Slope Control of lights (in Modbus, MQTT etc.)

Feature Requests

Hello,

I have noticed that the edge control option is missing in HA.

You often have impulse relays or devices that have integrated logic themselves. Here it is then necessary that a function, for example light_on, can be triggered with a pulse.

I would suggest a YAML integration in the following way (using Modbus as an example):

    lights:
      - name: "light"
        unique_id: "light"
        address: 1
        write_type: coil
        command_on_slope: 1s
        command_off_slope: 1s
        verify:
            input_type: coil
            address: 8192
            state_on: 1
            state_off: 0

This is currently only possible in a very complicated way via automation.
Another cool option would be that the output is only set when the UI button is pressed. The actual value is then returned via verify.

I hope my Request get implemented.
