[BUG][HA] BL602 Magic Home not sending all channels for Home assistant Discovery

[arhi3a]

Describe the bug
I wanted to add MagicHome RGBW 12V controller (https://www.elektroda.com/rtvforum/topic4024917.html) to HA using discovery via MQTT. Unfortunately it sends only sensor information to HA sensor channel. It does not send information regarding led control or status therefore I can not control device from Home Assistant. It also does not generate preview of configuration payload.
To confirm the problem is conncted with BL602 Device i tried configuration on my 2nd module it had same issues but wifi led bulbs (other device) using BK7231N are configured correctly & sending full payload.

From webapp log view:

Info:MQTT:Queued topic=homeassistant/sensor/open_bk_led_5_temp/config, 1 items in queue
Info:MQTT:Queued topic=homeassistant/sensor/open_bk_led_5_rssi/config, 2 items in queue

This basically looks like RGBW device support request for HA. Or can you try "emulate cool" flag?
