The dark sky android app is not available in Canada  so I wonder how accurate their weather is here.  To try and determine this for myself, I looked at the netro temperature graph..  Today it is 34C at my house  but the temperature summary graph in  Netro says it is only 22C. (for my friends still using Fahrenheit that is about a 24F difference )  Does anyone know when Netro gets the temperature that it uses in the graph? Other thoughts on dark sky accuracy in Canada? 

 

I have 4 zones. Two of these cover the same piece of ground. One zone has pgm sprayers and the other zone has regular sprayers .But they cover exactly the same area. How do I tell the app this so that it knows that running the sprinklers for one zone waters the same trees and grass as the other zone? 

To try and clarify the question - these zones cover the same physical piece of ground, (they overlap 100%) but netro doesn't know that, so it will water one zone and think the other zone is still in need of watering - and thus water the same grass twice. (each zone once so the same grass twice).  Netro's algorithm for determining soil moisture levels can't work if it doesn't realize these two zones are the same physical piece of grass. 

app does not run on iOS 11 iPhone 7 

Any ideas 

In the zone settings, the app offers different types of watering, for example, regular, deep watering, boost, etc. One is labeled EPA. 

What are the differences between the settings and watering times/amounts for: regular, boost, and EPA?

Hello - I have a 9 zone system. I have set all of the zones with the exact same settings for type, grass, etc. I do not have any sensors. 

However, the app shows the zones having different moisture levels, and waters certain zones differently than others, even though the settings and system location are the exact same. 

Can you help me understand why the system would treat these identically programmed zones differently

Thanks!

Hi just wanted to know if I running only customs programs for watering I can take advantage of the Smart Watering feature. In other words, I only have my own watering program, NO smart programs, and need to know if the controller will skip these programs when raining. If NOT will the sensor allow provide that feature?

Thx - Mike

I have had the netro for a  week and it has yet to water the lawn. Today, it states 12 more days until the next water. I have Bermuda grass in Alabama, it is 90+ degrees daily. Seems like it will never water. It has only rained for 5 minutes the last week, but the app thinks it has rained more often.

is there an option to set up and kick off a manual ad-hoc run without having to schedule it?

I have eight zones with smart watering enabled for all zones. I noticed this morning when looking at scheduling that a few of the zones will water multiple times in the same morning. For example, Zone one will water for 4 minutes, Zone 2, Zone 3 excetera. Then it goes back to Zone 1 for 3 minutes, and maybe zone for for 7 minutes. Is this normal?

I have inserted a screen shot.Notice the zone, "house left."

i’ve had the controller installed for almost 2months now and it works fine. I like the idea that it seems to know how much to water and keep the lawn  green. However I have pets who use the backyard and would like the watering to be between 9 pm and 5 am.  I think the system can be setup for manual watering times BUT that defeats getting an expensive smart system to replace a low end rainbird system.  

Is there anyway to set up time constraints on the system and still run on automatic,

Also lack of a manual and good instruction is a pain. 

I have a system working in Florida and I just wanted to do the same thing in Kansas and I bought it and I have wired it but I haven't plugged it in because I don't know how I'm going to control each different location and I'm afraid something might go wrong and I won't be able to water in Florida.

So how do I control each separate location with the same phone?

The app has a number of soil choices- I don’t know which to choose. I assume different soil has different water retention. Is there a list which shows how much water the different soil types require?  Or is there a way to tell which soil you have?

How is the subsoil moisture determined on the Netro App for each zone?

Smart watering disables my program as it thinks its going to rain, how do I override it - if the weather forecast doesnt pan out or we dont get enuf rain

This is a great product with a great application as well. Thanks to the team and the developers for working hard to make this right. This is fantastic!

Not really a question but a shout-out about the changes to the app.  l found the wonderful new additions that the Netro team just made.  I suggest everyone check out the new additions.  I have tweked a couple of my zones and Very pleased.  Suggest everyone check it out!

Why should we conserve water? Water is under threat from many sides. It faces pollution problems, outdated infrastructure, rising costs, and unprecedented droughts and rainfall patterns as the climate changes. Only 1% of the entire water supply in the world is available for human and animal use. 97% is salt water and the remaining 2% are in forms of ice caps or glaciers. People all over the world use this 1% for agriculture, manufacturing, community and personal household needs, and for sanitation operations.

Nowadays drought conditions occur everywhere. There's been a lot of news and talk about the drought condition we're having and saving water. Depending on climate conditions, California, Texas, Nevada and many other states have strict rules about when and how much water is allowed for home irrigation. States and cities are forced to implement mandatory water conservation programs. However, Netro honors your local watering regulations if exact location is provided and will inform you when restrictions apply. With Netro, you will not need to worry about fees and penalties. Netro will automatically upload your local water conservation regulations to your controller and cut down your water usage based on these requirements. You can go to Settings->Regulations to see your local water restrictions.

You still pay for each drop of water in your home, whether you use it or not. By using water wisely and eliminating leaks, the extra water you save means money in your pocket. To conserve our water, we should be watching our water usage to prepare for future drought.

The amount and frequency of watering depends on the root system of your plants. Shrubs and trees -known as woody plants - have the potential to grow deeper root systems than flowers which means they draw water from a larger volume of soil. In general, if you receive a good rain every week or 10 days, these woody plants are probably getting the water they need. They thrive with a deep watering with less frequency than most flowers. When plants are shallow-rooted they will need more frequent light irrigation just like the lawn.

1.How to Water Shrubs

The most efficient way to water woody shrubs is to apply water slowly to the soil allowing it to penetrate deeply to rewet the entire root system without running off. This can be done by repeatedly moving a slow flowing hose from bed to bed or by using a drip irrigation system that allows water to leak gradually along the entire length of the irrigation tubing. It is important that the water reaches the plants roots. It is unnecessary and wasteful to water deeper than the plant's root zone.

If you are using an irrigation system, it is worth noting that woody shrubs need to be watered separately from shallow rooted plants and thus need to be on a different irrigation valve than lawns or flowers.

2.How to Water Trees

Trees need regular water during the first several years after planting, until the roots have grown deep enough to carry the plant through dry periods. Once established, however, most trees require only infrequent irrigation.

Stop watering when runoff starts. Soils high in clay accept water slowly, often as little as 1/4 inch per hour. Water infiltration is especially slow in compacted soils. If water starts to pool or run off, stop irrigating, let the water soak in, and start watering again.

Don't saturate the soil for long periods. Water displaces air in the soil, so long periods of soil saturation can suffocate growing roots. Take a long enough break between irrigation cycles to allow the free water to be absorbed. If in doubt, probe or dig to make sure that the soil isn't soggy below the surface.

3. How to Determine the Right Amount of Water

Don't wait for the plants to tell you with wilting and leaves dropping off. Then you’ll just be watering to keep the plant’s roots alive so it may possible come back later. Inspect the soil. Dig around with your hands, soil probe, garden trowel, or shovel. You’ll be able to tell quickly how far down you are actually watering.

With a little practice, you will be able to maintain the proper moisture balance to ensure your shrubs get the water they need to thrive in your landscape.

Watering correctly saves time, money, and plants. The heat of summer is coming, and along with it, water restrictions in many municipalities. Summer water restrictions can force us to re-evaluate our watering practices. In many cases we may find that our watering practices are wasteful and inefficient.

Deep, infrequent watering is recommended. In most cases, an inch of water per week (rain plus irrigation) should be sufficient. Applying that inch of water in one deep watering will encourage deeper rooting, which leads to stronger, healthier plants. Watering once a week also fits well into most municipal water restrictions. Shallow, frequent watering, on the other hand, will lead to shallow root systems and high water loss through evaporation. With shallow watering, such as light frequent sprinkling, you actually end up wasting quite a bit of water and still don’t meet the needs of your plants.

The best time of day to water a garden is in the morning, since that gives the plants time to dry off before nightfall. It's cooler and winds tend to be calmer so water can soak into the soil and be absorbed by the grass roots before it can evaporate.Leaving water on plants overnight can lead to mold. Watering your garden at the right time and using the right method will keep your plants healthy.

There may be need to evaluate the device used for watering. While a lawn sprinkler may be a good method for the lawn, it may not be the best way to water a vegetable garden. Pick a watering device that matches the needs of your garden and the time you have available to water. Once a device is selected, know the correct way to use that device, in order to water efficiently.

When faced with summer watering restrictions, save yourself time and money by carefully selecting the time and watering device which best suit your garden’s needs. With Netro's smart watering, home gardeners may not fear that with restrictions in place they won't be able to properly water their gardens. Netro specializes in Evapotranspiration Reduction (ETR) and automatically make seasonal watering adjustments. Even in the hottest summer, Netro takes good care of your garden.

If you must water in the evening, try between 4 and 6 p.m. which should give the grass blades time to dry before nightfall. The later you water, the greater chance of disease becoming prevalent in your lawn. It's worth noting, though, that you don't necessarily have to water your lawn. Lawns are resilient. Established and properly cared-for lawns can survive weeks without water by going dormant (when the lawn turns brown), then recover once the rain returns.

Frequent, shallow watering encourages a shallow root system. A shallow root system means a lawn is under drought stress when the top inch of soil dries out.

Conversely, deep, infrequent watering during hot, dry weather is important to maintain a healthy lawn. Deep watering encourages the turf to develop a deeper, more extensive root system. The denser root system will make your grass less susceptible to periods of drought. A more dynamic root system will also offer the fringe benefit of discouraging competition from weeds.

To determine how long you have to run your sprinkler or irrigation system, take a flat-bottomed container such as a coffee can and mark off half-inch increments. Place the can or cans where it will be hit by the water, and time how long it takes to gather a half-inch of water. Then run your sprinkler twice as long. You may need to apply water even slower to steep slopes to avoid wasting water to runoff.

Netro's motto when it comes to watering: slowly, deeply, infrequently. Netro's algorithm is based on expert gardening knowledge, one of which is to avoid watering equally everyday and instead to water less frequently but deeply. Netro waters your garden only when the soil is dry enough in order to draw more oxygen into the roots, leading to a lusher landscape. By default, we allow the moisture level to deplete to a lower level before next watering and that is why you might see longer watering duration than the original settings on your old controller.

Netro smart controller gives your lawn the right amount of water, assures that your garden is getting its required amount of water – no more, and no less.
