Misleading Functionality
The phone app allowing remote control of the controller is cute but I feel most people have little need to manage the device remotely. The main reason that I purchased the device is to get an accurate daily forecast and make appropriate modifications to zone run times either by increasing due to higher than expected temperatures or decreasing if forecast is lower than the "average" historical expected temperature. Sounds great....except it does NOT work with accurate forecast information. I expected the forecast to be taken directly from the closest National Weather Service to my zip code (approx. 20 miles away). Well surprise...when I questioned Rainbird support, they could not explain the source other than saying it originated in the "cloud". Well the cloud has to derive the forecast information from somewhere (apparently unknown) because the daily forecast was as much as 20 degrees off from the National Weather Service! Furthermore, it only reduces zone times if the forecast is cooler than expected but DOES NOT increase times if the forecasted temperature is higher than the historical average. If you are someone that just enjoys playing with phone applications, then go for it. If you expect it to be actually automatically useful in accurately managing water usage, don't bother.

hasn't worked since I installed it
I can use it as long as I'm standing right next to my irrigation clock. Yes, that's the only place it works.

Rain Bird tech geeks have been very receptive to my problems, but that's not helping with my review.

I've had it for 3 weeks now and it doesn't work.

Seems like it's not quite ready for prime time yet.

Not quite ready for prime time!
Install on ONE (Apple) device only; no Android or Windows. Have only one SSID in your home. Have your wireless router close to the control box. Under those limited conditions, this will work. Deviate from any of the three, and it will be hit or miss whether it works or has a Communication Error.

It would be nice to have a simple web-based interface as well, such as Honeywell has for its thermostats, so that you can work without an IOS app from any computer. It would also be nice if a second device didn't break the communication. And it would be really nice IF IT WORKED EVERY TIME!

A good convenient product
This WiFi link to the Rainbird controller is a good, convenient product. It gives the user control over his irrigation controller and makes it very convenient to access the controls remotely. It is much better than the Hunter irrigation controller which is totally WiFi and which perhaps looks better on paper than this Rainbird WiFi module, but the Hunter suffers from its WiFi-only interface. This Rainbird WiFi module gives the user some very useful options and it blends nicely with the manual knob interface on the Rainbird controller. It also holds the potential of using local weather forecasts to modify the programmed on/off times, but at this time the Rainbird does not have all of the supposed features of the WiFi Hunter controller. But at least the Rainbird WiFi interface works and gives the user the fallback option of the old manual interface.

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.

Totally worth the money
So glad I bought this. It’s ten times easier to control my sprinkler system through the app on my phone than through the unit in my garage, especially because the device is in an inconvenient spot. During setup, it gave me a warning that the WiFi signal was weak, but I’ve been able to use it everywhere in my house, so no problems there.

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.

Changing settings are super easy--uses local wether too
Easy to install and update the schedule. Uses local weather as well to change watering times as needed.

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.<br /><br />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.
