Yeelight 1S bulbs not responding after ~1200h uptime

Hello all,

I have this recurrent issue for years… I wonder if I’m the only one or if someone has found a fix.

The issue:
My Yeelight LED bulbs 1S (YLDP13YL) all stop responding from HA after about ~1200h uptime.
A bit less actually, but I never managed to pinpoint the exact time. I would say between 1100h and 1200h, but every time I see it, it is close to 1200h.

I tried to restart HA, force wifi disconnection, disabling then enabling again LAN control on the bulbs, no luck.
The only “fix” is to power cycle the bulb.
It happens with all of them.
I’m running FW 2.1.7_0039.

Note: when it happens, it is still working more or less from Yeelight or Mi Home app, but it is slow and after a while, I lose control too from the app.

I’ll open a thread on yeelight forum too but if you have any clue or idea, I’ll be happy to read you :slight_smile:

Thanks

same here. Problem occurred with 2 ceiling lamps and 1 desk lamp. However one Yeelight bulb works ok.
I am afraid it is not a problem of HA/HA integration but something with Yeelight servers/firmware. I saw a lot of people asking for whitelist their ID. Not sure what for.

Did you manage to find a more precise uptime when it starts to happen?

It started 2 or 3 days ago. One day after updating HA to 2025.2, however I think it was a coincident as controlling lamps by Yeelight app is also problematic.

Hello,
I have the same problem with the same bulbs. With the official app they work fine for now. Actually I am a new user of the home assistant and unfortunately despite the incredible work that has been done with this app, for me the behavior is too unpredictable. :frowning:
These bulbs refused to work, the LaCrosse thermometer the weather station works very unstable… etc…

try to cut the power of bulbs for 20 seconds.

Have you checked the uptime in yeelight when it occurs?

How long is it?

Unfortunately, nothing is fixing my problem at the moment. Yeelight S1 bulbs have been completely invisible to Home Assistant for several days. In the Yeelight app they work without any problems. Apparently the integration just broke after one of the latest updates. About 1 month ago, I decided to test Home Assistant for the first time and then I was impressed that these Yeelight bulbs were automatically detected absolutely without any problems but for about 1 week they have been gone :slight_smile: From my brief experience, only my Zigbee devices and a few Blitzwolf (Tuya) sockets work most reliably and smoothly.

same problem here with my ceiling lamp. Stopped working in HA and it is very slow in official app. I think it has to do with the yeelight software.

Can you check the uptime in yeelight app?

1322 hours

Yes, it looks like the same issue.
What is your lamp reference?

Sorry, it doesn’t match this specific issue. It’s not related.

The issue in this thread is about losing control after ~1200hrs uptime. Restarting the bulb “fixes” the issue until it reaches 1200hrs again.
