How to build digital property?

Hello, the real estate is digitized. Owners can know the situation of the community at any time through mobile phones or computers, and communicate with property management companies, industry committees and other businesses in real time. Digitalization has a powerful service function. For example, merchants can keep abreast of all kinds of information in the community at any time, and can know whether there is water and electricity cut off at home and whether the package is delivered by express delivery through the digitalization of the property, and can provide various services such as repair, payment, complaint and remote control for the owners. Through various digital functions, I know the life information around the community like the back of my hand, making life more convenient.
