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?

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

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.

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 

Cómo puedo hacer que el programador riegue más de 60 minutos. Solo me permite 60 minutos por programa

Please help. I'll provide a reward for getting my N-12 to work.

Assumption is that rain events need to prevent / skip watering.

I have one requirement that is the opposite where if it has rained more than 5mm, i want to use my watering system to pump water for about 15 minutes from my 100,000 litre water tank to a 12,000 litre holding tank that I use for gravity fed gardens. 

Is there a way?

I have tried to access my whisperer plants sensors, but they do not show up in the Netro app. What do I need to do to rectify this?

The door came off my spark 8 unit.  This made the electronics tape disengage from the base. How do I reattach that tape back into the slot.  I tried by hand but it seems impossible without detaching the motherboard and making more problems 

I was offered a discount on January 24, 2025 on purchasing a New Netro Sprite 6 after mine failed.  I cannot get anyone to respond to my email.  I would like to proceed with the purchase.

Thanks,

We are using your API example, where ABCDEFG is the device key.
Using this example, we're getting the following error returned: {"status":"ERROR","meta":{"time":"2025-01-23T10:15:30","tid":"1737627330_uXNP","version":"1.0","token_limit":2000,"token_remaining":1993,"last_active":"2025-01-23T10:15:30","token_reset":"2025-01-24T00:00:00"},"errors":[{"code":4,"message":"Invalid sensor","params":{}}]}, 

It is the same when we use the actual device keys for our Sprite and Whisperers 2.

Could you please help understanding why we're getting the error number 4 "invalid sensor"?

As previous question, netro showing offline, but green on box. Not watering.

Have reset network and reconnected. Same.

Suggestions?

Hard reset?

I don’t know what’s going on my Netro spark randomly started on its own at night. 5 or 6 times a night for 1 min up to 10 min. Yesterday it ranned for nearly 90 minutes. How can I prevent this?  

One of the sensors started giving humidities form 80 yo 30% from one hour to another. I changed the position of the sensor and restarted various times. Now the sensor measures 0% humidity. 

Now after 4 days the sensor is dead. Tried charging and still doesn't start or show any life.

Any ideas to solve this problem?

Regards. 

Hi,

I've just installed a Spark 16 and I'm playing with the settings. I tried out a zone photo that hasn't really worked but can't seem to find a way to delete it.

Can someone help please?

Hi.

My controller operates but many times, rather than executing the time setting. It just cuts out? 

I do have a sensor connected but I took it out of the ground to exclude wet soil feedback 

I'm guessing there is a parameter forcing the stops? 

Could anyone give me a direction where to look? 

Thanks 

This morning my 16 zone Spark unit was showing a red LED.

The app said it was online but when I tried to manually water a zone, it just said "connecting" for the duration with nothing happening outside.

Our wifi was running as normal and the room with the controller in had a good signal.

Unplugging and plugging back in solved the problem but it doesn't leave me with much confidence of the unit if it's going to do this at a critical time of year without being noticed.

Is there a reliability issue with the latest firmware?
