Doubts about installation and required devices

I would like to know how to manage the following garden.
I currently have 5 areas of lawn and other plants, with 3 Hunter PGP sprinklers for each area. Of these 5 zones, there are two with a lot of shade, and the rest are sunny (central Spain).
On the other hand, I have another zone with 6 diffusers, and a last one with a drip system for the Leylandy hedge.
I am interested in acquiring a Spark programmer but... how many Whisperer would I need?

How does Spark differentiate between the different zones and how does it combine the amount of humidity needed? The type of grass I have is made up of Raygrass, Fescue, Poa, and Agrostis. I could send you a plan of my system for your advice.


the outer lines indicate the individual irrigation fields.
AREAS A1 - A2 -A3 - A4 -B1 and B4 are the shadiest areas.
These areas are shadier due to the height of the hedge.

For orientation, a straight line between points 13 and 8 marks the North-South line, where 13 is South and 8 is North.
Neither the diffuser area nor the drip line of the hedge is represented here.
The water inlet is located in the legend E1, between sprinklers 12 and 13.


Thank you very much.

Dear Juan, 


Spark-8 supports upto 8 zones (similar Spark-16 supports 16 zones). For each zone, you can customized the sprinkler type, soil type, plant type, etc.  For your case, you have 6 zones, with 3 or more sprinkler heads in each zone. So Spark-8 should be enough. 


The whisperer sensor is optimal. It helps to get your soil moisture data more accurate than estimation. However, without the sensor, the Spark can work as well. It's recommended to place one sensor in each zone, however, you can share the data to upto 3 zones if these zones have similar settings (plant, soil, sprinkler, etc.).

thank you very much,
How is each sensor associated with each irrigation zone?
Is it possible to tell the system in which zone each of the sensors is located so that it has a record of the sprinklers or set of sprinklers that affect it?

Thanks again

In the Netro APP, you can pair the sensor with a zone. We don't need to know the exact location of sensor. Please place the sensor in a typical place of the zone, e.g. in the middle of the zone. Please don't place it in corners, dry spots, etc.

On the other hand, in the we I only see for EU Spark 16, I don't see spark 8.
is there a price difference?

Hi Juan,

Currently we only sell EU spark 16 and we will launch spark 8 in the future.

Thanks,
