Orbit 90204Z B-hyve Gen 2 Smart WiFi Hose Watering Timer with Hub - Automatic Sprinkler Controller for Lawn, Garden & Outdoor Plants

At this point I have two of the Orbit 24634 B-hyve XD 4-Port Smart Hose Watering Timers and one of the Orbit 21027 B-hyve Gen 2 Wi-Fi Hubs.I only recommend this if you plan to use your phone (I have an iPhone) to control things. It can be hand programmed, but I would not suggest doing it that way except to initially set the clock (that must be done at the unit).A good place to understand how to set things up and see how it functions can be found here on YouTube. Unfortunately, links are not allowed, but try googling “Orbit B-Hyve XD Smart WiFi Water (Hose) Timer - Unboxing, Configuring, and Review”You do not need to buy the hub to control the watering timers. They will work fine with Bluetooth. However, Bluetooth has a limited range. If you want to be able to control the watering timers wherever your local WIFI network exists or even remotely when you are on WIFI (like on vacation) you will want the Gen 2 hub – you only need one. It was nice getting watering notices when I was recently out of town.The hub should be located where it can reach all your water timers with Bluetooth (I would say 10-20 feet – 10 ft if you are going thru brick façade, etc.). It only works at 2.4 GHz.Start with programing each of the Zones (see you tube video above). Since I have two water timers I gave them different names so I can tell which is which. When you have things programmed (I have a program for each Zone on each watering timer) then play with the app. There are a lot of options and the easiest way to figure things out is to try all the options.Store this thing inside where it is warm for the winter (before the first freeze). Getting all the water out is hard and things can freeze in the garage. If it freezes most likely will stop working due to damage.Big plus is the unit seems to be water tight. In particular, the battery pack has an O-ring to seal water out. The water timers run on only 2 AA batteries. The WIFI hub plugs into the wall. If things are powered down, you will need to add them back to your phone app (for example moving the WIFI hub location).I have only had this equipment for about two weeks so I am not sure what happens when you pull the batteries. Hopefully there is static memory so when you put new batteries in you don’t need to reprogram it, but I would suspect it needs to be reconnected to the phone app.
