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

This was part of a package deal for the new Rain Bird ESP-TM2 12 station Controller we bought to replace our 2004 Rain Bird Controller that had served us very well for 20 years. I submitted a review on the sprinkler system and it is an incredible system. This has only made the system even better than it is. This might sound lazy, but we can change the settings on our system from the couch, or from anywhere we might be on vacation. This is also made tying the sprinkler system into our home automation system and I thought it was something we really didn’t need, but it has made starting and stoping our system more convenient and changing the settings is know a few clicks away. I’ve read other posts where people are having issues with their wi-fi connection, even with a signal booster in the garage. We haven’t had any problems with the wi-fi not working properly and it is about 20 feet from the router. I’m not sure why people are having connectivity issues, unless other things like the water heater or furnace is in the garage area. This is easiest and best sprinkler controller that we have had. It’s easy for even the novice person to install. The setting up is simple, unlike our old controller. It’s completely digital and no moving parts like the settings on the older controller. The internet connection has only made it easier to access from nearly everywhere and there’s an app for it.

Bought this for our home. The Rain Bird System was already set-up in our home, but it did not have the Wi-Fi module key. I bought this so we could utilize the Rain Bird App on our phones and control the sprinkler system away from home. It works perfectly. The landlords of the house were super impressed. It is definitely worth the purchase. It was super easy to install it, it clips right into the system. The directions on the app are super easy to follow as well.

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.

I have a new home that had a RainBird irrigation controller installed. One of my neighbors had a different type and told me of the new smart features that allowed his irrigation controller to deliver just the right amount of water needed based on the current weather conditions. It was saving him many gallons of water each year and paid for itself in short order. I didn't want to replace my entire unit and saw that Rainbird offered a plug-in module that would give me some of the same data and functionality. So I purchased this module to add to my unit. I must say I do love the convenience. I can be anywhere I have an internet connection and control my house's irrigation remotely. I can be in the house or in the yard and manually run any zone I please for however long I like without having to be at the box mounted on the outside of my house. I can program changes directly from my phone. And, the remote unit now queries the local weather stations in order to adjust watering cycles based on local weather conditions. This is all very good. Our first water bill just came in since installing this module and it indicates that our water usage has dropped. What I don't know is how many gallons of water this unit has saved me. My neighbor's unit offers a much more detailed analysis and has more granular control than my does. However, for my needs, I am mostly satisfied with this add-on module. It was brain-dead easy to install and it paired up with my app on my phone seamlessly, so kudos for RainBird for that. I does give me regular updates that it is adjusting my watering cycles based on current regional weather conditions. For the price, I do wish that it included more data so that I could ascertain exactly how efficient this has made my irrigation system. But, so far so good. And if it saves me money by watering just what I need just when I need it, I will be more than happy with my purchase. Once I have more data I will try to update this review to give you more information.

Oct 2025: Great product. Saves you 1000's of galons water and money in a year. I have purchased this wifi module recently and everything has been great. You can program each sprinkler's zone and even adjust it for seasons. Meaning that you water less time in wet seasons and more in hot seasons. Easy to manage. Wifi connectivity is on 2.4 Ghz band and if you live in a place where there are too many interefering signals and wifi devices sending traffic on the same wifi channel, you may want to conside changing the channel to a low traffic one. Its a little hack to improve connectibity and responsivess of the module. All and all I love it so far. Update: Dec 31 2025: still works great and no lag no connectivity issue. Worths every single penny. Saved a lot of water!

Perfect. Works great!

We have a Rain Bird ESP-TM2 series controller for which I purchased this module. The controller has an open slot for a WiFi module and this one plugged right in. Setup took less than 10 minutes after downloading the Rain Bird app. The controller connected easily to our WiFi router and signal strength is very good The Rain Bird app provides the ability to change schedules, length of run times, and the addition of zones. We only have a single zone but our controller / module combination will handle up to four. During set up you will pick a few parameters, including soil type. It also automatically knew the rain sensor was connected and active. The controller / module uses this information, and since this module connects to the internet it uses a weather forecast to adjust watering times. We have seen the run times decreased and increased from the point based upon rain and the temperature. This little module and app have made it quite easy to see how the irrigation system is working, and providing ability to make changes. The app has a simple interface, and is not complicated.

This wi-fi adapter works great. Just plug it in, install the app on your phone and connect. Now I can control my sprinkler from anywhere in the world. Only negative is the app takes a minute to connect to the Rain Bird controller. I can’t say the app is great, but it works good enough.

Modulo che consente il controllo e la programmazione dell'impianto di irrigazione da remoto.

I do like it,

Worked perfectly ! Absolutely loved this control for my irrigation!

Muy buen producto y servicio por parte del vendedor. Me llego en tiempo y forma el módulo, aun que durante la actualización se quedó trabado (parece que fue una baja de señal en el Wifi pero al final el vendedor me estuvo ayudando a realizar pruebas, se diagnosticó con el experto de Rain Bird y se pudo hacer efectiva la garantía y recibir un nuevo módulo. Recomiendo mucho estos productos y al vendedor.

Cumpre o que promete! Mas precisa de um sinal de WiFi bem forte
