I have several T310 to monitor temperature and humidity. They have been working with no problem for at lest 6 months, and then suddenly 2 of them stopped delivering data at the same time, midnight. They are online, visible in the app, but no data added after this moment. I tried the following actions: Change batteries - no improvement. Remove the sensor from the hub, and then connect again. Solved it at first. One sensor still works now, but the other one worked ok until midnight, then there is just no more data registered. It is still online.

One more strange feature. If I remove the battery and just leave it like that, the T310 is still visible as online. Perhaps the trouble is with the hub? Tapo H200, hw version 1.0, Firmware 1.3.2 Build20240424 rel 75425.

Maybe still a battery problem? But then why do they always stop working at midnight?
