Rain BirdLNK2WIFI WiFi Module - 2nd Generation LNK WiFi - Compatible with All WiFi Controllers Including ESP-ME3, ESP-TM2, ESP-Me WiFi -

Funciona excelente, tomas el control de tu riego con una app. Muy recomendable y facil de instalar.

Using in a 6-station Rainbird TRU controller mounted in my garage. WAP is located in nearby guest apartment immediately adjacent to garage—so WiFi signal is strong. Has to use 2.4 GHz band, but as far as I know, all routers and WAPs that have 5GHz are dual band with a 2:4 GHz band as well. At first I wondered if I would use the remote controlling feature enough to justify the (considerable) expense of this module. Well—I love the convenience! Use it all the time—never use the controller front panel. Programming is much easier through the app, and in case of rain, the rain delay feature is a visual “slider” that you advance to the number of days you want to skip before the watering schedule resumes. Works like a CHARM. I cannot compliment the software enough. (One other thing—there was a glitch during initial setup and the WiFi connection never completed—got the spinning circle that did not go away. Just started all over and no problems the second time. Has worked perfectly since.).I first struggled with whether to add the LNK2 to my TRU controller or—for less $$—return the new TRU and buy the WiFi-control-only ARC8 for lower cost than the LNK2 alone. I was concerned that someone (family, sprinkler repair personnel) might need to control the unit in my absence, so bit the dollar bullet and got the LNK2. But to my understanding, the ARC8 software is exactly the same. For some people, that might be a cheaper way to go.In the case of the TRU controller, I didn’t see how the LNK2 would fit when looking at the TRU with the wire cover off. Ends up thr LNK2 does extend below the bottom edge of the back of the housing, but the cover is taller at the bottom than the controller back, and it easily covers thr LNK2. See picture.

So convenient to operate/program each zone from your phone. No need to only operate at the control box in the garage. Just walk around the property with your phone in hand to check the operation and coverage of the sprinklers heads. Nice ability to control the system from a remote location.
