3. Function Keys
Press the key to switch working modes.
In mode 1, mode 3, or mode 4, press the button for 3S
to clear the current display data.
In mode 2, press the button for 3S to switch units of
measurement to liters or gallons.
In mode 5, press the button for 5S to enter the pairing
state.
The LCD screen will enter the sleep mode if there is no
action or water flow for 1 minute in any mode.
Pressing the button will automatically wake it up into
the previous mode.

The product has five measurement modes: single-use
water consumption, real-time water flow rate, daily water
consumption, total water consumption, and current time
display.
3.1 Mode 1: calculates single-use water consumption
The LCD screen displays "SINGLE" water consumption in
liters or gallons. Suppose the flow meter stops running for
more than 30 seconds and restarts. In that case, it clears
the original accumulated data, begins re-accumulating, and
updates the display of real-time water consumption every
second.
3.2: Mode 2: measures the real-time flow rate
The screen displays the current flow rate value
every second in units of L/Min or GAL/Min. The
display does not show the leading zero; the
maximum value indicated is 41.9L/Min or
11.0GAL/Min. If the flow rate exceeds this value, it
will be displayed as HH.H L/Min or HH.H GAL/Min.
3.3 Mode 3: Daily Water Consumption
The screen shows the total water consumption
each day starting at 0:00. The LCD displays the
"DAY," and the unit is either L or GAL with a
maximum display value of 999999L or 999999GAL.
3.4. Mode 4: Total Water Consumption
The LCD screen displays the total water consumption when
the unit is powered on or starts operating. LCD displays the
"TOTAL in either liter (L) or gallons (GAL)," and the total
water consumption is updated every second.
3.5 Mode 5: Current Time
When the LCD is in the off state, press the button to show
the current time and connection graph if the product is
connected to the smartphone. If disconnected, it will show
the disconnection graph. For a paired but disconnected
device, it will display "-----." When the product is unpaired,
it will show "Uncon." Pressing the button again will switch
to mode 1.

5.1. Download the Smart Life App
Scan the QR code below or search for “Tuya Smart.”
Follow the instructions to set up a new account or log
in with an existing account.
Please proceed to the next step if you have already
installed the Smart Life APP.
5.2 Once paired, you can monitor the current
real-time flow rate and access daily, weekly,
monthly, and yearly water consumption.
5.3 On the app, you can view the water usage records for
single-use, total water consumption in 24 hours, total water
consumed within 1 year, and monthly water consumption
for up to 3 years. It can save up to 100 records if the device
is disconnected and automatically clears the earliest
records when the data exceeds 100
