Problem with TS0601 Dimmer handling brightness from Home Assistant

[eatoff8]

What happened?

The light turns on and off fine. but when turning on with a brightness command, the light ignores the brightness and just toggles on at whatever the last brightness was set to.

An example is I have the light 100% during the day, and only 5% brightness between midnight and 5am. This works fine with my philips zigbee bulbs. What happens with this dimmer switch is that it will turn on at 100% brightness at 1am. or if i manually set it to 50% brightness and then run the automation to turn on at 5% (or 100%) it will turn on again at 50%.

A workaround that i am currently using is the template light found here in this issue - https://github.com/Koenkk/zigbee2mqtt/issues/19513

What did you expect to happen?

I expect the light to turn on with the correct brightness set

How to reproduce it (minimal and precise)

Set a brightness and then turn off the light. Then use a service call to turn the light on at a different brightness. that brightness will be ignored.
