Thanks JD. Haven’t seen this specific model and I can’t seem to find any Z-Wave compliance certification documents either for it. It’s very likely a rebranded Danalock like you mentioned.
It should work with SmartThing like a Danalock V3. If you get the lock @Marcin_Karnowski try using this DTH to make it work with ST [RELEASE] Universal Enhanced Z-Wave Lock, Schlage, Yale, Kwikset, IDLock, DanaLock, August Pro, Samsung, Locstar, KeyWe Locks and Popp Z-Wave Keypad Device Handler with Alarm Control, Notification, RFID, Door Sensor and advanced features
After you’ve paired it with your hub feel free to PM me and send me the MSR for the lock (you can find this printed by the DTH or from your My Devices page) and also the Raw Description for your lock from your My Devices page and I can tell you what features it’ll support with ST.
