Overview: The relays is paive output(Dry contact), No matter the power you supply in the input, the output don't have any voltage, you also need to supply power in output.so the connectted device in the output can work. Two Working Mode 1.Self-locking : each channel could be switched on/off seperately.You can turn on/turn off all channel at the same time.2.Inching mode : Switch on one channel,the channel will be automatically closed after 0.5 seconds .Other channel is same as the channel.If you need to change the mode,you need to change it in APP Features: Two Input PortsYou could choose Micro USB 5V port or the screw terminal port to supply power in the input to make the pcb board board work.Dry Contact/Paive OutputNo matter the power you supply in the input, the output don't have any voltageIf you do not supply power in output port, the connectted home appliance can't work, you also need to supply power in output.TimerThe connectted home appliances can be automatically turned on/off according to the time schedule.Each channel can set different time schedule. Function APP Remote ControlYou can control the connectted home appliance in Tuya or smart life APP anywhere and anytime.Such as light, electric kettle, electric rice cooker, electric curtain, etc.RF433 ControlThe WIFI Module support RF433 Frequency,and you can control the WIFI module by RF433mhz remote controller.Mobile Phone ControlWhen you go outside or at home,You could control the module in your smart phone by 2.4Ghz WIFI or 2G/3G/4G mobile network(Note:The router need to online and the WIFI module need to keep a close distance with the router)Voice Control Compatible with Alexa and Google Aistant, you can use the voice control to turn on/off the connectted home appliances .Share ControlOne device can control by Multiple phones,you can share the wifi module with your family.Group Controlone phone can control Multiple smart device.You can add the wifi module and other smart device in a group,and then you can turn on/off all smart device at the same time.Smart ScenarioCreating smart scene to trigger ON/OFF all WIFI Smart Device by departure mode, home mode, temperature, humidity, or other conditions.
