4.2 Power-on initialization
When the product is powered on, the Blue indicator flashes slowly for 2 times and then stays on, and the
initialization is successful.
4.3 Pairing
After the product is initialized, short press the pairing button once, the device enters the pairing mode, the
distribution Green LED indicator flashes quickly, and exits the distribution network status directly after the timeout,
the timeout period is 60S.
4.4 Restore factory settings
Press the key for more than 30S, the distribution Green LED flashes 3 times, the device restores the factory

settings and enters the pairing state.
4.5 Button function
Pairing button:
Short press: when the network is not configured, it enters the network configuration state; when the network is
configured, it does not respond.
Press key time 8~15S, clear network information;
Press the key for more than 30S, restore factory settings;
Reset button: restart device.
4.6 Power-on default state setting
After the device is powered off, power on again to set the status of the relay after power on. The enumerated
values are as follows:
None: Power-off memory, after power-on, the relay keeps the state before power-off.
On: Normally open state; the relay is turned on after power-on again.
Off: Normally closed state, the relay will be disconnected after power-on again.
4.7 Configurable reporting time
The device status reporting time can be set by users according to their own needs, ranging from 1-64800
seconds, and the default is 60 seconds.
4.8 OTA function
The device supports the OTA function, and the device can be upgraded remotely through the gateway. The
OTA function requires a digital signature function, and programs other than the device cannot be upgraded.
4.9 Voltage detection
The product has a built-in lithium battery. When the external power supply is cut off, it is powered by the
built-in battery. When the voltage is detected to be lower than 3.8V-0.1V, the red LED will flash slowly 3 times,
prompting the user to charge. When the voltage is lower than 3.5V-0.1V, the red LEDs will flash fast 6 times, and
all functions will be turned off.
