COLB update state in Home Assistant

[Dober]

hello!

I have COLB connected with home assistant by mqtt, when i restart home assistant all sensors turn to "unknown" to see the state again i have to restart COLB.
What have to do to maintain the state?

  - name: 'COLB-D1'

1: set ethernet work mode = TCP Server
2: use KC868-COLB PC software to enable "Auto Report" function.
3: then change to MQTT mode, connect to home assistant.

auto report is on
i think i have to set retain=on but i dont know how

[Dober]

can you tell me how to enable retain?

[admin]

KC868-COLB default retain is ON. what's your mqtt broker install on your HA? if installed mosquito, just check config setting.
