Star star intelligent door lock management software v 15 I am installing this software now, and there is a room in the room number setting.

I used it for two years, and now a window pops up saying that the authorization code has expired. If I get promoted, I asked the customer service and said I would charge a year's fee. When I installed it, I didn't say there would be a charge in the future. I said it was free. Now I have hidden consumption. Isn't this cheating? Black-hearted merchants spend a lot of money to install locks and spend money on authorization codes every year.
