Bug: YeeLight devices always offline

Hello, i am using YeeLight smart bulbs. For 3 days my all lights gone offline and never come back. I realized in SmartThings web my lights types seen “placeholder”. I checked out the list and i didn’t found YeeLight or something closer to that type. In my opinion there is an error between SmartThings and YeeLight services. If anyone use same bulbs can u tell me what is your types? Thanks

All cloud to cloud integrations now have the “placeholder“ type. you connect to the integration through the app by connecting to your account for that device manufacturer.

It’s already connected with manufacturer service. Also i tried remove and reconnect it.

same for me, but strangely only 3 of the 4 appear offline all of the time now.
I have 2 lights showing as yeelink.light.colour1 and 2 lights showing as yeelink.light.colour2 according to device info in the Yeelight App.

Today, i struggled on SmartThings Web. I tried changed type of my YeeLight bulb with every bulb option in list. Finally i found an option bring my bulb back online. I changed type to “Simulated RGBW Bulb” and my bulbs came back online. Now my belief that this is due to the platform has become definite. There is an bug about this and it needs to be fixed immediatly.

I have the same problem with Yeelight for the last few days, existing automation works, bulbs show offline state. Deleted devices and recreated Yeelight connections and automations. Correct state for a day and now 4/5 bulbs are showing as offline. The bulbs appear and operate correctly in the Yeelight app.

yea its certain bug. Did u try my solution?

Yes I did. The bulbs showed as online, but they would not respond to on/off. I would get a “network error has occured” message. I have changed it back to “placeholder” for now.

Tried changing to Simulated RGBW Bulb again, this time it is working. Thanks for the suggestion.
