Step-By-Step Guide

1. Download & install the app TUYA SMART onto your mobile phone. Follow the instructions in the app to setup your account / profile.
   • Google Play
   • Apple App Store
2. Remove the wifi interconnect smoke detector set from the box. There are 2 parts, the actual smoke detector and the wifi base.
   
3. The wifi base comes pre-installed with 2 AA CR14505 batteries. Remove the white battery protector strips by pulling them out. This powers up the wifi base.
4. Mount the smoke detector into the wifi base by turning clockwise and wait for a minute.
5. Press & hold the multi function button on the wifi base. Release the multi function button after 5 red flashes. You should see the button continuously flashing red now. If not, repeat Step 4.
   IMPORTANT: multi function button to be released only after 5 red flashes. If released earlier, it will reset the pairing of this wifi interconnect smoke detectors with other interconnect smoke detectors that we had paired for you prior to delivery to you. In this case, you will also need to re-pair this wifi interconnect smoke detector back into the cluster.
6. Return to app TUYA SMART and select Home.
7. Click to add a new device.
8. Select Add Manually.
9. Go to category Sensors.
10. Select Sensor (Wi-Fi) under Sensor category,
    
11. Your Wi-Fi SSID (Wi-Fi name) should auto show up. Enter your Wi-Fi password and click Next.
    
    IMPORTANT:
    • Please note that you must connect to the 2.4GHz Wi-Fi network or the pairing will fail.
    • Most modern routers will have both 5GHz and 2.4GHz Wi-Fi networks. It is highly recommended to have different Wi-Fi names for both networks so that you can accurately choose the 2.4GHz Wi-Fi network name. Please consult your router manual on how to give different Wi-Fi names.
    • If your router auto combines the 5GHz and 2,4GHz Wi-Fi networks together as a single Wi-Fi name, you may not be to pair successfully.
    • This is a limitation of today’s Wi-Fi technologies with TUYA SMART and not a limitation of our smoke detector.
12. You should see the multi function button light blinking red quickly.
    Select Blink Quickly.
    
13. Click Confirm the indicator is blinking rapidly.

16. Click Done to complete the process. You will be returned to app home screen. You should now see your paired wifi interconnect smoke detector in the home screen.
    

If Pairing Fails
