## Description
LNK2WIFI is Rain Bird's plug-in Wi-Fi module. It turns a LNK-ready ESP-TM2, ESP-ME3, ESP-Me (manufactured after November 2, 2016), ESP-RZXe, LXME2, or LXIVM into a cloud-connected controller on the free Rain Bird app — weather-based run times, remote start/stop, alerts, and shared access with the landscape contractor.
This is the Hydrawise competitor inside the Rain Bird ecosystem. If the valves and heads are already Rain Bird, LNK2 keeps the smart-control stack on the same brand. It is not IQ4 central control and it is not a Hunter WAND.
The module is 2.4 GHz 802.11 b/g/n only. Setup uses Bluetooth Low Energy, then the module joins the site router or falls back to its own hotspot. Operating power is 24 VAC from the controller accessory port (55 mA max). There is no monthly fee for the residential/light-commercial Rain Bird app.
EPA WaterSense is not the module alone. Pair LNK2 with a compatible controller and a Rain Bird rain sensor (WR2-48 is the usual pair). On ESP-ME3, add FG100 if you want high/low flow alerts in the same app.
