UPDATE: Something I tried worked, though I am not 100% what action it was, I am leaning toward rebooting the router resetting the connection to the hub to allow the hub to start sending sensor state updates again. This is weird, since it was using ethernet, not WiFi, and no other Ethernet or WiFi devices were having any problems.
However, if it was just the internet that was the problem, I thought I remembered Wyze saying that they would continue to store logs of all the sensor states offline internally in the hub, and that this would be available on the app GUI after internet is restored…though maybe this is just a future feature they intend to work on. So I went to check the sensor states, and none of the activity between 3:18am and 4:18pm (MST) is showing. All that data is MIA still, so I am guessing offline sensor logs are not yet implemented. This is good to know. Unless they are implemented, and instead this means that somehow my hub was frozen.
This situation has led me to a new insight. I sort of understand not having a power button on the hub…otherwise an intruder could easily shut if off. That kind of makes sense. It also hurts troubleshooting options though. If it locks up, I had no way to reboot the device to restore it except for maybe disconnect the power cord and wait all day for the battery to die. Or open it up and pull out the battery. Thankfully that wasn’t necessary this time. Perhaps Wyze could add a reboot button in the app like cameras have. Then a burglar can’t power it off or reboot it easily, but we could with our secure login to the app in some cases. Though I guess that would only help if sensors are spazzing, and the hub is still connected. It wouldn’t help if the hub itself is frozen and unresponsive. And the fact there is no rolling back firmware on the hub makes testing on the HMS/hub a lot riskier than other devices.
Thankfully we should still all be under warranty, but all this has brought up some good questions about what to do if the hub locks up. I guess delete it or re-set it up and possibly have to start over from scratch with adding dozens of sensors back to it? Anyway, I’ll keep an eye on it and see if anything else turns up.
