MQTT dimmer values for min and max ignored

[UsefulVid]

The problem

I use a zigbee dimmer which has max and min values for its brightness.
They are setup correctly and according to my zigbee2mqtt log they are published to mqtt and home assitant.
They seem to be ignored when it comes to dimming. If I use the percentage bar the values are quickly exceeded and have no effect.

What version of Home Assistant Core has the issue?

core-2024.4.4

Yes and there I cannot set the max and min values. What do you need from my site?
The diagnostics?

[jbouwh]

At the MQTT INFO link you can find the configs for the device. The JSON is what is received by MQTT.

Can you please clarify what I should do? Yes I can find the information there. Do you want me to share it here?

Problem still persists with new updates

[jbouwh]

Based on the config published by Z2M:
If you control brightness it will be within the scale of 0 and 254.
When changed in HA the change command will be published at topic zigbee2mqtt/EsstischLicht/set. You can check it output with MQTT Explorer or and other MQTT client tool. That should work. If the light is not picking this op correctly, then this is mot likely an issue with Zigbee2Mqtt

I could only find this topic:
zigbee2mqtt/EsstischLicht
couldn't find "set"

[jbouwh]

It should appear if you change the lights brightness

What you see in the screenshot appeared after changing the max brigthness. Even after changing the brightness there is no "set".

[jbouwh]

Ah okay, will try to reproduce it later.
