Hi everyone,

I’ve been using a Netro Spark (8-zone model) for some time, but recently it stopped working properly.

The controller connects to Wi-Fi and appears online in the app, but when I try to start any valve (manually or via schedule), it says “communicating” and nothing happens.

Here’s what I’ve already tried:

• Restarted the Spark multiple times
• Performed a full reset (12 seconds on RST button)
• Re-added the device in the app
• Tried to trigger irrigation manually from both the app and the controller
• Confirmed that the system works when I open the valves manually from the controller
• Tried different power supplies
• Connected to a mobile hotspot instead of my home Wi-Fi (same result)
• Updated the firmware to the latest version (v3.3.0)
• Purchased a brand new Spark controller and tested it — same exact issue

At this point, it looks like the issue is not hardware or network-related.

Could it be a firmware bug or a server-side problem?

Any help would be greatly appreciated!

Thanks in advance,

Stefano Mauri
