This form is for reporting bugs. If you have encountered a bug, you should
generally have some log messages or device diagnostics to show something is
going wrong. If your problem is more of a question or a request for help,
then Discussions is
probably a more suitable venue.

Describe the bug
A clear and concise description of what the bug is.

When a light device is unavailable and brightness setting is changed (via automation), the following error will be thrown. This seems to break the receive loop as well so Tuya Local cannot try reconnecting to the device:
