I have gone through the very same issue : bulb found on phone (both yeelight and mi home apps), trying to add it in the device list and connection timeout finally… It’s been 3 weeks and 150 times (my estimation, not kidding !) I have tried to add the bulb in my network and device list and I finally succeeded today !
Here is what I did : turn on & off the bulb every second and sometimes even faster during maybe 1 minute. When I say “faster” I mean the bulb didn’t even had the time to show up before I shut it down again… Just on/off like a crazy ! The bulb did reset several times but I kept shutting it down again and again quite fast. Ok, that looks desperate behavior, but hey… I launched Mi Home app again (connected to Main China server) and bulb connection worked immediately !!
I’m now happy . All is working smoothly !
Maybe you can try this if you are as desperate I was and confirm you get as lucky I am… I hope it can work for some of you and help you getting back to relaxing mood under the nice yeelight bulb light
It seems the bulb is in factory mode, please have a try with:
I have remove one lamp from my device then I reset it and try to find from Yeelight APP 18.104.22.168 which I have in my phone.
From Yeelight APP I cannot find any of my lamps. I reset all lamps several times. I uninstall and install Yeelight APP also several times. I try from Mi Home APP also without any luck. I try with 3 different routers also I cannot find any of my lamps. I can see them on Wi Fi I can connect to each lamp wifi but cannot see them inside the APP. All lamps have the latest Firmware. All lamps have excelent wifi signal because before I delete them all lamps were working fine. I try with all servers but still I cannot find any lamp to connect.
You need to connect the lamp again after you reset it, so please try to connect them again.
