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.

What about a kinetic light switch instead of a doorbell? They work with mains electricity rather than a relay, but it might be closer to your needs. If you fiddle around enough, you could find a self-compatible set of doorbell and switch where you could pair a doorbell button to a light switch unit.

Or you could use the light switch button (some are ip65, apparently) and draw a doorbell symbol on it. Some industrial units I've been to have a massive button as a doorbell at the gates.

The problem with light switches is that they are latched relays that typically only output line voltage, whereas I need a momentary relay that passes through 16V AC from the doorbell transformer. Do you know if some way to adapt this to my needs?
