  • Easy installaion and programing
Size: 8-Station Style: Indoor Pattern Name: Timer
I purchased this to replace a manual Rainbird controller. The wifi feature and phone app allow for the program of the unit without any physical contact. The unit will also monitor the weather by using your zip code to modify the watering schedule. It is very easy to adjust watering time by the day and zone, as well as run a manual watering. Before ordering, insure you have at least two bars in a wifi signal, where you plan to mount the device. This is to make sure the device has good contact with your router. The installation instructions are very clear and easy to follow. ... show more

  • Excellent controller!
Size: 8-Station Style: Indoor Pattern Name: Timer
Great controller! Quick & easy to install to replace an old model that stopped working. Easy to program, by either the controller or the app. App easy to install, program and adjust as needed. Has worked great since installed. Our irrigation pros were impressed by this model.

  • The BEST watering system!

The PERFECT companion to any dedicated gardener! I love that I can add multiple times to my watering schedule or even a quick watering directly from my phone wherever I am. It was super easy to install and program - I would highly recommend this unit to anyone!

  • Needs additional common terminals. Terminals are very small and difficult to connect wire.
Size: 8-Station Style: Indoor Pattern Name: Timer
Works well and easily connected to my home network. Only issue is there is only one common connection terminal post. Terminals are very small in size. T he controller should have additional common terminals. I currently have four valves that operate four zones using four separate wire cables due to the locations of the valves. The common terminal will allow 2 wires to connect but any more will not attach securely. To fix this, I purchased an electrical panel grounding bar and mounted it below this controller. I connect all 4 of my common wires to the ground bar and then run a single wire to the common terminal on this controller. The other valve wire connect as usual. ... show more

  • Definitely don't buy this for the app....
Size: 8-Station Style: Indoor Pattern Name: Timer
I bought this to replace a mechanical Rain Bird timer that is significantly older than I am. I had to do a lot of work on my system (replacing valves, digging out heads, fixing leaks, etc.) and I was looking forward to being able to control it from my phone so I didn't have to walk back to the garage whenever I needed to start or stop it. Unfortunately it has not lived up to my expectations. It has been a couple weeks now since I got it installed and I am finally annoyed enough to come share my experience with all of you. Since I didn't get it installed for a few weeks after I received it I am now past the return window, otherwise I would be doing that right now rather than writing this. As it is, I must deal with Rain Bird's customer service. I will update this review as that plays out. Here are the problems that I will be bringing up with their customer service. 1. The biggest problem is that the programmed run times don't work. I have zones 1-5 set to run sequentially, and the app shows that on the schedule. Only zone 2 has been running though, zones 1 and 3-5 haven't run at all. All zones work fine if I run them manually, but only zone 2 runs automatically. 2. The controller will not connect properly to my network. With some work it will connect to my main router, but that is on the far side of the house and the signal is very weak. I have a range extender that is much closer, but it will not connect to that no matter what I do. Every other device I own has played nice with the extender, but no such luck here. It is possible that the resulting weak signal is the cause of some of my other complaints. 3. The controller is connected to the pump start relay for my well, and it turns it off for a fraction of a second between each zone. I am no expert, but that can't be good for the pump. I was hoping it would have an option to start one zone several seconds before stopping the previous one. Boy were my expectations too high. 4. The app is bad. They clearly didn't put much effort into it. It has the look and feel of the app for the made in China smart outlets I bought for $2.50 each. Each time I select anything it takes 10-30 seconds for it to talk to the controller first and then half the time it just gives me a communication error. When I do a manual run it is a gamble whether it will start in 5 seconds, 5 minutes, or not at all. This is a big disappointment, as the app was the primary reason I bought a new controller in the first place. 5. Finally, their tech support. The reason I am writing this BEFORE contacting their tech support is because they don't have an email address, I have to call. Between 7am and 5pm. Guess what I am doing between 7am and 5pm. Get a tech support email address guys. Making your customers take off work early to call you about a problem they are already unhappy about is not a recipe for success. ... show more
