Works great with full function
Great item. Allows just about full use of sprinkler controls via any wi-fi connection. It's nice to be able to use remotely to make changes based on weather or even at home not to have to go to the box to make changes. Well worth the money for what it provides.

Works well
I bought two of these because I have a separate mosquito controller from the sprinkler system. Having the ability to program it from my phone is a luxury, but it helps me know when it runs when I'm not a home. It's also more intuitive than interface in the controller.

The reason I upgraded my controller!
My old controller could not be easily controlled remotely without purchasing a dedicated system that cost more than I paid for the controller! This module just plugs into the new controller, and a couple minutes is all it took to download the app onto my iPhone and sync the module. Now I can operate my sprinklers from anywhere I have access to the internet by WiFi or by cell service. NOTE: Before purchasing this product, ensure that you have a good WiFi signal where you plan to install it, as it requires that to work. In my case, I moved a network extender closer to the garage and it worked fine.

Would buy The Rainbird WiFi Controller from Sprinkler Warehouse again! What a convenience!
The feature that I like the most about the wifi system is the ability to customize your zones. I have 3 programs preset for varying run times and dial them up instantly depending on recent rainfall.
I keep a close eye on my lawn and if I see a dry area I pull my cell phone out and dial up that zone. So convenient
I love dealing with Sprinkler Warehouse and Rainbird. They both assisted me in setup (which was actually easy), but I wanted to verify everything.
I was skeptical at first whether or not I would get the use out of the wifi system. I now use it almost every day.
Oh yeah, it's really nice if it rains and your sprinklers are on to just reach for your cell phone. (My controller is outside.).

WIFI module / Setup and use
I like the idea of the WIFI control for the ESP4ME controller, and it works very well. I can now turn the irrigation system on/off from anywhere in the world.

I used the 3 station modules from my old controller, but will soon replace them with the updated 6 station, slimmer modules.

What I do not understand is why each time the smartphone APP for WIFI module is opened, the APP has to reload the settings and schedules for the controller. I don't have another APP that does this anything similar to this. It seems to me that the APP should be capable of storing that information and only reloading the settings upon demand. But otherwise, this is a great leap forward for Rainbird.

It would be advantageous to control the irrigation while away from home.

In addition to this purchase I had to also purchase and change out my Rain Bird ESP-Me controller to the new Wi Fi model. Changing controller, inserting the wi fi adapter and setting up the system was easy. I can now run my 22 valve system from any wi fi spot and make changes, change watering schedules, etc.

Changing and setting up the system was very easy.

The LNKWIFI and ESP4ME. Will the wifi unit override the settings already on the unit?
A shopper on Nov 21, 2016
BEST ANSWER: It will if you change it using the Rainbird app that connects to the controller. The wifi module just lets you access settings on the controller from your phone anywhere. You can do any setting modification you want at that point.
does the LNK WIFI module have an ethernet connector for hardwired applications?
A shopper on Apr 9, 2018
BEST ANSWER: It does not. It is simply a wifi connected piece of hardware. There is no other way to connect to it or it connects to anything else.
A shopper on Jan 6, 2017
BEST ANSWER: Unfortunately, I have no idea. But if the experience have had with RainBird I would say NO!. It seems RainBird has release I nice product but it will not function in the same model controller that were manufactyred before Nov 2016,
Dont trust anyone that tells you otherwise.
What kind of distance does the LNK wifi have?
jeff N on Jul 17, 2018
BEST ANSWER: I’m not exactly sure as to the specifications of this unit but it greatly varies on your wireless network ex. router distances vary greatly depending on your router. I can tell you that my Rain Bird control module is in the front of my home and my router is all the way in the back and it still picks up the signal with full bars.
