Problem: Spark 8 controller stuck on "in communication"

Hi everyone,

I'm experiencing a serious issue with my Netro Spark 8 controller. It connects correctly to Wi-Fi and appears online in the app, but when I try to start irrigation manually, the app just stays on "in communication" and nothing happens.

Here’s what I’ve already tried:

- Restarting both the app and the device  
- Using a different Wi-Fi network, including a mobile hotspot  

Despite these attempts, the problem persists. I also tested the solenoids with a multimeter, and they’re working correctly. If I activate the valves directly from the controller, they respond as expected—so it’s clearly not a hardware issue.

I should also mention that I previously had the same problem with two Sprite6 controllers. That’s why I switched to the Spark 8, hoping it would solve the issue. Unfortunately, it hasn’t.

To make matters worse, scheduled programs aren’t working either.

This is an urgent situation because my plants are currently without water. I’d really appreciate any help or suggestions to resolve this.

Thanks in advance,  
Stefano

Hi Stefano,


We have checked and found that this is a connection issue caused by the Vodafone network. We will send you an upgrade file via email, and the issue should be resolved after the upgrade.

Hi, it's the same to me. I receive "in communication" and valve stay switched off. I tried with home fiber of another home and it works, by the way with 4G router enad vodafone or HoMobile doesn't work. Can you post the workaround? Really thank you
