Roombanker RGBW202 SSH local access

A few days ago I bought Roombanker Home Security Hub, which is a brand of Dusun, but has bad support so I decide to ask in the community here about accessing the system over SSH and admin user credentials. I recognized, that it is similar to DSGW-210-HA or DSGW-230, but I cannot access over ssh with the default credentials for both of them.
Can you please help me in my case of desperation:)?

cheers,
Ico
