Android 9 “Connected, No Internet” Error Message Fix

In order to join the Rain Bird LNK WiFi network during the setup process on a device running Android 9, the ‘Location’ permission must first be granted in the Rain Bird mobile app. Follow the link below for a step by step process.

How to Enable Location Services in Rain Bird Mobile App on Android 9

 

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.  You can verify what zip code is set in the timer by tapping the controller card > Settings in bottom right > Controller info.

The weather forecast reported in the Rain Bird App is taken daily around midnight and used to automatically adjust irrigation when this feature is enabled.  Since weather forecasts can change by the minute, there can be differences between the weather forecast displayed in the Rain Bird App and major weather service websites during the later hours of the day.

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.

Why is my Automatic Seasonal Adjust reducing run times on a hot day?

Your Automatic Seasonal Adjustment percentage value may be different than you’d predict for any particular day.  An adjustment value of 100% is representative of irrigation during the hottest time of year, so even if you are experiencing unseasonably warm weather on a summer day, you may not see an adjustment above 100%.

The three factors Rain Bird considers when creating your daily automatic seasonal adjustment value are:

  1. Historical average weather (temperature, humidity, wind speed, etc) for your postal code for the current month.
  2. Adjustment to account for yesterday’s automatic seasonal adjustment accuracy given yesterday’s known weather.
  3. Adjustment to account for tomorrow’s weather forecast.

If your observations over several days show an irregular trend, then you might contact the Rain Bird support desk.  Please be sure to include your LNK WiFi Module MAC address (serial number) and postal code.

Notifications

How do I enable notifications?

Be sure that you have Allowed Notifications for the Rain Bird App from your smart devices’ Settings -> Notifications menu.

Android: To enable notifications, first go to the Rain Bird mobile App’s settings (upper left hand corner gear icon).  Inside the app settings enable global Notifications.  Next, navigate into the controller card.  Once connected, select Settings icon on the bottom right corner.  Expand the Notifications selector and enable each notification that you would like to receive for this controller.

iOS: Navigate into the controller card.  Once connected, select Settings icon on the bottom right corner.  Expand the Notifications selector and enable each notification that you would like to receive for this controller.

What do the notifications mean?

WiFi Stick Reboot – A notification will be sent if the controller loses power or if the WiFi Module resets.

Date/Time Error – A notification will be sent if the controller’s date and time seems to be incorrect.

Shorted Solenoid Detected – A notification will be sent if the controller is capable of sensing a shorted solenoid on a connected valve.

Controller Experienced WiFi Disconnection – A notification will be sent if the controller has been properly connected to a WiFi router and experiences disconnection. The notification will also indicate whether the WiFi signal strength is strong or weak. If the signal strength is weak this typically indicates the controller is at the edge of the WiFi range of the home’s WiFi router’s range.

System Access AP Mode via Local Button Push – A notification will be sent if the WiFi Module has been accessed in AP/Hotspot mode locally at the controller.

Delay Watering Enabled – A notification will be sent if any user enables delay watering feature. The notification will indicate how many days the system will not water before continuing regularly scheduled watering times.

Automatic Seasonal Adjust Applied – A notification will be sent if the controller receives an updated seasonal adjust value from the Rain Bird server based upon programmed ZIP code’s weather changes

Freeze Warning – A notification will be sent if the server indicates low temperature of the day is below 35 degrees Fahrenheit.

Irrigation Event Complete – A notification will be sent when any irrigation event completes. The notification will include the number of minutes of irrigation as well as the date and time the event completed.

WiFi Connection

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.

Why can’t I access or find my controller through the Cloud?

This can be caused by several factors:

  1. The controller is not connected to an Internet connection properly within your home WiFi network
  2. The controller is unable to establish a connection with the Rain Bird  server
  3. Your mobile device’s controller password does not match the controller (password reset required).

If I do not have a 2.4 GHz network available, what do I do?

The industry standard for the majority of WiFi router manufacturers maintain the capability to connect to a 2.4 GHz network directly upon powering up the router. If the router has both 2.4 and 5 GHz capability, then this will be viewable for the majority of routers in the WiFi network (SSID) name. The suffix of the network name should indicate whether it is 2.4 or 5 GHz.

In the event that a 2.4 GHz network is not available from your list of selectable networks, please refer to your router manual or IT specialist for further information.

Can I extend the range of the LNK Module’s AP Hotspot without using a local WiFi network?

Yes, you can boost the signal of the LNK WiFi Module’s hotspot to extend its range using a commercially available WiFi signal boosters that operate on 802.11 b/g/n 2.4GHz signals.  Simply configure your wifi signal booster to connect to the Rain Bird wireless network while the LNK is in hotspot mode (blinking green/red).  The amount of range extension you can achieve is a function of the strength of the booster and your local environment.

Can I use a guest (unsecured) WiFi network to operate this product?

You are able to use any of the WiFi network connections, guest or otherwise, so long as they are Internet connected and are 2.4 GHz WiFi networks. The Rain Bird LNK WiFi Module will not connect to 5 GHz WiFi networks.

*Internet Connectivity is required for Rain Bird to provide firmware updates to your Rain Bird LNK WiFi Module in order to further ensure product stability.

*Internet Connectivity is required for access to your controller outside of your local WiFi network.

My WiFi signal strength is strong, I selected my WiFi network from the list, and I entered the correct password but it will not connect.

Double check the password is entered with the correct capitalization. There is a switch to see the entered password that can be used to verify this.

During WiFi Setup I am getting an error: “Please connect to the controller’s AP”

The mobile device is no longer connected to the Rain Bird network. Return to the WiFi mobile device settings and reconnect to the Rain Bird network. Then return to the Rain Bird app and verify the WiFi name and Password and tap “NEXT.”

What is the range of the LNK WiFi Module’s wireless signal?

The following table lists the typical expected operating range, which is dependent upon the connection mode:

Mode Indoor (feet)
802.11b 115
802.11g 125
802.11n 230

**WiFi range can be affected by materials in the range path, in particular dense materials.

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.

Android Instructions: Navigate to “Lock screen and security” in the Settings menu.  Enable “Unknown Sources”.

Does the LNK WiFi module need to be set up again if I lose WiFi and/or power?

No, the LNK WiFi Module should reconnect to the local WiFi connection after losing, then regaining power or losing, then regaining WiFi service. A optional notification informs the owner when a connection is restored. If reconnection is not occurring, it is possible that the LNK is getting a weak WiFi signal. If this is suspected, checking the RSSI value in the App. If it is -70 or larger (-70’s, -80’s, -90’s) the Controller is too far away from the WiFi router.

During the provisioning process, after entering my WiFi SSID and password, I received a Communication Error, and I cannot complete setup. The LNK is blinking green indicating it is connected to WiFi. What is happening?

The App is designed to check that your LNK WiFi Module is successfully connected to your selected WiFi network by connecting your phone to the same network.  It is possible that your phone automatically reconnected to a different WiFi network than what you set up your LNK WiFi Module.  Try the following:

  1. When receiving an ‘setup unsuccessful’ message from the Setup Wizard, check to ensure your phone is connected to the same local WiFi network as your LNK WiFi Module and click “Retry”.
  2. Restart the setup process by pressing the button on your LNK WiFi module (flashes red and green) and go through the process again, this time ensuring that your phone reconnects to the same WiFi network as the LNK Module is set up for.

What can I do if I can’t see the LNK’s WiFi signal during setup?

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 controller’s wireless network, ensure the WiFi Module’s status indicator is alternating between Red and Green.  If it is not, briefly press the button on the WiFi Module.  Once the WiFi Module is alternating Red and Green, rescan for the network on your phone.  If this does not remedy, please disable and re-enable WiFi on your smart device; as occasionally smart devices scanning for WiFi networks need to be refreshed.

I’m a contractor who would like to manage controllers for my customers. How can I do it?

If you are an Irrigation Contractor you have the option to set up your customer’s LNK WiFi Modules on your device:

How To Use

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.

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.

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.

My phone is unable to open the .rbcf file I received as an emailed invitation to access my Rain Bird controller. How do I fix this?

If your phone will not allow you to select the Rain Bird application while opening the .rbcf file in your emailed invitation, please first ensure that you have installed the latest Rain Bird App on your phone or smart device by visiting the Apple App Store or Google Play Store.

Then check your phone’s Email and Security settings to temporarily allow unrecognized or unknown file types.  Try saving the .rbcf file attached in the email invitation and opening it from your phone’s memory or cloud storage.  If prompted for an application associated with the .rbcf filetype, navigate to the Rain Bird App and open the file.

My 2018 Samsung or Android based phone will not let me connect to the Rain Bird WiFi hotspot during setup? How do I fix this?

  1. Temporarily turn off the smart networking feature on your phone, or simply turn Airplane Mode on, then turn WiFi on (while Airplane Mode is still active)
  2. Reconnect to the Rain Bird WiFi network (RAINBIRDXXXXX) and follow the on-screen setup instructions as normal.

Some 2018 phones using Android operating systems (typically version 7.X) have introduced ‘smart networking’ features that prevent connection to WiFi hotspots that do not have internet service.  Taking these steps bypasses this feature so that the Rain Bird WiFi hotspot can be used during setup.

Why is my Automatic Seasonal Adjust reducing run times on a hot day?

Your Automatic Seasonal Adjustment percentage value may be different than you’d predict for any particular day.  An adjustment value of 100% is representative of irrigation during the hottest time of year, so even if you are experiencing unseasonably warm weather on a summer day, you may not see an adjustment above 100%.

The three factors Rain Bird considers when creating your daily automatic seasonal adjustment value are:

  1. Historical average weather (temperature, humidity, wind speed, etc) for your postal code for the current month.
  2. Adjustment to account for yesterday’s automatic seasonal adjustment accuracy given yesterday’s known weather.
  3. Adjustment to account for tomorrow’s weather forecast.

If your observations over several days show an irregular trend, then you might contact the Rain Bird support desk.  Please be sure to include your LNK WiFi Module MAC address (serial number) and postal code.

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.

Router Compatibility

Which routers are the LNK WiFi Module compatible with?

Security protocols supported include Open, WEP, WPA-TKIP, WPA-AES, WPA2-TKIP, WPA2-AES, WPA2-AES-TKIP.

LNK WiFi is not compatible with satellite internet service providers.

How do I know if the network I am trying to program the LNK WiFi Module to is a 2.4 GHz WiFi network?

When selecting an available network during controller setup in the Rain Bird mobile app, only 2.4 GHz networks that are within range of the controller will be available networks to select from.

Which router port is compatible with the LNK WiFi module?

Port 80.

Programming

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.

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.

Why is my Automatic Seasonal Adjust reducing run times on a hot day?

Your Automatic Seasonal Adjustment percentage value may be different than you’d predict for any particular day.  An adjustment value of 100% is representative of irrigation during the hottest time of year, so even if you are experiencing unseasonably warm weather on a summer day, you may not see an adjustment above 100%.

The three factors Rain Bird considers when creating your daily automatic seasonal adjustment value are:

  1. Historical average weather (temperature, humidity, wind speed, etc) for your postal code for the current month.
  2. Adjustment to account for yesterday’s automatic seasonal adjustment accuracy given yesterday’s known weather.
  3. Adjustment to account for tomorrow’s weather forecast.

If your observations over several days show an irregular trend, then you might contact the Rain Bird support desk.  Please be sure to include your LNK WiFi Module MAC address (serial number) and postal code.

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.
