What is the difference between MIYO and a programmable water timer?

Rather than a timer switch, MIYO watering logic is 100 % geared towards the needs of the plants. You can adjust these easily, for example by inputting moisture level limits and other parameters in the app. And if you use the cloud, you can access your garden watering system from anywhere in the world.

What advantages does MIYO offer?

Batteries not included! Sensors and valves are powered by solar energy, a sustainable that spares you the cost and nuisance of changing batteries.

With a special wireless standard, the sensors, valves and cube can communicate with each other within a free-field range of 350 metres approximately 0,22 miles; based on 868 MHz), meaning you can install MIYO in gardens of any size. So there’s no need to provide an Internet connection to every inch of your garden.

If you’d rather avoid another cloud service that collects your data, MIYO can also be restricted to just your home wifi network. The cube will still draw weather data and updates from the cloud, but no personal data will be transferred from the cube to the cloud.

And all data is stored locally on the cube. So apart from installation, you don’t need an Internet connection and your garden is in the best of hands even if the Internet drops out. You can then connect MIYO with the cloud if you want to access the system worldwide through the app.

MIYO can be installed and set up in minutes, with no lengthy operating instructions. And using the app is so simple, you don’t need to worry about the technology!

The valves are supplied with water in a staggered configuration to avoid problems with water pressure. If required, you can excluded a particular watering area.

MIYO isn’t just a means to an end – its striking design also makes it an attractive feature in any garden.

Is MIYO suitable for watering on balconies and decks as well?

Yes. Wherever there’s a tap and outdoor plants to water, MIYO is ideal.

Can I use MIYO inside the house as well?

No, MIYO isn’t designed for that. Please only use MIYO outdoors.

What does ``watering area`` mean?

Different areas in a garden (e.g.: shaded lawn, sunny lawn, flowers, raised beds, hedges, etc.) require different amounts of water and have to be watered at different times.

At least one valve is required for each watering area, which can only use one sensor. Depending on the available water pressure (tap water, ground water pump, well), only a certain surface area will be watered.

How many sensors and valves do I need for my garden, and what’s the maximum size?

With one cube you can divide your garden into multiple watering areas. At least one valve is required for each watering area, which can only use one sensor. Ideally, you would always have the same number of sensors and valves. A single cube can connect to more than 200 devices.

It makes no difference if the garden is 50m² or 500m². Decisive factors here are the number of watering lines and sufficient water pressure.

How do I put MIYO into operation and where can I get the digital operating instructions?

All information is available under Downloads.

Can I perform the installation myself and how long does it take?

Yes, commissioning is very easy and can be done in a short time. The app and operating instructions will guide you through the individual steps.

What do I need the app for?

To start the MIYO watering system for the first time, to configure the optimal watering settings and as a dashboard for all your smart gardening activities, accessible from anywhere in the world. After the initial set-up, MIYO also works without the app.

Which operating system does my smartphone need for the app?

iOS 10.0 or higher or Android 4.4. or higher.

Where is the best place to install the cube?

Install the cube wherever you have an Internet and power connection. As a rule, the best place is somewhere in the vicinity of your Internet router. To make the most of the wide range of the wireless system, however, the ideal location is somewhere near the garden. Make sure, in any case, that the cube is placed indoors.

Can I use MIYO with any router?

Any commonly available router with Internet access is suitable.

The cloud connection is not established, why?

Please make sure to connect the LAN cable first and power cable afterwards.

Additionally verify that the LAN cable is connected on both sides and your router has an active internet connection.

Last but not least, if cloud connection is disabled on your cube. The connection will not be established and cloud LED is off.

How do I add more sensors and valves?

Simply repeat the steps you followed when setting up the starter kit. Just click on a watering area in the app settings.

Why can I not set the sensor or valve in teach-in mode?

Please check whether you held the magnet in the correct position: in the centre on the top edge of the solar cell of the valve/sensor, as shown in the quick guide.

Also, hold the magnet in this position only for 3 seconds, then remove it again. In the case of contact of over 10 seconds, the connection/configuration is deleted again.

Finally, please use only the magnet enclosed in the packaging, as this works best with regard to size and holding force.

If you have done everything correctly, the LED on the device starts to flash.

Should this not be the case, the device battery may be empty. Place the device in the sun for 30 minutes to charge the battery. Charging does not work through a windowpane.

How does the system ensure that my sensors and valves only communicate with my cube?

Once your MIYO has been programmed, the devices are uniquely assigned to your cube. So there is no risk of mixing up the devices.

How can I distinguish between different sensors and valves that I have installed?

 Each device has a unique address and is therefore uniquely identifiable.

If you click the lamp icon in the ‘Create watering area’ section in the app while carrying out installation (or in the settings for any existing watering area), the LED on the corresponding sensor or valve illuminates briefly.

You can also store a name and an image for each watering area that shows the sensor and valve.

What do the little lights on the cube mean?

The first light (from the left) indicates the power supply. The second light provides information on whether the cube has a radio connection. The third light provides information on whether the cube has an internet connection. If you deactivate the cloud connection in the garden settings of your app, this third light goes out.

Where is the best place to install the sensor?

Choose a spot in the watering area that is as well-lit as possible. The location must not be in a depression and should be representative of the conditions (ground moisture, temperature and brightness) of the watering area. Ensure that the solar surface of the sensor is not covered by leaves and that it gets enough light.

Why do I have to make a small hole for the sensor rather than simply pressing it into the ground?

The electronic component for measuring the ground moisture is located on the lower neck of the sensor, and it is sensitive.

Our experience shows that the sod or soil (e.g. clay soil) can represent a serious obstacle and damage the sensor.

More importantly, to get optimal measurements the sensor surface must not be up against a root or stone or compromised in its function by a small hollow space filled with air or water. You can avoid all of this by digging a small hole.

Dig the hole with a spade or loosen the soil with your hands (see quick instructions). Afterwards, carefully pack the soil again to ensure that the sensor surface has optimal contact with the soil.

Do I need a second account for a second cube?

No, multiple cubes can be assigned to each account and controlled with the same app, e.g. one cube for the balcony and another cube for the allotment garden.

Where can I get hoses, sprinklers and valves and accessories, and what is compatible with MIYO?

Hoses, sprinklers and valves and accessories are available in our web shop. The web shop features REHAU-brand products in colours perfectly coordinated to match with MIYO.

If you already have these accessories, they will be compatible with our standard connectors.

In what languages is the MIYO app available?

The app is currently available in German, English, French and Dutch. The app language depends on the system setting of the smartphone.

How can I connect MIYO with IFTTT?

 A tutorial on this will be released shortly – until then, you can find details on how to do this in German here or in English here.

Why am I suddenly getting an error message when I log in to the app?

On registration, we send you an email. This contains a link to confirm your email address. In the first 48 hours after registration, you can also simply use the MIYO app without confirming. After expiry of these 48 hours, the account is blocked unless the email address has been confirmed. If we need to resend you the email with the confirmation link, please send an email to service@viratec.at.

Why is my sensor showing such low moisture levels?

When positioning the sensor, it is very important that the earth is in contact with the measuring surface and there is no trapped air. If your sensor displays 0% over a prolonged period or never rises above e.g. 30%, please check whether the earth is well pressed onto the measuring surface. If necessary, reposition the sensor.

Why does my sensor display an exceptionally/unrealistically high temperature in direct sunlight?

The ambient temperature displayed appears too high at first glance, but this is easily explained: Normally, thermometers measure ambient temperature in the shade at least 1.5 metres above the ground, and they are protected from wind & rain. However, our sensor is located on the ground and it is exposed to direct sunlight and weather. The ground also stores and reflects a lot of heat, and the sun additionally warms the case. The measured values are therefore not wrong, and they provide important information to MIYO for optimal watering of your plants.

Why does watering stop after a few minutes and then start again shortly thereafter?

With our many years of experience as watering specialists, we have found that it is better to water in multiple intervals. This minimises the effect of different soil conditions by leaving sufficient time for the water to seep down. If the water has completely saturated the various layers of soil after a few minutes, the ground moisture is measured again. Based on the moisture that has actually arrived at the roots, there are further rounds of watering until the desired moisture level is achieved.

Why does MIYO not water even though the soil around my plants is very dry?

One reason might be that the local weather forecast has indicated rain soon.
Watering is also not triggered if the outside temperature is below 4° C or the sun is shining too intensely. This prevents damaging freezing or burning of the plant.
It may also be that automatic watering has been deactivated because the battery has not been charged adequately in the last 14 days.
Also ensure that you have not selected “pause watering” by mistake in the watering settings for each area or an incorrect lower moisture limit is set.

After initial successful installation, automatic watering is deactivated for safety reasons until the valve battery has been charged for 60 minutes. In this period, however, you can start watering manually with “Water now”.

Why do I have to set watering times when MIYO waters based on requirements?

Yes, MIYO is more than an ordinary programmable water timer. But you still need to define watering periods in which watering is permitted, even though MIYO then individually determines when watering is necessary. This means you can define when watering definitely should not take place. One frequently used scenario is that on Sundays watering the lawn is only permitted in the morning as you are often in the garden in the afternoon and naturally don’t want to get wet. You can program every day of the week however you please.

Why do I need the ``Water now`` function in the app?

There are various possible scenarios for this.

The most common reason is both simple and ingenious: It’s a gorgeous summer day and you’re having friends over for a barbecue, or the neighbour is peeking over the fence with evident curiosity. In both cases, you naturally want to show off your MIYO intelligent garden watering system. Since you don’t want to wait until the next regular watering time, you can trigger watering by simply pressing a button in the app. It will then start within 15 seconds. We affectionately refer to this scenario as the show-off function. Your audience will be delighted!

Another scenario is that you are in the garden checking MIYO’s work and you notice that you set watering thresholds too low and the soil around your precious plants is too dry. You can correct the situation immediately by watering with the “Water now” function.

Where can I see how often and how much MIYO has watered?

In the app, you’ll find the ‘Statistics’ function for each watering area.

I want to water different watering areas with different programs. How do I do that?

Install a splitter directly at the water tap. Now you can attach multiple valves downstream from the splitter.

Then you place one sensor in each of the desired watering areas. Make sure that the linked valves and sensors are assigned correctly. You can find out how to avoid mixing up the devices here in the FAQs as well.

Are the sensors and valves frost-proof, and can I leave them in the garden over the winter?

No, all mobile devices (sensors and valves) must be removed for the winter – i.e. an outdoor temperature of 4°C or lower – and stored in the house. As soon as the sensor measures a temperature of 4°C, you’ll receive a warning in the app that it is soon time to remove the devices for winter. At a temperature of 0°C, you will receive an error message that the sensors and valves have to be removed immediately.

How can I shut down MIYO for winter and then re-activate it in spring?

You can find information on this process in the operating instructions.

Does the battery remain charged over the winter or do I have to charge it in the interim?

When you shut down MIYO for winter, you can activate winter mode in the settings for each watering area. This puts the devices in an energy-saving mode that can run for several months on battery power without needing a recharge.

How often does the cube receive sensor values?

The cube and sensor have a direct wireless connection and communicate several times a minute.

Why do the sensors and valves communicate with the cube using radio rather than wifi or Bluetooth?

We deliberately decided against equipping the sensors and valves with wifi receivers. This allows a greater range and spares you the inconvenience of having to buy and install a wifi repeater for the garden.

We also concluded that a Bluetooth connection would be less than ideal because the range is often insufficient and the connection is not reliable.

Where can I find technical details for MIYO?

Under Downloads/Technical Information – here you’ll find information for all devices.

What is the function of the cube?

The cube is set up in the home and combines the plant data from the sensor with the current weather forecast and your personal settings. It can also be set to take into account signals from your smart home device. It is the brain of the system and decides whether, when and how watering should occur in one or more watering areas. Only one cube is needed for each watering system. It can be used to manage more than 200 valves and sensors. The cube is the only device that can connect to the Internet and the cloud through an ethernet connection.

How does the cube get my location information so it can take the local weather forecast into account?

You enter this information when you set up your garden in the app.

What and how does the sensor measure?

The sensor measures the soil moisture at a depth of 10 cm. It also measures the light intensity and the air temperature. A sensor surface at the end of the sensor neck measures the moisture.

What does lx mean?

Lx is the SI unit for illumination.

How much light do the batteries in the sensors and valves need?

The solar cell must not be covered. It takes roughly 25 hours of sunlight to fully charge the battery. On average, roughly one hour of direct sunlight per day is enough.

How can I tell if the battery charge in my sensors and valves is too low?

You’ll receive a warning message from you app if the solar cell has gone 7 days without sunlight or if the battery hasn’t been sufficiently charged in the past 7 days. If the battery completely discharges, you’ll receive an error message.

Are all the costs up-front or are there operating costs as well?

The costs for the hardware are one-off costs. The app is free to download. Within your home wifi network, controlled from home, there are no costs. If you have connected MIYO with the Internet, however, you may incur costs from your mobile/Internet provider.

What does the bar display mean in the app settings for sensors & valves?

The bars indicate the radio strength of a sensor/valve to the cube. The greater the distance, the fewer bars are displayed. There is no battery charge status indicator.

Can I also connect the valve to brass fittings?

As the connections on the valve are plastic, we also recommend using plastic fittings. Brass fittings do essentially work, but it may be that the connection is looser and thus more sensitive than with plastic fittings. Suitable fittings from our partners can be found in our webshop.

Where can I find customer service information?

 All of this information is available under Service.

Why is my sensor or valve not contactable?

One reason may be that the device battery is empty. In this case, you must already have received warnings and error messages (alarms) as push notifications. Place the device in the sun for 30 minutes to charge the battery. Charging does not work through a window pane.
Another reason may be a lack of radio connection.
Ensure that no objects are shielding the cube.
Note that sensors and valves have the best possible radio connection when the WLAN-plant icon on the sensor/valve points in a direct line of sight to the cube. Should the connection fail frequently, turn the sensor/valve 90° to the left or right.
If that also does not help, reduce the distance between the devices by placing the cube in a different position in the house. When choosing the location, ensure that the cube has to overcome as few walls and other obstacles as possible in the line to the garden. Regarding this, please also see the FAQs for “Where is the best place to install the cube?

How does a loss of router/Internet service to the cube affect the MIYO system?

MIYO continues to work independently and take care of your garden.

It just means you can’t access the app.

How does loss of power to the cube affect the MIYO system?

Unfortunately, MIYO cannot work without electricity. As soon as the power supply is restored, everything will resume working on its own and your watering settings are unaffected.

If the valves lose contact with the cube, the emergency program takes control of the valves and watering is automatically halted.

How is MIYO updated and what do I have to look out for?

Updates are done automatically.

The only requirement is that the cube is connected to the Internet. Even if you prefer a system that is independent of the cloud/Internet, with no wifi connection in normal operation, we recommend connecting the cube to the Internet at least one day a year to enable scheduled software updates.

Once the cube has been updated, it passes the update on to the sensors and valves.

During these updates, your MIYO functions as usual.

What (personal) data is stored?

You can find information on this in the data protection declaration available in the app stores and here on the website.

Does MIYO send the data to the cloud?

If you’d rather avoid another cloud service that collects your data, MIYO can also be restricted to just your home wifi network. The cube will still draw weather data and updates from the cloud, but no personal data will be transferred from the cube to the cloud.

Nevertheless, you can activate the cloud at any time in order to use the MIYO app outside your home wifi network and use online services like IFTTT.

Does the system include theft protection?

As every device has a unique serial number, we can track where the stolen device is installed and take appropriate action. So be sure to report any theft to our service hotline without delay.

You will also receive a warning in the app whenever the cube loses contact with the sensors or valves.

Does the tap have to be open at all times, and is this safe?

Yes, the tap to which the valve is attached must be open at all times. Control of the opening and closing is handled by a reliable magnetic valve. Similar protection is stored in the logic of the cube and the valve to prevent water damage. You are immediately informed of malfunctions and problems via the app.

To prevent leaks, we recommend only using the system’s own valves and accessories.
