Font size/ dark mode

Kirk Davis
Updated at 2025-06-28 04:53:19 UTC 
Dark mode and font size (especially a problem with charts) are two things that were going to be addressed a few years ago. Could I please get a current status on when dark mode will be available and when font size, or at least the ability to zoom the app screen will be available? Turning on the Apple magnifier, or having to take a screenshot and then zoom that so that you can read data is very inconvenient.

Multiple controllers — 1 app?

Jordan B
Updated at 2025-06-28 07:48:22 UTC 
We have 3 controllers for over 24 zones. 

The challenge we’re having is that smart watering isn’t aware of what each controller is doing, so each controller winds up scheduling zones which all run at the same time. 

This is a problem due to the zones being starved for water pressure. 

Is there any way for the app to se all 3 of our controllers as 1 unified home/water supply?

Unified controllers

Gianluca Spada
Updated at 2025-06-29 20:59:51 UTC 
It would be great if for someone like me there would be an option that unifies multiple controllers into just one home so that scheduling would be much easier and avoids multiple zones of different controllers run at the same time. When programming controllers in fact, I have to keep switching programming in various controllers to see if that time is not taken by another zone of another controller. Otherwise water pressure would be a problem if two or more zone are running at the same time in different controllers. 

I hope the message is clear and I hope it will be implemented in a future release as I don’t think it would be that difficult to create. 

Thank you!

When pausing a zone for any reason during watering cycle, the zone is skipped. Is there any way to pause it then resume the watering cycle in the zone that was paused?

Problem: Spark 8 controller stuck on "in communication"

Stefano F
Updated at 2025-08-10 07:01:41 UTC 
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

Scheduled programs not completed

Kyle Giacomini
Updated at 2025-08-10 00:01:57 UTC 
I have some scheduled zones using programs and I'm seeing that the zones later in the program are being cancelled and not completing the scheduled program. What is causing the schedule to be overridden? It's a problem because those zones that are being skipped are not being watered at all.

App reports off-line, controller is on-line and web based app is on-line

Jorge Rodrigues
Updated at 2025-08-08 18:46:45 UTC 

Hello,


I have a strange situation:

- App reports controller as off-line, sometimes it reports on-line for brief periods. It was working fine till three days ago

- Controller has green light

- Web app on the netro site reports on-line and works

- The controller is watering

- The Wifi near the controller is working and I have not changed the password or settings

- I have tried forcing it to change the wifi, I get the bluetooth light and the controller is detected on the app via bluetooth, however it fails after I insert the password for the wifi. This is odd since the device is connected.

I suspect there is a synch issue between the App and your servers. Help would be appreciated.

Interpretation of soil moisture readings by Whisperer

Missy Bartell
Updated at 2025-07-26 12:13:30 UTC 
Topic: General
I have two Whisperers that I move around to various parts of my graden to get comparative readings of sunlight and soil moisture.  I really do not know how to interpret the moisture readings which generally range from 50% to 98% but can be as low as 30%.  Soil type varies from a clayey loam to heavy clay.   How do I know when watering is required?  Does the meter measure the capillary water?  The adhered water?  The percentage of voids filled with water?  How does Netro calculate the percentage of water and what do the readings mean?

Watering time

I added the Netro whisperer 2 soil sensor to my ficus pot. The sensor gives me contradictory messages. It says that next watering should be in one week but every night it sends a notification to 'water the ficus sensor's. What should I do?

Spark not working – won’t start valves despite all attempts

Stefano
Updated at 2025-07-23 06:55:23 UTC 

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

Issue with Netro Spark

Fabrice GOUFFRAN
Updated at 2025-07-23 06:34:33 UTC 

Hello,


Since a few days my Netro is not receiving data from the different Whisperers connected and all of them are well connected to Wi Fi and charged. I am not able to run manual watering, only the planned ones go. It looks like there is an issue or with my Netro Spark or with the Netro Server. I am based in Italy. Please let me know. Thank you.

Why can’t I change my zone off whipsper

Andrew Woods
Updated at 2025-07-22 19:30:55 UTC 
My whisper smart sensor is contacted to my garden plants zone at my holiday home. The smart schedule is not working.this is due to the fact that the sensor battery says it needs charging. Obviously I can’t charge it as I am not there. But I can’t seem to find a way of disconnecting the sensor from the program and on to smart schedule

Problem: Spark 8 controller stuck on “in communication” when activating valves

Stefano
Updated at 2025-07-21 21:17:23 UTC 

Hi everyone,

my Netro Spark 8 controller connects correctly to Wi-Fi and shows as online in the app. However, when I try to start irrigation manually from the app, it just stays on “in communication” and nothing happens.


I’ve already tried:


  • Using a different Wi-Fi network (even a mobile hotspot)
  • Replacing the controller with a new Spark 8
  • Restarting both the app and the device



If I activate the valves directly from the controller, they work fine — so it’s not a hardware issue.


Any suggestions on how to solve this?

Thanks in advance!

My whisperer used outdoor gave me an alert here thru the Netro app saying it has 19% battery remaining. What does it mean? Is the solar no longer working? Is there another way to recharge it or can the rechargeable battery be replaced?
