I cannot determine responce witch current position -> are you sure that the ZNCLDJ11LM does support this?

[freenetwork]

I am not sure about that. Since I do not have a previous curtain model. I will capture messages the other day with a position for ZNCLDJ12LM

So it seems it isn't supported (Koenkk/zigbee-herdsman-converters#545 (comment)). That means that we can integrate it, can you make a PR?

[freenetwork]

I catch packets. Control message work from old model. Packets in my repo

Looks like a zigbee2mqtt assistant issue, discoveries for this device are in place (https://github.com/Koenkk/zigbee2mqtt/blob/dev/lib/extension/homeassistant.js#L608). Please open an issue there.
