Home automation is the residential extension of building automation.

It is automation of the home, housework or household activity.

Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Does this exist? Kinetic-powered wireless doorbell button that can trigger a relay instead of an electronic chime box (alien.top)

Wireless doorbell systems that have a kinetic-powered button (i.e. no battery) exist, e.g. https://www.amazon.com/gp/product/B0929729L1

Wireless relay receivers also exist, e.g. https://www.amazon.com/gp/product/B0B125VLNB

These products often use the 433 MHz band. Are there any that actually work together? What I really want is a kinetic-powered doorbell button that triggers a relay instead of a chime box.

You need an EV1527 compatible transmitter (the receiver linked is the common EV1527 type).
