Hunter BTT 2-Zone Tap Timer Gray

I'll tell you, the first time you start and stop your sprinklers from inside your house using your phone is a real kick.I decided to try one of these out, because I'm tired of spending the better part of a day moving the hose around the lawn to get good coverage. I started in the back yard, laying hose and putting out 3 Hunter bodies with MP Rotator heads. Then I connected them to this BTT timer, and it works like a charm. Now, I can water at ideal times of day without having to set the alarm clock for crazy time, and when it's time to overseed, it will be very easy to water for 10-15 minutes every morning with zero effort. It's like having a $3000 in ground system installed, but for a small fraction of the cost (although the sprinkler bodies and hoses are above ground - which makes them easier to maintain, so you decide if that is a plus or a minus for you).Bottom line, I'm happy and will be giving my front lawn and side yard the same treatment in the coming weeks, before the hot weather arrives.The app will connect to multiple timers. It also has a fair amount of flexibility for setting your scheduling, though it's not the most intuitive interface ever devised. However, if you are willing to dig through it, it can set a schedule based on days of the week, or on a cycle of days (water every 3 days for example, regardless of what day of the week it is). You can set up multiple run times during the day. You can set it to cycle periodically based on time rather than days (every 3 hours for example). You can also set it to cycle on and off over a defined window of time (run for 15 minutes, stop for 5, repeat, for two hours every morning for example).It rains often where I live (though accumulation is almost never adequate in a week) so this next feature is important: You can suspend the schedule for a selectable number of days. So if we get 1/2" of rain, I can suspend the schedule for 3 days, and it will return to it's normal program afterwards.Of course, you can run this manually, for a selectable period of time. You can also run it manually by physically pressing a button on the timer and it will run for an hour and shutoff automatically. There's probably more capability here, but that's what I've explored so far.A couple nice features in the interface: you can customize the name of each timer and for this model with two outlets, you can customize the name of each outlet (timer=back yard, zone 1=grass, zone 2=shrubs drip) and you can even add pictures to those zones so it's really easy to identify which area you are working with when programming.This does run on two AA batteries. I do not know what the battery life will be like, but after about 5 days running on rechargeables, they are down 2%, so you should have no problem getting a full season out of a set of batteries, especially if you aren't often connecting with the phone to fiddle with them.There are only a few minor things I'd like to see improve in the next generation of this product, or in future app updates:1. I'd like the app to have a more intuitive design that uses a more plain language approach so that anybody can set their timers up without having to figure out what the different options mean.2. I'd love to see a slightly more robust bluetooth transceiver on this. The range is limited. I believe the product says 30', but I lose connection about 20' away, and if I am inside, I need to be within about 10' to connect. I know this is a trade-off between battery life and range, but I'd be happy replacing the batteries every 2 months if I could sit on my recliner and connect to various timers on different sides of my house. Maybe another option would be to offer an accessory hub that plugs in somewhere in the house and can extend the signal reach.Overall, I'd say this is a major improvement over other programmable timers I've used, with more options and easier programming. Being able to suspend scheduling or manually water from inside the house is a godsend.Highly recommended.

Connection is lost if I move further than ~4 feet away. The 30' distance advertising claim is perhaps for more fully-featured cell phones than mine?But the connection's not as bad as the sense of dealing with a app that needs toughening. How long must one wait between saving set up commands? Why does one zone set up seem to delete the other?I've found that when I see that Zone 1 appears to have been set up as wanted, then moving along to program Zone 2, all bets are off. Zone 2 doesn't save a set up that's half an hour later than Zone 1, for example. At another try, the Zone 2 time settings and duration values all turned red, with no way to find out what I'd done wrong. Very rickety user experience. Factory Reset brought no response. I ended up uninstalling and reinstalling the "beta" version from Jan 3, 2020. We'll see if it manages to water both zones, as set up, in two days.Tried turning on Zone 2 manually to make up for it missing a watering. Now, the Zone 2 button on the unit is. apparently going to forever blink red. Nothing I've tried has stopped it. May cause shorter battery life, or just be irritating. This app needs, at least, some FAQ support.I would not wish this app on anyone.

This product does exactly what I needed and the setup and controls couldn't be simpler. It's fantastic and well built. I think the interface on the app is fine and really like the clean appearance of the device itself (it's not covered in buttons). The best feature is the flexibility in programming each zone through the app. The Bluetooth range is a little smaller than I expected (about a 15' to 20' radius), but not a big deal. Maybe on a device this expensive metal threads would have been more appropriate, but the plastic threads have held up well so far (just have to be careful with the hose connections).

I agree with many of the 1 star reviewers that you have to be right on top of the unit for your phone to connect via blue tooth. That being said I'm not sure it really matters whether you are 32 feet or 5 feet from the unit in order to connect. Does that save you about 10 steps? The blue tooth connection doesn't work through walls for me so even though my faucet is just outside my living room window I have to go out and stand in front of the unit to get a connection.I bought this because we went on vacation for a week and we had just planted some bushes that I wanted to be watered heavily during this dry spell we have been experiencing. I had no problem setting the device up and connecting my soaker hoses. Pressure was fine for those hoses. I had people check on the device and it watered the bushes as I programmed with no glitch.I gave this a 3 star review because it really does nothing much more than a manual timer. It is not designed to allow you to change the programming remotely (like you can with a smart device via WIFI). I'm not going anywhere else this summer because of the virus and I imagine that I will be looking for a smart wifi device next summer. I did not see any such device when I bought this 6 weeks ago at least not with high enough review ratings that would encourage me to buy it.

Works well and is reliable. Much easier to set up with Bluetooth. We’ll see how it does after a season or two.
