Hi! I can't understand what happened. Suddenly my 8 bulbs died, no light at all but they are still visible in the app. When I turn the physical switch off the app updates and can't see them. When I turn the switch on they appear in the app again. I can even see the wattage usage in the app. I tried to change the mode, the brightness - nothing works. Help! :O
The Apr 22, 2026 update has ruined my experience. I’ve had them for two years with very few problems, now I can’t turn them on or off randomly at different points in the day.
Is anyone else experiencing this?
Hi everyone,
I’m having a really strange issue with my WiZ GU10 have 4 bulbs) smart bulbs and I’m trying to understand if this is a known problem or hardware failure.
After a connecting the bulbs to an HDMI sync box, the colors became completely incorrect:
When I select blue, the bulb turns green
When I select green, it turns blue
When I select yellow, it turns purple
When I select purple, it turns yellow
Interestingly, all other colors and brightness levels seem to work fine.
Here’s what I’ve already tried:
Resetting the bulbs multiple times (power cycling)
Removing and re-adding them in the WiZ app
Setting them up from scratch
Nothing fixed the issue.
What’s more concerning is that I had two other GU10 bulbs that were previously working perfectly, and they also developed the same issue on their own.
At this point, it feels like the color channels (RGB) are somehow mixed up or damaged, possibly triggered by the HDMI sync box or a power surge.
Has anyone experienced something similar?
Is this a known firmware/software issue, or does this indicate permanent hardware damage?
Any help or insight would be appreciated.
Hi!
For some strange reason, my Wiz app (or bulbs!) has suddenly started to malfunction. I thought I'd come on here to see if anyone knows how to fix this, before sending an email to Wiz's customer support.
When I select a color on the color chart, for example PURPLE (on the right side of the chart), the light bulbs show the color on the opposite side of the chart, in this case GREEN (on the left side of the chart??).
This has never happened before, I am very confused as to why this is happening. I am struggling to find both the cause and the solution to this problem.
The app is updated, I have removed the cache data, I have removed all the light bulbs, reset them, added them again and tried to find an answer on the internet without success. The light bulb model is GU10 (I think), and they are all updated (currently to version 1.37.0).
Has anyone else had this problem?
Does anyone have any ideas on how to solve it?
