Thanks for your help. Will open an issue in zwave-js and ask them to look at it. Will add this issue as a link.
Thanks for great help.

Seems Zwave2Mqtt is generating the configuration and state. I am not sure this is supported. Can you share the MQTT config payload for the cover that is missing the controls, and may be a state payload matching the state_topic in the config?

[radhoo2k10]

@jbouwh I need some guidance on how to to find the config payload. This is the first time I'm using the mqtt explorer.
Is it there I can find the payload?

[jbouwh]

Some where under homeassistant/cover/xxxx/config

[radhoo2k10]

homeassistant/cover/Kjokkenvinduet_screen/position

[jbouwh]

What is the payload on topic zwave2mqtt/Kjokkenvinduet_screen/38/0/currentValue ?

[radhoo2k10]

{

}

[jbouwh]

Can you share the content of topic zwave2mqtt/Kjokkenvinduet_screen/status ?

[radhoo2k10]

I don't see that topic.

[jbouwh]

Okay, it may be that topic is not retained, so it is only shown when it is published. That should happen when the item comes available.

[jbouwh]

I see this in the logs:

2024-05-30 18:33:09.397 ERROR (MainThread) [homeassistant.components.mqtt.mixins] Error 'string value is None for dictionary value @ data['command_topic']' when processing MQTT discovery message topic: 'homeassistant/cover/Kjokkenvinduet_screen/position/config', message: '{'command_topic': None, 'position_topic': 'zwave2mqtt/Kjokkenvinduet_screen/38/0/currentValue', 'set_position_topic': None, 'position_template': '{{ value_json.value | round(0) }}', 'position_open': 99, 'position_closed': 0, 'payload_open': 99, 'payload_close': 0, 'availability': [{'payload_available': 'true', 'payload_not_available': 'false', 'topic': 'zwave2mqtt/Kjokkenvinduet_screen/status', 'value_template': "{{'true' if value_json.value else 'false'}}"}, {'topic': 'zwave2mqtt/_CLIENTS/ZWAVE_GATEWAY-zwave-js-ui/status', 'value_template': "{{'online' if value_json.value else 'offline'}}"}, {'payload_available': 'true', 'payload_not_available': 'false', 'topic': 'zwave2mqtt/driver/status'}], 'availability_mode': 'all', 'device': {'identifiers': ['zwavejs2mqtt_0xc7f1fc00_node115'], 'manufacturer': 'Fibargroup', 'model': 'Roller Shutter 4 (FGR-224)', 'sw_version': '8.0.0', 'name': 'Kjokkenvinduet screen'}, 'unique_id': 'zwavejs2mqtt_0xc7f1fc00_115-38-0-currentValue', 'name': 'Kjokkenvinduet screen_position'}'

The command_topic cannot be None.

[radhoo2k10]

Where does the error lay? Is it the zwave-js or zwave-js ui that needs to do something?

[jbouwh]

Is it the zwave-js or zwave-js ui that needs to do something?

Yes, the config invalid. As the command_topic should be string. It is optional, but then it should be omitted. This also means that it is not an issue with Home Assistant or the MQTT integration.

[jbouwh]

I'll close the issue here, but is okay to link to it.
