5. Device states
The device can be identified in 5 different states. Through the LED at the bottom, it is
possible to identify its current state. While, from the platform, it can also be identified
the “Awake” and “Sleep” states. The rest of the states will be displayed as “No
communication”.
The states are detailed below:
➢ AWAKE: LED shines 2 times every 6 seconds.
o Receives and runs commands (ON/OFF), power modes (ECO, PSM, RT)
and programs in real time.
o It registers information on the water meter hourly and after each event.
In addition, the history of opening and closing orders executed either
manually from the platform or by saved program(s) is saved in the
platform’s “Log”.
o It sends the following numeric values hourly to the platform: water meter
[m
3
], battery level and signal [%]. An update of these values in real time
can also be obtained by a communication test that can be performed
from the platform.
➢ SLEEP: LED shines 3 times every 15 seconds.
o It receives power modes updates (ECO, PSM, RT) and deferred programs.
The orders are saved in the cloud until the device switches to the
“Awake” state. Then they are uploaded to the device. The transition from
“Sleep” to “Awake” state depends on the power mode the device is in
(see Power Modes).
o It runs programs that have been loaded when it was in the “Awake” state.
o It registers data from the counter in the internal memory of the device.
The last saved value will be uploaded to the platform when the device
switches to the “Awake” state. It does not register in the “Log” of the
platform the opening and closing orders that are executed by programs
stored in the device.
➢ CONNECTING: LED shines once each second. In section “No communication”.
In case of failed connection, the device restarts automatically (LED off for 15
seconds) and it flashes again once every second. In PSM mode it will try 5 times,
and if it still does not connect, it will switch to “Sleep” state.
o Its reception, execution and logging behavior is identical to the “Sleep”
state.
