Description: This product needs to be used with the Tuya Zigbee gateway. The Smart Air Manager is a smart device that remotely monitors the air environment. It can also detect 6 environmental parameters such as PM2.5, formaldehyde, VOC and other toxic gases, CO2, temperature, humidity, etc. When environmental parameters exceed the standard, Tuya smart home air conditioners, fresh air fans, humidifiers, and air purifiers are automatically used to optimize the home environment. Note: Do not place the air steward in areas with excessive oil smoke, strong convection air or high concentrations of organic gases for a long time, otherwise the sensor will be damaged. The air steward uses the automation function of the Tuya APP to link other equipment in the room, such as air conditioners, fresh air fans, air purifiers, humidifiers, etc., and automatically control them when they reach a predetermined threshold. 1. Click the "Smart" button at the bottom of the APP homepage to enter the smart scene interface. Click the automation button at the top, and then click " " to enter the smart setting interface. 2 Click "Create Smart Automation Configuration" to enter the setting conditions, and select from the "Device Status Change" option. Intelligent air steward, the trigger condition selects one of the six air environment parameters PM2.5, formaldehyde, VOC, carbon dioxide, temperature, and humidity. 3. Select the parameter threshold. There are three condition models of less than, equal to, and greater than one. Set one of them and select Next step 4. Create a setting task, select operating devices, and select devices in the control device list, such as lamps, curtains, air conditioners, fresh air fans, humidifiers, air purifiers, etc. Select specific commands in the device's function interface for control, such as on, off, time or others. Then select Next Step 5. Edit the automation name, select the automation effective time and click Save-Enable Now. The automation setting is successful. When the air steward detects that the environmental parameters reach the default value, it will automatically control the device. An air steward can set multiple intelligent automation control devices at the same time.
