CB2S Not restoring saved state consistently about libretiny HOT 7 CLOSED

Note how it says "RTC" in the code you highlighted. Beken chips, unlike ESP, don't have any RTC memory for data preservation. Even if they did, a power loss would make it go away.

Thus, preferences are stored in the flash memory. Because of wear leveling, they are saved every 10 minutes or so, not upon each change. I believe ESP chips do the same and that they won't recover the very latest state after a power loss either.

Thanks for the info, I did, notice the Real Time Clock abstraction to flash. There are some use cases where we need to have an consistent restore state on the save without waiting for the s_pending timeout call back. I believe that was handled by the restore_from_flash schema option within esp based components. Perhaps I can look at it, just very new to the code base so it's not easy finding some elements within the heavy abstraction structure of esphome functions.

Ok, found the save interval define, its 60 seconds, that works for almost every case, unfortunatly its "global" not sure thats the best way to handle it. Also restore_from_flash appears to be required for esp8266 based devices.

Not a bug in any case, closing this, thanks.

Retested with the new parameters, we do have a bug. It failed to save an off state after 10min. Seems to be good on saving an on state consistently but not always an off state.

It's repeatable.

1. Starting from a off state after a power cycle.
2. Set state to on and wait 60+ seconds.
3. Power cycle and verify the on state occurs.
4. Set state to off and wait 60+ seconds.
5. Power cylcle. State save of off fails an will be on in the on state. (this will occur every time)
6. Now from the last point set the state to off, immediately followed by on and then finnish with an off state waiting 60+ seconds.
7. Power cycle, the state will be succesfully restored as the off state.

My assumption would be that only the on state triggers a flag to save the current state with a switch component.

Parameters were in error, it works as expected given enough time.
