Rain Bird LNK2 Smart WiFi Module (2nd Generation), Compatible with TRU Rain Bird Irrigation Timers and ESP-LXIVM, ESP-ME, ESP ME3, ESP-TM2, LXME2, RZXe Controllers Made After 11/2/16

Best thing ever! Awesome addition to my irrigation system. I read through many negative reviews and have decided that they must have been reviewing a different product than the LNK2 that I received. It was uper easy to install, connect to Wi-Fi, set up and start using. Took literally all of ~10 minutes, if that. Programming my irrigation system from the app is much easier than from the controller box. The app took a little time to figure out, but now that I have, it's very straight forward. I really like being able to monitor and control my irrigation system remotely from the comfort of my couch, or while on vacation in another state.

Plug and play. Works great, and it's a lot easier to adjust the controller using the Rain Bird app as opposed to doing it manually on the controller itself. Just be aware, when it asks you to set up a passcode for the controller in the app, make sure you stick to 4-8 characters or numbers. I mistakenly thought it was a standard password, and entered in something much longer. As a result, it chopped the PW off and I couldn't recover it. You then need to delete the controller from the app and reinstall it. It's just something as simple as a four digit code so you can share access to other users temporarily. But it also allows you access into the settings menu, so if you screw this step up, you won't be able to set notifications, etc. Other than that little error, I got it up and running in no time, and it is nice to be able to control my sprinklers when I am out of town.

Purchased this to simplify my sprinkler system, and itt did just that. After tirelessly working on the sprinkler system from the control panel I finally purchased this device and it all became so simple and now I can set zones, times, days and schedules all from my phone and never have to worry about my control panel

"It," being the LNK2WIFI Wifi module. The short answer for most people is "no." (But I think your should get one anyway.) The main benefit of this module is add remote control abilities to your existing WiFi capable Rainbird irrigation controller. As long as you have good 2.4 GHz WiFi reception at the controller**, this module will let you access all the features of the controller (via an app on your mobile device*) anywhere you have access to the internet. Other than turning on/off the controller, that is. If you are like most people, once you've dialed in your irrigation settings, you'll likely only access the controller for maintenance. Having said that, and since I'm spending your money, I think you should add this to your compatible controller (see list in item description.) If nothing else, just making the initial fine-tuning of your irrigation cycles more enjoyable. Compared to the cost of your irrigation system, this is a relatively minor expense. Raise your hand if you enjoy walking back and forth to the basement/garage where the controller is and where the valves are when you troubleshoot the irrigation system? Granted, a little exercise will do us all some good, but that's what gym memberships are for. Don't buy this for the promise of "additional capacities for additional feature sets in the future" in the ad copy. Just buy this because you want to remotely start the irrigation cycle or a specific sprinkler zone. Buy it because you want to tinker with your irrigation settings without having to go stand in front of the controller. What possible additional features could be added in the future? It isn't going to be 5 GHz WiFi. It's hardware. If there isn't a 5 GHz radio in there, it will never be able to connect to a 5 GHz network. A word about the app. It's functional, but it looks exactly like one of Rainbird's sell sheets. It doesn't appear to take advantage of the OS platform's UI elements. The app is functional, but I like my native apps to be, well, native. Here are the obligatory PRO/CON bullet points: PRO - Remote control of all your irrigation controller features. - Make available the "soak" feature that isn't surfaced on the controller. You get get around this by using an additional program on the controller, so it's not a big PRO unless you've max'ed out your programs. CON - 2.4 GHz Wifi - requires a WiFi network - IoT, connects to the internet. I recommend connecting this to an IoT only network, isolated from the main WiFi network where your computer and mission critical devices live. - the "automatic weather adjustments provide daily run time changes" feature appear to use weather info that is zip code based, which likely isn't specific enough for your use. It's one of those features that sounds good, but implementation is lacking. If you already have a rain sensor or soil moisture sensors connected to your controller, this feature is more questionable. - no access to the rain sensor data connect tot the controller. Basically, what the controller knows - the rain sensor stopped the irrigation cycle, but not how much moisture was detected by the rain sensor. *: It appears you can also access your controller, with this installed, via open source platforms such as "Home Assistant." **: I don't have issues with connectivity to the controller using the app. I do have good WiFi reception at the controller. You may consider a WiFi extender (or better yet, an additional access point) to provide more WiFi coverage at the controller.

This is the perfect item to turn my Rain Bird Sprinkler into a smart sprinkler. I love it! It was so easy to install and only took minutes. I first had to contact my internet carrier to request channel 2.4 GHZ. After that, it was easy Peezy. Love this item and would recommend it to all my neighbors.

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.

Amazing WiFi controller and app. It was so quick and easy to setup. And the app is so easy to schedule activity. So pleased with my purchase.

Works great, was easy to install... It took a couple times to get it to sync up w/my RainBird app, but nothing too complicated (And I have very little patience for things not to work). But now that it's installed and synched, it makes programming the controller a BREEZE! Highly recommend.

Works well with iphone. Detections could be simpler, but turn on/off your system from anywhere. Comes with seasonal adjustments and will not run during wet weather.

I do like it,

Worked perfectly ! Absolutely loved this control for my irrigation!

There were some initial WiFi connectivity problems for a while with the module used in quite close proximity to a router with a very strong 2.4G WiFi signal. The connection would drop every few days, requiring an inconvenient on-site reset. However, this problem went away after a module firmware upgrade and after reducing the router's WiFi signal strength a bit, and since then the WiFi connection has been stable, and the module has now worked correctly for several months with no further resets.
