Konnected a) board blinking decode; b) no sensor updates in HA

I am not sure if that related somehow… But I have migrated to SSD USB my HA instance running on RPi4. Today I found my Konnected boards blinking by build-in blue LED some code constantly : 2 long and in a second about 12 short flashes. I am able to check status via their web-servers all ok and get status XML . But what is this blinking code mean 2+12 ?? Very close to the issue reported here Blue Light Blink Deciphering

Also, at the same time if I get zone status via http request I can see the status of zones are getting changed correctly following by state of my reed sensors. But status of related binary sensors in HA are not updated at all…

Anyone experienced with such problem?
