My LED is dead/won’t come on, but my unit works fine. Verify it works properly is my suggestion. I don’t necessarily need a light. :)

I noticed my “time” doesn’t match: I set my watering to go from 0800-0815. The unit waters from 0803-0818. So it may seem like it didn’t shut off at the right “time”, but it is watering for the correct amount. 

Are they close enough to the router?  Do you get good WiFi signal where they are?

I had to get a WiFi extender for my Pixie to work, and it’s right outside my house. I plugged an extender into the shared wall, connected it to my router (make sure your extender requires a password), and now everything is working properly. It even made cell phone coverage in my house go up (WiFi calling)

Let me know if you have questions. I don’t want to seem like I’m selling a certain brand extender, which is why I didn’t tell you what I used. :)
