The Status LED is illuminated steady red when an alarm condition is detected (further details are
provided later in the document).
The Status LED blinks green when the processor is booting. The LED is controlled to blink green by the
software, as early as possible during the boot sequence. The green blink rate during booting increases
as the booting process proceeds towards completion until the Status LED is lit steady green, when the
netAQUA transitions from the boot sequence to operation.
3.5.2. WiFi LED
A dual-color WiFi LED is provided to the outside of the netAQUA enclosure, at the bottom, to the left of
the four control pushbuttons.
The WiFi LED is Off when the WiFi interface is not enabled in the Browser Interface.
The WiFi LED blinks red when the WiFi interface is enabled, but there is no WiFi connection.
The WiFi LED is steady green when the WiFi interface is connected.
The WiFi LED is steady red when there is a WiFi failure.
On the non-WiFi versions of the netAQUA, the WiFi LED is not operational.
3.6. Monitoring
The netAQUA includes functions to check local temperature, local rainfall, Internet temperature and
humidity, and water flow.
3.6.1. Local Temperature
A hardware interface is provided on the netAQUA to attach a temperature sensor. The user can enable
extended watering times via the Browser Interface, when a temperature threshold is crossed.
Detection of temperature sensor failure or unintended removal is provided. When the temperature sensor
is detected failed or removed, any extra watering settings are disabled and watering follows the timer
control settings.
3.6.2. Local Rainfall
A hardware interface is provided on the netAQUA to attach a standard, off-the-shelf rainfall sensor. The
user can disable watering via the Browser Interface, when a rainfall threshold is crossed. The rainfall
sensor supported by the netAQUA is of the Normally Open type, meaning that detected rainfall creates a
contact closure that is then checked by the netAQUA.
3.6.3. Internet Temperature and Humidity
A software interface is provided on the netAQUA to enable localized temperature and humidity verification
from the Weather Underground Internet weather service. The user can extend watering times via the
Browser Interface, when a temperature threshold is crossed, or shorten watering when a humidity
threshold is crossed.
Location can be input via a city/state combination, zip code, latitude/longitude data, or weather station ID.
3.6.4. Water Flow
A hardware interface is provided on the netAQUA to attach an accurate, high quality water flow sensor.
The flow sensor averages the flow rate over a number of cycles, once a cycle has been programmed. If
enabled an alarm will be issued, if the flow rate exceeds the average by an amount specified by the user.
Conversely, an alarm will also be issued if the flow rate settles below the average by an amount specified
