Some action not taken into account when multiple writes are triggered at almost the same time in HA #109

Hi Arnold, I've got an issue that if multiple commands are sent to the bridge at almost the same time (they're all triggered via a HA automation), one of the command isn't effective. In the example below, I've got 2nd, 3rd and 5th which all update the controller state. Without the 5 second delay (4th action), the 5th seems to be ignored.

I think in one of the recent changes, some command buffering was added. Wondering if this is due to some race condition?

Hi Bao, my mistake, the release notes for v0.9.53 indeed included a message that buffering was added, but that change was moved to a later release. It is currently under test. I will send you the test version by e-mail.

@Arnold-n could you send me the test version as well? I have the same problem... as a workaround I configured some Wait-Timers in the automation. But this is not reliable.

Bao received the F-series test version. I am working on the E-series version and will send it to you later.
