If your LIFX light is powered on but not appearing in the LIFX app, the issue is usually related to local network discovery. Try the steps below to help your phone and light find each other again.
1. Restart discovery for both your phone and the light
These steps resolve most temporary visibility issues.
Turn the light off and on once
Close and reopen the LIFX app
Make sure your phone stays on Wi-Fi only (turn off mobile data temporarily)
Wait 10–20 seconds for the light to announce itself on the network
If the light still doesn’t appear, continue below.
2. Make sure your phone and light are on the same network
The light and your phone must be on the same 2.4 GHz network to appear locally.
Check that:
Your router hasn’t switched the 2.4 GHz network name
The phone is not on Guest Wi-Fi
- If you use a mesh system, make sure your phone stays connected to the same 2.4 GHz network the light is joining. Mesh Wi-Fi can move your phone to a 5 GHz node during setup.
3. Restart your router or mesh system
A simple restart clears:
stalled multicast
noisy client steering
bad DHCP leases
blocked discovery packets
mesh hand-off loops
Wait 1–2 minutes after the reboot, then reopen the LIFX app.
4. Disable router features that interfere with discovery (temporarily)
These features can block device visibility:
Airtime Fairness
WMM / Wi-Fi Multimedia
QoS / traffic shaping
802.11ax-only (Wi-Fi 6) mode
Band steering / “Smart Connect”
AP/Client isolation
IGMP snooping (if misconfigured)
They can be turned back on after visibility is restored.
5. Confirm the light didn’t join the wrong network
If your home Wi-Fi recently changed:
new SSID
new password
new router
merged/split SSIDs
ISP-replaced modem/router
Then the light may still be trying to use the old credentials and won’t show up.
If this happens, perform a hardware reset and add the light again.
6. Check if the light needs a firmware update
Old firmware can cause unpredictable visibility behaviour.
Once the light appears, update it under Settings → Firmware.
If the update fails, see Firmware Update Failed.
Still not showing up?
