Smart Color String Lights use RGB LEDs, allowing you to choose from millions of colors.

In order to successfully connect Atomi Smart devices, a 2.4GHz connection is required.

The 2.4GHz frequency waves travel further than the 5GHz. This means that if your device is in another room or far from your phone, you will have a better signal reception (compared to 5GHz) which is essential for your smart device to function correctly and stay online.

All modern routers come with 2.4GHz and 5GHz. Depending on your router type, these bands may appear as separate WiFi networks (Example: Name-2.4GHz and Name-5GHz) or combined. If you only have one WiFi network, you should still be able to connect since the Atomi Smart app automatically finds the 2.4GHz frequency when connecting to your router.

However, if you experience any issues, please follow the points below:

– Make sure that you are connecting to a 2.4GHz network

– Keep your mobile device close to the router during connection

– If you have two SSID for your WiFi (Example: Name-2.4GHz / Name-5GHz), please temporarily disable “Auto-Join” on your Name-5GHz network)

– If you have two SSID for your WiFi, make sure that your 2.4GHz and 5GHz WiFi have different names

– If your router gives the option to disable the 5GHz network, please disable it temporarily

– Disable any VPN apps/services in order to connect successfully

– If you are having issues to connect, turn on Airplane Mode (Keep only WiFi activated when connecting your smart device)

– Make sure that you’ve entered the correct password for your 2.4GHz WiFi on the “Select 2.4GHz Wi-Fi Network” screen (Case sensitive, and make sure that there are no extra spaces)

– If you have too many devices connected to your 2.4GHz (more than 10), please turn off some of them temporarily and retry connecting your smart device to the app

– If you have a Mesh router, you may not be able to manually switch to a 2.4GHz frequency. Since this frequency travels further than the 5GHz, you can force your device to connect to it by moving your phone far from the router

– If you are still experiencing issues to connect, delete the app and reinstall it

– If the issue persists, restart your router

Make sure your Atomi Smartdevice is plugged in and the lights are blinking. If not, unplug your Atomi Smart device and plug it back in to reboot. If you still have issues, press and hold the power button for 10 seconds. Note: For older devices, you may be required to press and hold the power button again for another 10 seconds. The atomi-smart-XXXX should appear on your network list after a few seconds.

Use your smartphone to confirm that you have at least two Wi-Fi bars in the vicinity of your Atomi Smart device. If not, move your Atomi Smart device closer to your router. (The list will refresh every 10 seconds).

Make sure you entered the correct WiFi password during the WiFi setup. Check if there are problems with your internet connection. If the WiFi signal is too weak, reset your WiFi router and try again.

Force quit and re-launch the Atomi Smartapp.

Press and hold the power button (on the power box) for 10 seconds.

No. Regardless of how long your smart string lights are illuminated they will remain safe to handle.

Wi-Fi networks come in a lot of shapes and sizes with many quirks of their own. It doesn’t mean your Atomi Smart device is malfunctioning.

If problems persist, please try these steps, in this order:

1. Force quit and re-launch the Atomi Smart app. Check to see if this fixes the issue.

2. Unplug your Atomi Smart device and plug it back in. Check to see if this fixes the issue.

3. Unplug your router and plug it back in. Check to see if this fixes the issue.

4. Delete and reinstall the Atomi Smart app. Check to see if this fixes the issue.
