App is glitchy

The app has quite a few bugs:

The main page tells me 0 zones watered but it just watered them.

Notifications won’t tell me which zones it watered just says “watered 0 zones” several times in a list. I want it to tell me which zones were watered, for how long, and at what times.

Also the calendar view is nice but I’d like more control. Tell me what time each zone is going to water and allow me to deselect certain watering sessions not the whole zone for the whole day. I suspect that the soak cycles are causing some the bugs in this section.

Also the soak cycles are confusing. I think the calendar view/controls that I recommended will help clarify.

Please keep making app improvements for us, I’ll stay a loyal customer if I can see developer responses and app updates that fix problems.

Another product hits market before it's ready

So I spent the $$ on this thing and even bought a moisture sensor- all with dreams of beautiful green grass, tall happy trees, and maybe some plump tomatoes but all I got was this lousy headache.
First off allow me to mention I am no stranger to technology or irrigation controls. I've had several over the years and have eyeballed a wifi setup for some time now and being familiar with the Scotts brand I decided it was time....$175 and 6 days later and I'm looking for the box so I can return it all.
The controller can't see and won't connect to the sensor. The day I brought it home I was able to connect and set some zones up but 5 days later I changed my router out-went to update the controller and 1.5 hours later it can't even see me now. Says I'm too far away but I'm standing right next to it. Any closer and it's inside me.
Its not a huge surprise however because when I was able to use it, the app seemed to show pages overlaying pages and some features wouldn't work. This very much seemed unfinished and certainly unpolished.
I'm still sold on the concept but I obviously chose the wrong brand. If this doesn't start connecting tmrw ill return the whole mess and get a proper system.

Switching from Blossom to Gro Connect is an upgrade so far

So I’ve owned a Blossom controller for a year and had some quirky behavior which I hadn’t figured out whether it was too aggressive with the water sense, or whether there were some other issues with my system, but basically I wasn’t watering enough. Over the weekend I downloaded and connected to my Blossom using the Gro Connect app. The UI of the app is quite different, but so far it seems to have added some additional features and settings. When viewing an individual zone there is a button to tap to test the zone - this seems to be a 1 minute cycle. Very handy! When setting up the water sense there seems to be 3 or 4 more options that will allow me to fine tune the settings - things like root depth and inches per hour that the sprinklers put out in each zone. Also the schedule tells me what it’s planning to do each day. I’ll keep a closer eye on that this year to see if it really does increase watering to cope with the long hot sunny Kansas summer.
