Specifications

The LNK2 WiFi Module is designed for direct plug-in connection to the accessory port on Rain Bird ESP-ME3, ESP-Me, ESP-TM2, or ESP-RZXe Irrigation Controllers.
The connector interface shall have adequate mechanical resistance to prevent accidental disconnect during normal use while allowing easy tool-less insertion and removal by the user.
The LNK2 WiFi Module shall support direct WiFi communication to a mobile device through a 2.4GHz Band WiFi Access Point (hotspot) inside the LNK2 WiFi Module, or
through a LAN connection broadcast by an external WiFi router. At power-up, the LNK2 WiFi Module’s internal WiFi Access Point (hotspot) shall be automatically enabled if
a LAN connection is unavailable.
The LNK2 WiFi Module shall support network communications over a WiFi network connection.
The LNK2 WiFi Module shall utilize Bluetooth Low Energy during the setup process.
The LNK2 WiFi Module shall have a user-accessible push button for configuration and incorporates red, green, and blue (RGB) LEDs asstatus indicators.
Momentary push button presses shall toggle the LNK2 WiFi Module’s WiFi Access Point (hotspot) Mode functionality ON/OFF.
The LNK2 WiFi Module shall have a Factory Default settings reset feature that is accessed through the device push button.
• To execute a Factory Default, press and hold the push button on the LNK2 WiFi Module for 5 seconds.
The Mobile Apps weather report shall display the current day plus 4-day weather forecast for the target location. The source of weather data is as follows:

• United States: NOAA
• Canada: Environment Canada
• Europe: European Centre for MediumRange Weather Forecasts (ECMWF)
• Japan: Japan Meteorological Agency
• All other International: METAR

The Mobile Device App shall represent Controllers through “cards” that may be organized into groups. The Mobile App Home Screen contains all Controllers. Users can create additional Controller Groups with selected Controllers. Controller cards can be deleted manually by the user.
The Mobile App Home View Controller cards shall show an image of the Controller with name, type, the number of zones supported and interface icons for Remote, Calendar, Share and Delete features.
The LNK2 WiFi Module shall support server communications by connecting to (polling) the server at regular intervals. The server check-in interval is every 10 seconds.
The server shall enable Mobile Apps to subscribe to push notifications using Apple Push Notification Service (APNS) or Google Cloud Messaging (GCM).
The Server shall disassociate all Mobile Apps from an LNK2 WiFi Module that reported an access passcode change.
The LNK2 WiFi Module shall store a remote access passcode in nonvolatile memory and report an access passcode change to the Server. If a connection to the Server is not available at the time of the passcode change, the LNK2 WiFi Module shall continue to attempt to report the change until successful.
The LNK2 WiFi Module has no internal surge protection and relies on the Irrigation Controller’s Electrical Surge Protection features.
