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

Netro Sprite 2.5.3 no watering and no reset

AMC
Updated at 2021-02-18 13:04:06 UTC 

hello,


I installed my nero sprite-12 2 months ago. Today , finally, I connected my 6 valves and the C cable to the Nero. Then, I tried to watering the first one (doing play bottom) but the valve does not work. I put 24v int he valve directl and it started watering. Then, I check with a multimeter the output for the valve in the nero controller and It was 0v.


Then, I delet the controller in the app and tried to reset the Nero sprit but I doesnt do anything. I hold the rst button during 8 or more second  several times but the led stills keep lighting and no wifi radiated to connect. 


¿How Can I solve this issue?

Is it possible to name zones for easier identification

Chris Graham
Updated at 2020-05-24 20:37:39 UTC 

I'm evaluating whether to by a Netro and one of the things I need is to be able to name zones rather than have a zone called say "Zone 6".

I don't see any users manual on your site to answer questions like this.

Rearranging zones?

Kurt H
Updated at 2020-05-23 19:17:20 UTC 

I do enjoy my Netro, and the app makes things pretty handy.  I do have a couple of questions.


Are there any plans to allow the software to rearrange the zones in a watering cycle (or is that already available and I am just missing it?)  Right now it seems I am stuck watering in the order I have wired the controller.  It would be nice to water one zone, let that soak in while watering another zone, then come back and water a third zone that is adjacent to the first zone.


Another question I have is - is it possible to copy a schedule so that I do not have to set each of the 5 zones for every schedule.  There are times when I would like to run a one time schedule that follows my normal dry schedule,  or follows my moister schedule.

Using measured flow rated instead of estimated

Wayne Richards
Updated at 2020-05-23 16:07:26 UTC 
I understand that Netro estimates water usage based on time, emitter type,  and square footage,  but I  have access to actual flow rate via a Flume flow rate monitor. Is there a way to replace the flow rate estimates with actual rates for each system?

Do not water when it rains or rain is expected

Kobus Marneweck
Updated at 2020-05-19 03:33:33 UTC 
I replaced my Rainmachine with a Netro but I cannot configure it to do what the Rainmachine did. I live in Austin And can only water 1 day a week. Water is incredible expensive so I  cannot use Smarzone because my water bill will be too high. I want to run each zone for 20 min once per week and not water when rain is expected or it is raining. Netro does seem to be able to do this. Any suggestions?

Watering program

Maciej Karpinski
Updated at 2020-05-18 01:01:57 UTC 

Hi there,


I recently installed the Pixie, and have set up both the smart feature and a regular watering program. The watering program was supposed to go off this evening, but it didn’t. I then checked in the schedule, and all I saw were any restrictions and the smart watering schedule. My program was not there. I set the filters to show me the enables program, but it still does not appear. I have no way of telling with the program has been initialized. Is this a glitch? Should the program appear on the schedule? Why did it not activate when it was supposed to?


Thanks.

Yves Desrosiers
Updated at 2020-05-17 18:31:27 UTC 

Hi

Had to replace a solenoid on the valve on one of my 2 zones and when I do a manual 5min watering on zones 1 or 2 none of them start. I can hear the click of the main valve opening but none  of the zone 1 or 2 valves is opening...if I use the override on the valve to open manually, the water does pass...seem the controller is not sending any open command to eather solenoid of zone 1 or 2 ..

Thanks for your help :)

Program set for 20 minutes per zone but watered for only 5 min

EASTBOBDAM D
Updated at 2020-05-17 13:18:19 UTC 

Hello All, I have three zones and created a program to do a deep water for 20 min. Starting from 5AM and ending at 6AM which is expected to run every 3 days. This morning was the first time I ran it and noticed on my home screen it said watered for 5 min. Any reason why this changed? I'm thinking smart watering has to do with this? If so, I'd like to try and keep this feature for the rain aspect (not to run when it will rain). I read if you disable smart watering (which I can't find this feature anymore), then it will still run the  program when it rains,anyway if I'm in the right ballpark to have your cake and eat it too. 


Thanks in advance

No 2.4GHz wifi

Carlos Oliveira
Updated at 2020-05-16 11:29:24 UTC 

Hi,


My netro has been working fine for the past many months.


Suddenly it stopped working and light blinks.

I try to configure the Wifi again and it states 



I am sure my 2.4 GHz network is available there as I have 2 other devices 10 Cm away from the netro and are working fine at 2.4GHz

I can confirm that in my Orbi Router.


Any ideas ?


Thank you

Carlos

Default rain settings

What is the default setting for not watering the day before and after a rain day? I think it was to skip the day before and of, but not the day after (wish I could reset defaults). Why is the default what it is?


Also, why is the rain delay trigger 0.2? What would happen if I changed it to 0.1?
