Firmware Update for Yeelights Broke Connections to APP

🛎️ Get Help
1

I updated the Yeelights I have to the following version... 2.0.4_0022.... in the phone app and now the built in Yeelight App will not discover the lights. They have been reset and re-included into the phone app and all are controllable by the phone app.

Something has broke the connection between the built in app and the phone app. The built in app does not discover the bulbs anymore. I have made sure the switch for 3rd party is on for all bulbs.

What changes did they post in the version change log?

3

I'm very confused, I don't see any updates for Yeelight. What model?

4

The update was done through the phone app and I am not sure how to find out what the changes were. I will go searching.

EDIT: I have sent an email to Yeelight for more info on what the update did. I will report when I hear. I also placed a post on the Yeelight forum.

The bulbs are YLDP05YL. Tuneable white.

Anyone from the staff know about this problem. It appears that the new firmware has bricked the Yeelight bulbs. I have absolutely no control over them through the Yeelight App that is built in.

The bulbs are YLDP05YL and the latest firmware the phone app updated them to was 2.0.4_0022.

Any chance you have a fix for this? thanks

Did you turn off the LAN control switch and saved the setting? Then tried to turn on the setting again?

8

I have turned off the lan setting but not sure what you mean by saving it. I then turned them back on. It still doesn't find them in the HE Yeelight App.

Try disconnecting one bulb from power, then try again, or maybe rebooting the hub. Sorry I can't help, I just have color bulbs.

Well I rebooted everything and removed power to them. Deleted and re-installed the App. They all came in and I closed the App. When I opened the App again they were gone and it started searching again. This time none of them appeared.

11

I got it to work once and then lost power (switch got turned off) for a while. When I turned it back on I had to start the App again. Once again there are no bulbs being found.
Any help appreciated. I have no control over all 6 of them.

Here is what is in the log.
