1. Introduction
ISysmart SGZ716, a humidity/temperature sensor with LCD display, acts as an End Device in ZigBee
network. It does not perform permit-join function as a coordinator or a router for other devices to join the
network. The humidity/temperature data can be also sent to the ZigBee network center wirelessly.
What is ZigBee?
ZigBee is a short range wireless transmission technology based on IEEE802.15.4 standard and supports
multiple network topologies such as point-to-point, point-to-multipoint, and mesh networks. It is defined for
a general-purpose, cost-effective, low-power-consumption, low-data-rate, and easy-to-install wireless solution
for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building
automation and home automation, etc.

5. Setting up SGZ716
5-1. Turn On SGZ716
To manually turn on SGZ716, press the Binding Key once.
When SGZ716 is first time used or after resetting → it will try to join the network.
When SGZ716 is in a ZigBee network → it will send out the device data, like IEEE
address/Network address, and the LCD display will show for 2 minutes.
When SGZ716 was in a ZigBee network, but by any change it is offline → it will start to rejoin the
ZigBee network.
5-2. Join the ZigBee Network
After SGZ716 is turned on, it will search for an existing ZigBee network and send a request to join the
network automatically. While SGZ716 is under the coverage from a coordinator or a router whose
permit-join feature is enabled, SGZ716 will be permitted to join the network.
Step1. Enable the permit-join function (valid for 60 seconds) of a coordinator or a router (please
refer to the user manual of the coordinator or the router to enable the permit-join feature).
Step2. Turn on SGZ716. It will start to search and join the network.
Step3. The icon will flash once when it finds out a network to join.
Step4. The icon will stay on after it is joined successfully.
SGZ716 will try 3 times to join the network. After it is failed to join the network, it will go to sleeping
mode and automatically wake up to find out a network to join every 15 minutes.
5-3. Binding
SGZ716 can be bound with the HA Temperature/Relative Humidity device .
Step1. Press and hold the Binding Key for 3 seconds to broadcast the binding request. The LCD will
show once and display . The icon will be flashing. Step2.
Enable the binding feature of the HA Temperature/Relative Humidity device.
Step3. The LCD display shows after the binding is completed; otherwise, it will show

.
SGZ716 can be bound with up to 10 devices.
5-4. Sleeping Mode
SGZ716 is designed to go into sleeping mode for power-saving in some situations:
A. While the device is in the network → the sleeping period is 5 minutes; it will wake up
every 5 minutes to keep online.
B. When it doesn’t find a network to join → SGZ716 will go to sleeping mode. It will wake up
every 15 minutes to search a network to join.
C. Once SGZ716 was joined to a network and by any chance the network is no longer existed
or the device is out of the network → SGZ716 will wake up every 15 minutes to find the
network it joined before.
It never keeps in sleeping mode and continues to find out a network every 15 minutes. This condition
would consume up to 30 times power spending compared to normal-operating status. To prevent this
unwanted power consumption, we recommend that users remove the batteries to power off the device.
5-5. Identification
According to the received Identify Times, the LCD display will show and the icon will
flash N times (N = Identify Times. Period = 1 second. Duty cycle = 50%.)
5-6. LCD Display
Users could use the setting key to switch the readings of Temperature → Humidity → Battery Voltage.
To display Celsius/Fahrenheit for temperature, press and hold the setting key for 3 seconds to switch the units.
5-7. Battery
When the operating voltage is lower than 2.5V, the LCD display will flash once and will show the icon.

5-8. Restore to Factory Setting
To restore it to factory setting, please follow the steps:
Step1. Press and hold both Binding Key and Setting Key for 5
seconds. Step2. Release the button after the LCD display flashes.
Step3. After the display shows , the restore is completed.

7. Important Maintenance Instructions
Please keep the device in a dry place. Precipitation, humidity, and all types of liquids or moisture can
contain minerals that corrode electronic circuits. In cases of accidental liquid spills to a device, please
leave the device dry properly before storing or using.
Do not use or store the device in dusty or dirty areas.
Do not use or store the device in extremely hot temperatures. High temperatures may damage the
device or battery.
Do not use or store the device in extremely cold temperatures. When the device warms to its
normal temperature, moisture can form inside the device and damage the device or battery.
Do not drop, knock, or shake the device. Rough handling would
break it. Do not use strong chemicals or washing to clean the device.
Do not paint the device. Paint would cause improper operation.
Handle your device, battery, and accessories with care. The suggestions above help you keep your device
operational. For damaged device, please contact the authorized service center in your area.
