode and connect your mobile device directly to the LNK WiFi  Module’s broadcasted AP signal (Network Name: “RainBirdXXXXXX” where XXXXXX is the last 6 digits of the LNK WiFi Module’s serial number found on the back of  the device).

I have a controller on the outside of my home and I can’t get the connection to my Rain Bird LNK WiFi Module to work. My WiFi network connects to my phone. What can I do?

Some homes, especially those with exterior brick walls, have very poor WiFi signal outside the home. Try moving the router and the timer closer together, or add a wireless signal repeater (also known as a booster or range extender).

Why can’t I access or find my controller when I am not on my local wireless network at home?

This can be caused by one of several reasons:

  1. The LNK WiFi Module is not connected to an Internet connection properly within your home WiFi network, or
  2. The LNK WiFi Module is unable to establish a connection with the Rain Bird server, or
  3. The mobile device’s Rain Bird App and your controller’s passcode do not match.

Will my Rain Bird LNK WiFi Module ever need to be re-connected for any reason?

If you perform a simple router upgrade or change your Internet Service Provider, you may need to re-connect your Rain Bird LNK WiFi Module. (See “Change Router” or “Change Internet Service Provider”)

If I have a poor WiFi signal at my controller (App shows RSSI value in the -70’s, -80’s, -90’s) what can I do to improve it?

We recommend moving your wireless router closer to your irrigation controller, using a WiFi range extender, or adding another access point.

My LNK WiFi keeps losing its connection after a few days (blinking red). Why?

If you are able to connect to your LNK WiFi, but it occasionally loses its connection, this is likely a result of a weak WiFi signal. Check the RSSI value in the App. If it is in the range of -70 to -90, we recommend moving your wireless router closer to your irrigation controller, using a WiFi range extender, or adding another access point.

My router is very close to my irrigation controller (10 to 50 feet away) but I am still losing my connection (RSSI value reported as -70’s, -80s). Why is this happening?

Obstacles between the controller and the wifi router or booster can significantly degrade wifi signals, especially when installed outside the home. Things a WiFi signal will not pass through well include: cinderblock walls, sheet metal walls, cars, brick, etc. In these cases, it is recommended to use a wifi booster between the wifi router and the irrigation controller or moving the wifi router closer.

Can I use my phone’s cellular WiFi hotspot feature to connect my LNK WiFi to the internet?

Yes, most phone WiFi hotspot features can be used as the local WiFi signal to connect your LNK WiFi to the internet.  Be advise that if you use your phone as your WiFi router, you will not be able to access your controller remotely, and your carrier’s normal data charges will apply.
