Maybe it takes more than one factory reset? I don’t know why, but in another recent topic a community member wrote about finally getting a problematic Bulb Color to appear online again after trying a factor reset for a fourth time:
If I was going to do that much work, I’d probably start with a single bulb, do a full factory reset on the bulb (which it seems like you’ve done), and do a complete purge of my app data to grab a fresh profile.
This is how I would get a clean copy of my account profile/settings on Android (click/tap to expand):
- Clear the in-app cache: From the Wyze app’s home screen, navigate to Account ➜ App Settings ➜ Cache File Size ➜ Clear.
- Navigate back one screen to Account and tap Log Out at the bottom.
- Swipe the Wyze app out of the running Android apps.
- Long-press on the Wyze app’s launcher icon (on the phone’s home screen or wherever you tap to initially open the app) and then tap App info in the pop-up menu.
- Tap Force stop on the App info screen (may need to tap OK to confirm) and then tap Storage & cache.
- Tap Clear cache and Clear storage on the Storage screen.
- Back up one screen (back to App info) and then tap Open and proceed to log back into your Wyze account/app. (Optionally reboot the phone at this step for good measure and then launch the Wyze app after the fresh boot instead of relaunching it immediately from this screen.)
Note: I don’t know what the options would be for modifying these steps on iOS since I don’t use that platform.
If it’s easily done, I’d probably also reboot the home network (I don’t have a good reason but generally like to do a controlled reboot after a power outage, just like I prefer to initiate a clean reboot if I have a PC crash) and temporarily relocate the bulb close to your gateway or a wireless access point in order to give it a strong signal to connect to. That’s where I think I’d proceed after the other troubleshooting you’ve described.
