UART Sensor level control -> state can't be controlled by external MCU

[bullar]

I used the provided UART sensor example (1.9.0.15/2024-04-06) including the level control. All sensors are working fine except the state of the light can't be controlled from external MCU.

If the light is ON and the level control is set to any value (here 141): MQTT publish: topic 'zigbee2mqtt/0x00124b002a510550', payload '{"bind_command_l1":"on/off","brightness_l4":141,"link_to_output_l1":"no","linkquality":49,"state_l1":"OFF","state_l2":"OFF","state_l4":"ON","switch_actions_l1":"on","switch_type_l1":"switch"}'

the level can be controlled by external MCU with the command sequence: <STX> 0x13 0x6D <ETX> 0xDC to 109 for instance. or with sequence: <STX> 0x13 0x00 <ETX> 0x6F set to 0. Here the log: MQTT publish: topic 'zigbee2mqtt/0x00124b002a510550', payload '{"bind_command_l1":"on/off","brightness_l4":0,"link_to_output_l1":"no","linkquality":57,"state_l1":"OFF","state_l2":"OFF","state_l4":"ON","switch_actions_l1":"on","switch_type_l1":"switch"}'

But the state of endpoint 4 stays "ON" (here: "state_l4":"ON"). I didn't find a way to set it OFF from external MCU even with boolean data format (<STX> 0x03 0x00 <ETX> 0x5F') The same issue when trying to set the state from OFF to ON.

Btw, if controlling the state from ZIGBEE2MQTT GUI the following commands are send to external MCU: Set ON: <STX> 0x13 0x6D <ETX> 0xDC Set OFF: <STX> 0x13 0x00 <ETX> 0x6F

Does anyone have an idea what's wrong or is it a bug?

@bullar Could you please check the latest version where I've tried to resolve this issue?

Great, will test it when I am back home next weekend...
