Yeelight Connection Help

My LIFX does not appear in the results list when I want to connect it

  1. Make sure that your computer and your LIFX devices are connected directly to the same router and that there is no switch or similar network device in between.
  2. If you have a 5 GHz Wi-Fi network, please turn this off. Sometimes 2.4 GHz devices do not get along with it.
  3. Connect your computer to the network via Wi-Fi. Sometimes routers block the detection of Ethernet to Wi-Fi and vice versa.
    1. You can also temporarily install Lumia Stream on a laptop and connect it to the router. However, please do not use 2 Lumia Stream instances at the same time.
  4. If you find your devices with this method, you can switch back to an Ethernet connection.
  5. Make sure that no one else in the household is currently operating the devices via the LIFX app. You can’t use the LIFX app and Lumia Stream app at the same time.
  6. Restart Lumia Stream
  7. Restart your PC

I followed all steps but still can’t get my devices to work

  1. Perform a hard reset:
  2. For bulbs:
    1. Start with the LIFX
    2. Turn your light off and on at the wall 5 times slowly at consistent intervals
    3. Your light will flash to signify the success of the hardware reset
  3. For Strips:
    1. Find the reset button on the controller. It is on the side of the controller box.
    2. Hold it down for 10-15 seconds, and then release.
    3. The strip or Beam should then flash red, green, blue, and white
    4. (Note, you may still reset your Z or Beam Kit by cutting their power source 5 times as with our standard lights)
  4. All LIFX-colored products will flash red, green, blue, and white

I can connect my devices, but they keep disappearing from the connection again

  1. After connecting your devices to Lumia Stream, please give them a static IP in your router. Some routers are set to reboot every 24 hours and give connected devices a new IP. Lumia Stream will not be informed about this and therefore will be unable to recognize the devices.

Power cycle all parts of the system

Sometimes setup issues can be resolved by restarting the relevant devices

  1. Router: Follow the instructions for your router and restart it. In general, most routers can be rebooted by disconnecting the power for 30 seconds and then reconnecting it.
  2. LIFX lights: Disconnect the power supply from the mains for 10 seconds and connect it again

WiFi connection issues

It can be helpful to isolate your phone or tablet to WiFi, and disable mobile data. As devices don’t have internet available until connected with your home WiFi, it can at times, impact set-up.

  1. Turn off cellular data on your iOS or Android device
  2. Temporarily “forget” your surrounding WiFi networks
  3. Reconnect to the desired 2.4ghz network
  4. Once your device has connected you can turn your phone data back on

Network naming and password for 2.4Ghz and 5Ghz networks

Dual-band routers at times can route devices to the incorrect band, causing a failure in set-up. We recommend the following troubleshooting steps:

  1. Change the SSID (name) of the 5Ghz network band, so it does not match with the 2.4Ghz SSID
  2. Temporarily "forget" the 5Ghz network from your saved WiFi networks lists on your smart device WiFi settings.
  3. Please see the owner's manual for your router for how to complete this step

“Airtime Fairness” or “WiFi Multi-Media (WMM)”

Certain New routers in brands such as Asus, Netgear, Cisco, and Ubiquiti may have these features. It can cause low bandwidth devices such as smart devices to fall off the network or be non-responsive. To disable, complete the following:

  1. Log in to your wireless router settings
  2. Follow wireless > professional > airtime fairness > set to disable

AP Isolation

Also called Client Isolation or Guest Isolation mode, it provides internet to devices, without allowing them to communicate with other devices on the network. This prevents smart devices from being set up and further controlled via the local network. This is commonly used on College or communal networks.

  1. Disable AP Isolation on your router
  2. If trying to set up via a shared network you will need to switch to the private or hotspot network. Unfortunately, if you cannot disable this feature, you will be unable to set up your smart device.
  3. Please see the owner's manual for your router for how to complete this step

Firewalls, Port blocking, and VPN's

These can prevent a cloud connection for smart devices. Most smart devices can be controlled locally, however, it requires a connection for features such as schedules, IFTTT, Amazon Alexa, and more.  You will require access to certain ports to connect to their APIs

Also, check and make sure your phone and router do not have any AdBlock or VPN clients configured.

  1. For internet provider routers, contact your provider
  2. For a router you own, contact the manufacturer
