Review: Love 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.
Review: An Incredible Upgrade To Our New Rain Bird Controller! - 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.
