This is a great product. I had difficulty connecting the device to my Ubiquiti network, but I received immediate help and advice from the store owner. Once it was connected, I also received further help to integrate the device into Home assistant. I should have read the manual with closer attention because all of the issues I hit were described in the documentation. Thank you Serge for all your assistance and selling this great product.
