I have this thing happen relatively frequently because my kids flip the lights on and off repeatedly.
Most of the time, I can ignore the green flashing light and it will eventually go back to the last settings that had and reconnect and function as normal.
When that doesn’t work, I just go through the setup process as if it is a brand new device. I don’t delete it from the app first because, as you mentioned in your post, if you do delete all of the app then it will either automations that were associated with it, or break them in a different way, or in some rare cases it creates what we call a ghost rule… A ghost rule is where an automation is not visible in the app anymore, but it is technically still in effect, so when you set up the device again from scratch, the ghost rule continues to run the automation and now it’s impossible for you to stop it, change it, delete it. There are only a small number of employees who have been able to figure out how to find ghost rules and remove them. So if you do end up deleting the device, I strongly recommend you disable any rules associated with it, and manually delete them before deleting the device. Ghost rules are rare and don’t always happen, but you don’t want them to happen. Anyway, back to what I do, usually without deleting the device from the app first, I just go through setup again as if I’m setting up a brand new device, and I usually try to name it with the exact same name that it used to have too. Once I do that, it almost always goes back to working again the same as it always did.
Now, there is an exception to the above. Recently, I had One or two original V1 white bulbs have this issue, and I went through setup again, and set up worked… Sort of… It said everything connected to my internet, and then right after that the bulb stops working as soon as I complete setup. I think they broke the setup process in recent app updates so that it isn’t always working correctly with some of the older bulbs. It would go through setup and complete setup and connect to the network and show up on my router and then refused function as if it was totally offline.
I explained the above experience because maybe there is something similar happening to you with the color bulb you are trying to reactivate. If you are going through the setup process and it is not finalizing the activation, maybe there is some problem similar to what I was experiencing.
Something that might work, if you are going through setup and not able to successfully complete activation, is that if you have Android, you could try side loading am older version of the app on your phone (ie: download an older version of the APK file from something like APKmirror, and install that) And see if an older version works better for setting up your color bulbs. Maybe they just messed something up in the process for setting up the original color bulb and nobody has noticed because all of the color bulbs they sell now are a newer second version of the color bulb which runs a little differently. So it’s rare for somebody to set up the older first version color bulbs now and maybe somebody just didn’t notice the setup problems? I’m reaching here, and maybe totally wrong, but since I had a recent experience where a bulb was not successfully setting up (even though It’s Wi-Fi Radio was clearly working for me to go through setup and tell it to connect to my router), I am thinking that there is some kind of bug either in recent app updates or the way the server functions. But not many people have reported these kind of issues, so I’m still trying to find other examples so that Wyze will believe me that it’s not an isolated incident.
Anyway, the summary is that usually if your bulb goes into pairing mode, you can just go through the setup as normal and it reconnects and everything goes back to functioning normally and keeps all of your automations. If it’s not doing that for you, then there could be some other kind of outstanding issue. Maybe the power outage broke something in the bulb. Luckily, they have a pretty long warranty on them of 3 years. You can call support to get it replaced, but they will first walk through troubleshooting including deleting it from the app and going through setup again.
